Additional examples of fillers that can be used include maltodextrin, dextrose, calcium carbonate, calcium phosphate, lactose, mannitol, xylitol, and sorbitol. Combinations of these fillers can also be used.
[0089] As used herein, "starch" can refer to pure starch, modified starch, or starch derivatives derived from any source. Starch, typically in granular form, is present in almost all green plants in various plant tissues and organs (e.g., seeds, leaves, rhizomes, roots, tubers, shoots, fruits, grains, and stems). Starch composition, granule shape, and particle size can vary. Starches derived from different sources often have different chemical and physical properties. A particular starch can be selected for inclusion in a formulation based on the ability of the starch-based material to impart specific sensory properties to the formulation. Starch derived from a variety of sources can be used. For example, major sources of starch include cereals (e.g., rice, wheat, and corn) and root vegetables (e.g., potato and cassava). Other examples of starch sources include acorn, arrowroot, arracacha, banana, barley, beans (e.g., broad beans, lentils, mung beans, peas, chickpeas), breadfruit, buckwheat, canna, chestnut, taro, potato, kudzu, malanga, millet, oats, oka, Polynesian arrowroot, sago, sorghum, sweet potato, quinoa, rye, tapioca, taro, tobacco, water chestnut, and yam. Certain starches are modified starches. Modified starches have undergone one or more structural modifications, i.e., generally designed to alter their high-temperature properties. Some starches have been developed through genetic engineering and are considered "modified" starches. Other starches are modified after they are obtained. For example, modified starches can be starches that have undergone chemical reactions such as esterification, etherification, oxidation, acid-catalyzed or base-catalyzed depolymerization (thinning), bleaching, transglycosylation and depolymerization (e.g., dextrinization in the presence of a catalyst), cross-linking, enzyme treatment, acetylation, hydroxypropylation, and / or partial hydrolysis. Other starches are modified by pregelatinization, dextrinization, and / or thermal treatments such as cold water swelling.Specific modified starches include phosphated starch, glycerol cross-linked starch, phosphate cross-linked starch esterified with sodium trimetaphosphate, phosphate monoesterified phosphate cross-linked starch, acetylated phosphate cross-linked starch, starch acetate esterified with acetic anhydride, starch acetate esterified with vinyl acetate, acetylated adipate cross-linked starch, acetylated glycerol cross-linked starch, hydroxypropyl starch, hydroxypropylglycerol cross-linked starch, and starch sodium octenyl succinate.

[0102] In some embodiments, the binder comprises pectin. Pectin is a natural polymer that is an acidic heteropolysaccharide (a polysaccharide composed of multiple monosaccharide units) related to carbohydrates. Unlike common carbohydrates, pectin contains a carboxylic acid group (or the corresponding methyl ester or carboxamide group) at the C-6 position instead of a hydroxymethyl group. The main subunit is known as galacturonic acid, which can copolymerize with L-rhamnose. Other sugars are present as side-chain substituents. Pectin acts as a thickening and gelling agent. Pectin isolated from raw materials, such as apple pomace, citrus peel, sugar beet waste from the sugar processing process, sunflower flower discs discarded after seed harvesting, mango residue, and other commercially available pectins, can be used. In combination with certain sugars, under acidic conditions (e.g., pH of about 2.5 to about 5) or in the presence of gelling agents (calcium or other divalent alkaline earth elements), pectin can impart a gel-like or gummy consistency to the formulations disclosed herein. In some embodiments, the binder comprises low-methoxy pectin. Suitable low-methoxy pectins include, for example, "GENU® pectin type LM-104 AS" available from CP Kelco, Atlanta, GA, USA. In some embodiments, the binder comprises low-methoxy pectin in combination with a gelling agent.

[0138] The oral formulations described herein can take a variety of forms, including soft lozenges and chews.
[0139] solid oral dosage forms As described herein, the oral formulation is in a solid form. As used herein, the term "solid" means that the formulation can substantially maintain its physical shape when not supported by external means, such as packaging. Thus, the formulation is considered to be solid, solid-like, solid-form, or solid-like at room temperature. For the avoidance of doubt, a solid formulation remains substantially solid up to 30°C. In some embodiments, the oral formulation is in a solid form, such as a chew or soft lozenge. In some embodiments, the oral formulation is a chew or soft lozenge. In some embodiments, the oral formulation may be a chewing gum product.

[0143] Kiss In some embodiments, the formulations can be chewable, meaning that the formulation has a gentle elasticity or "bounce" when chewed and a desirable degree of plasticity. Chewable formulations can dissolve completely or can be in the form of a non-dissolving gum in which only certain ingredients (e.g., active ingredients, flavors, sweeteners) dissolve, leaving a non-dissolving matrix.
[0144] As described herein, a "chew" may be a confectionery-type formulation that can be chewed by the user before dissolving in the oral cavity (i.e., a dissolvable chew) or may be a chewing gum. Preferably, the "chew" completely dissolves in the user's oral cavity. The formulation may be dissolvable. As used herein, the terms "dissolve," "dissolving," and "dissolvable" refer to a formulation having water-soluble components that interact with the moisture in the oral cavity and go into solution, allowing the formulation to be gradually ingested. In one embodiment, a dissolvable formulation can remain in the user's oral cavity for a given period of time until completely dissolved. Dissolution rates can vary over a wide range, from about 1 minute or less to about 60 minutes. For example, a rapid-release formulation typically dissolves and / or releases the desired ingredient (e.g., active ingredient, flavor, etc.) in about 2 minutes or less, often about 1 minute or less (e.g., about 50 seconds or less, about 40 seconds or less, about 30 seconds or less, or about 20 seconds or less). Dissolution can occur by melting, mechanical disruption (eg, chewing), enzymatic or other chemical degradation, or by disruption of interactions between components of the formulation.
[0145] In other embodiments, the formulation does not dissolve while the formulation resides in the user's mouth.

[0182] For example, the chews can be coated with an overcoat material. Equipment for applying outer coatings to compressed pelletized compositions is available from Thomas Engineering, including the CompuLab 24, CompuLab 36, Accela-Cota 48, and Accela-Cota 60.
[0183] If present, the coating may comprise a film-forming polymer such as a cellulose-based polymer, an optional plasticizer, and any flavoring, coloring, salt, sweetener, or other additive described herein. The coating composition may be aqueous in nature and may be applied using any pellet or tablet coating technique known in the art, such as pan coating. Examples of film-forming polymers include cellulose-based polymers such as methylcellulose, hydroxypropyl cellulose (HPC), hydroxypropylmethylcellulose (HPMC), hydroxyethyl cellulose, and carboxymethyl cellulose. Examples of plasticizers include aqueous solutions or emulsions of glyceryl monostearate and triethyl citrate. Additional coatings that may be used include food-grade shellac, oils such as sunflower oil, waxes such as carnauba wax, and combinations thereof.
[0184] Soft type lozenges In some embodiments, the formulations disclosed herein may be in the form of soft, dissolvable, lightly chewable lozenges for oral use. As used herein, the term "soft lozenge" refers to a dissolvable oral formulation made by solidifying a liquid or gel composition, such as a composition containing a gelling agent or binder, so that the final formulation becomes a hardened, solid gel. Alternatively, the soft lozenge formulation may be referred to as a soft lozenge. In certain embodiments, the soft lozenge formulations of the present disclosure are characterized by sufficient cohesion to withstand light chewing in the oral cavity without rapidly disintegrating. The soft lozenge formulations of the present disclosure typically do not exhibit the highly deformable chewing characteristics found in conventional chewing gums. See, for example, the smokeless tobacco soft lozenges, soft lozenge formulations, soft lozenge configurations, soft lozenge characteristics, and soft lozenge formulation or manufacturing techniques described in U.S. Patent Nos. 9,204,667 to Cantrell et al., 9,775,376 to Cantrell et al., and 10,357,054 to Marshall et al., each of which is incorporated herein by reference. Particular formulations may exhibit, for example, one or more of the following characteristics: crispy, granular, chewy, syrupy, pasty, fluffy, smooth, and / or creamy. In certain embodiments, the desired texture characteristic can be selected from the group consisting of adhesiveness, cohesiveness, density, dryness, friability, granularity, gumminess, hardness, weight, hygroscopicity, moisture release, mouthcoating, roughness, slipperiness, smoothness, viscosity, wettability, and combinations thereof.
[0185] The soft lozenge formulations of the present disclosure typically comprise a combination of active ingredients in an amount of about 0.1% to about 10% by weight of the oral formulation, a binder, and a sugar alcohol and / or sugar (e.g., as a filler component). Any active ingredient discussed herein is meant to be suitable for use as an active ingredient in a soft lozenge formulation according to the present disclosure.
[0186] In some embodiments, the active ingredients may be provided in the soft lozenge in liquid form or in dry powder or particulate form, hi some embodiments, each active ingredient in the active ingredient combination is provided in the soft lozenge in dry powder form.
[0187] The binder (or a combination of two or more binders) may be used in an amount sufficient to impart desired physical properties and physical integrity to the soft lozenge formulation. In some embodiments, the binder of the soft lozenge may include pectin or gum. A representative amount of binder (e.g., pectin or gum) may comprise at least about 5% or at least about 10% of the total weight of the soft lozenge formulation. In certain embodiments, the binder (e.g., pectin or gum) is present in an amount of at least about 30% by weight, at least about 35% by weight, at least about 40% by weight, at least about 45% by weight, or at least about 50% by weight, based on the total weight of the oral formulation. In some embodiments, the binder (e.g., pectin or gum) may be present in an amount of about 35% to about 55% by weight of the oral formulation. Preferably, the total amount of binder (e.g., pectin or gum) in the soft lozenge formulation does not exceed about 55% by weight of the oral formulation. In most cases, the amount of binder (eg, pectin or gum) in a desirable formulation will not exceed about 65% by weight of the oral formulation, and usually will not exceed about 60% by weight.
[0188] In some embodiments, the binder may include pectin. Soft lozenge formulations may include pectin as the only binder, or pectin may be included in combination with a gum.
[0189] In certain embodiments, the binder is or includes a gum. The gum may include a natural gum. In particular, a natural gum (e.g., gum arabic, etc.) may be incorporated into the soft lozenge formulation as a softener. Advantageously, the use of a natural gum as a softener provides the desired texture qualities necessary to form the soft lozenge formulation, particularly the formulations described herein. In particular, it is noted that increasing the amount of natural gum (e.g., gum arabic) and then decreasing the amount of sugar alcohol and / or sugar can advantageously increase the flexibility of the resulting soft lozenge formulation. As used herein, natural gum refers to a naturally occurring polysaccharide material useful as a softener. Representative natural gums of plant origin, which are typically water-soluble to some extent, include xanthan gum, guar gum, gum arabic, gum ghatti, gum tragacanth, gum karaya, locust bean gum, gellan gum, and combinations thereof. Preferably, gum arabic may be used as an exemplary natural gum that provides the above softening properties when incorporated into the soft lozenge formulations of the present disclosure.
[0190] As noted above, the soft lozenge formulations of the present disclosure may contain at least one sugar, or at least one sugar alcohol, or a combination of at least one sugar and at least one sugar alcohol (e.g., in the form of a filler component). Sugar alcohols are particularly advantageous as filler components in the soft lozenges of the present disclosure, because such materials contribute some sweetness without compromising the desired chewable properties of the final formulation. In some embodiments, the sugar alcohol may be selected from the group consisting of maltitol, sorbitol, erythritol, mannitol, lactitol, xylitol, and isomalt. In some embodiments, isomalt may be incorporated as the only filler component. The sugar alcohol and / or sugar are typically added to the formulations of the present disclosure in the form of an aqueous solution or suspension, such as a solution or suspension having a solids content of about 50 to about 90% by weight. Combinations of sugar alcohols and / or sugars with additional filler components may also be used. Bulking agents often serve multiple functions, such as improving certain sensory properties, such as texture and mouthfeel, and improving the cohesiveness or compressibility of the formulation. In some embodiments, the bulking agent comprises a sugar substitute, such as one or more of allulose, water-soluble tapioca fiber, and inulin. Such sugar substitutes may be substitutes for sugar alcohols or may be used in combination with one or more sugar alcohols.
[0191] Melt Type In some embodiments, the formulations can be meltable, for example, as described in U.S. Patent Application Publication No. 2012 / 0037175 to Cantrell et al., which is incorporated herein by reference in its entirety.
[0192] As used herein, "melt," "melting," and "meltable" refer to the ability of a formulation to change from a solid state to a liquid state. That is, melting occurs when a substance (e.g., a formulation disclosed herein) changes from a solid to a liquid, usually by heating.
[0193] The heating of the formulations disclosed herein is provided by the temperature inside the user's mouth. Thus, the term "meltable" refers to a formulation that can be liquefied in the user's mouth when the formulation undergoes a phase change from solid to liquid, and is intended to distinguish it from a formulation that simply disintegrates in the mouth due to the loss of cohesion of the formulation, which simply dissolves in the mouth when the water-soluble components of the formulation interact with moisture.
[0194] Generally, meltable formulations include lipids. In some embodiments, the composition includes lipids. Lipids are fatty, oily, or waxy components typically derived from animal or plant sources (e.g., plant-derived fats) and typically contain primarily triglycerides with minor amounts of free fatty acids and monoglycerides or diglycerides. In certain embodiments, the lipids are solid or semi-solid at room temperature (i.e., 25°C) and can be at least partially liquefied (i.e., "melted") upon exposure to the temperature of a user's mouth. Exemplary plant-derived fats are primarily composed of saturated or unsaturated fatty acid chains (mostly attached in triglyceride structures) having carbon chain lengths of about 10 to about 26 carbon atoms, or about 14 to about 20 carbon atoms, or about 14 to about 18 carbon atoms.
[0195] In some embodiments, the lipid comprises an oil, particularly a food-grade oil, including fractionated oils. Such oils include vegetable oils (e.g., acai oil, almond oil, amaranth oil, apricot oil, apple seed oil, argan oil, avocado oil, babassu oil, beechnut oil, ben oil, bitter melon seed oil, black seed oil, black currant seed oil, borage seed oil, Borneo taro nut oil, bottle gourd seed oil, Brazil nut oil, buffalo gourd oil, butternut squash seed oil, Cape chestnut oil, canola oil, carob oak seed oil, and the like). Dew oil, cocoa butter, oakleber oil, coconut oil, corn oil, cosun oil, coriander seed oil, cottonseed oil, date seed oil, zika oil, egus seed oil, evening primrose oil, eggplant oil, linseed oil, grape seed oil, grapefruit seed oil, hazelnut seed oil, hemp oil, kapok seed oil, kenaf seed oil, lalemantia oil, lemon oil, linseed oil, macadamia oil, mafra oil, marula oil, meadowfoam seed oil, mongongo nut Oil, Mustard Oil, Niger Seed Oil, Nutmeg Butter, Okra Seed Oil, Olive Oil, Orange Oil, Palm Oil, Papaya Seed Oil, Groundnut Oil, Pecan Oil, Perilla Seed Oil, Perilla Seed Oil, Pequi Oil, Pili Nut Oil, Pine Nut Oil, Pistachio Oil, Pomegranate Seed Oil, Poppy Seed Oil, Praxi Oil, Prune Seed Oil, Pumpkin Seed Oil, Quinoa Oil, Rapeseed Oil, Rice Bran Oil, Royle Oil, Sacha Inchi Oil, Safflower Oil, Sapote Oil, Seji oil, sesame oil, shea butter, soybean oil, sunflower oil, tarramilla oil, tea seed oil, thistle oil, tiger nut oil, tobacco seed oil, tomato seed oil, walnut oil, watermelon seed oil, wheat germ oil, and combinations thereof), animal oils (e.g., beef tallow, buffalo tallow, mutton tallow, goat tallow, lard, camel tallow, tallow, liquid margarine, fish oil, fish liver oil, whale oil, seal oil, and combinations thereof), and mineral oils.
[0196] In certain embodiments, the plant-derived fats of the present disclosure include palm oil, palm kernel oil (including fractionated palm oil), soybean oil, cottonseed oil, and mixtures thereof. In one embodiment, the lipid is a blend of palm oil and palm kernel oil. The lipid may be, for example, hydrogenated, partially hydrogenated, or non-hydrogenated. Exemplary embodiments of lipids can be purchased under the trade names CEBES®, CISAO®, or CONF AO®, available from AarhusKarlshamn USA Inc.
[0197] The melting point of the lipid is typically about 29°C or higher, e.g., about 29°C to about 49°C, or about 36°C to about 45°C, or about 38°C to about 41°C. In some embodiments, the use of lipids with melting points below about 36°C is not suitable due to the possibility of melting during storage or handling of the formulation. One test for determining the melting point of a lipid is the Mettler Dropping Point Method (ASTM D3954-15, Standard Test Method for Dropping Point of Waxes, ASTM International, West Conshohocken, PA, 2015, www.astm.org.).
[0198] When present, the amount of lipid in the composition may vary. In certain embodiments, the amount of lipid is at least about 10%, at least about 20%, or at least about 30% by dry weight of the composition. In certain embodiments, the amount of lipid is less than about 70%, less than about 60%, or less than about 50% by dry weight. Exemplary lipid weight ranges include about 10 to about 70% by dry weight, e.g., about 35 to about 50% by dry weight. In some embodiments, the amount of lipid is about 35, about 40, about 45, or about 50% by weight of the total oral formulation.
[0199] In some embodiments, the oral formulation comprises a lipid. In one embodiment, the lipid is an oil selected from the group consisting of palm oil, palm kernel oil, soybean oil, sunflower oil, cottonseed oil, coconut oil, and combinations thereof, and the oil may be hydrogenated, partially hydrogenated, or non-hydrogenated. In one embodiment, the lipid is a medium-hardness trans-hydrogenated filling fat such as Confao® 5, available from AarhusKarlshamn USA Inc., 131 Marsh Street, Port Newark, NJ 07114.
[0200] In some embodiments, the dissolvable formulation comprises lipid in an amount of about 35% to about 50% by weight of the oral formulation and sugar alcohol in an amount of about 35% to about 55% by weight of the oral formulation. In some embodiments, the sugar alcohol is isomalt, erythritol, sorbitol, arabitol, ribitol, maltitol, dulcitol, iditol, mannitol, xylitol, lactitol, or a combination thereof. In some embodiments, the sugar alcohol is or includes isomalt. In some embodiments, a sugar substitute may be a sugar alcohol substitute or may be used in combination with one or more sugar alcohols. Suitable sugar substitutes include allulose, water-soluble tapioca fiber, inulin, and combinations thereof.
[0201] tablet In certain embodiments, the formulation is in the form of a compressed or molded tablet. Exemplary tablet dosage forms have a weight of about 250 mg to about 1500 mg, e.g., about 250 mg to about 700 mg, or about 700 mg to about 1500 mg. Tablets can have any of a variety of shapes, including conventional tablet shapes.
[0202] Generally, tablet formulations comprise a glucose-polysaccharide blend and a sugar alcohol. In some embodiments, the glucose-polysaccharide blend is present in an amount of about 35 to about 50% by weight, based on the total weight of the formulation, and the sugar alcohol is present in an amount of about 30 to about 45% by weight, based on the total weight of the formulation. In some embodiments, the sugar alcohol is isomalt, erythritol, sorbitol, arabitol, ribitol, maltitol, dulcitol, iditol, mannitol, xylitol, lactitol, or a combination thereof. In some embodiments, the sugar alcohol is or comprises isomalt.
[0203] When in tablet form, the formulation may be dissolvable. As used herein, the terms "dissolve," "dissolving," and "dissolvable" refer to a formulation having water-soluble components that interact with the moisture in the oral cavity and dissolve into solution, allowing the formulation to be gradually ingested. In one aspect, a dissolvable formulation can remain in the user's oral cavity for a given period of time until completely dissolved. The dissolution rate can vary over a wide range, from about 1 minute or less to about 60 minutes. For example, immediate-release formulations typically dissolve and / or release the desired components (e.g., active ingredient, flavor, etc.) in about 2 minutes or less, often about 1 minute or less (e.g., about 50 seconds or less, about 40 seconds or less, about 30 seconds or less, or about 20 seconds or less). Dissolution can occur by melting, mechanical disruption (e.g., chewing), enzymatic or other chemical degradation, or by disruption of interactions between the components of the formulation. In other embodiments, the formulation does not dissolve while the formulation remains in the user's oral cavity.
[0204] Lozenges In some embodiments, the formulations disclosed herein may be in the form of dissolvable lozenges adapted for oral use. Exemplary lozenge-shaped formulations of the present invention have the form of lozenges, tablets, microtablets, or other tablet-like formulations. See, for example, U.S. Patent No. 4,967,773 to Shaw, U.S. Patent No. 5,110,605 to Acharya, U.S. Patent No. 5,733,574 to Dam, U.S. Patent No. 6,280,761 to Santus, U.S. Patent No. 6,676,959 to Andersson et al., U.S. Patent No. 6,248,760 and U.S. Patent No. 7,374,779 to Wilhelmsen, and U.S. Patent Application Publication No. 2001 / 0016593 to Wilhelmsen, all of which are incorporated herein by reference. and U.S. Patent Application Publication No. 2010 / 0004294 to Axelsson et al., ...
[0205] Troche formulations are generally described as "hard" and are distinguished from soft troches (i.e., soft-type troches) as follows: Hard troches are mixtures of sugars and / or carbohydrates in an amorphous state. Hard troches are made from an aqueous sugar solution; however, the water initially present evaporates as the sugar solution boils during processing, so the moisture content of the final formulation is very low, e.g., 0.5% to 1.5% by weight. To obtain a hard, non-sticky troche, the temperature of the melt must generally reach a hard crack stage, an exemplary temperature range of 149° to 154°C.
[0206] In some embodiments, the lozenge formulation may exhibit translucency or transparency. The desired transparency or translucency of a formulation can be quantified by any known technique. For example, optical measurements such as turbidity (or scattered light measurement) and colorimetry can be used to quantify the turbidity (light scattering) and color (light absorption) of the formulation, respectively. Translucency can also be confirmed by visual inspection by simply holding the formulation level with a light source and determining whether light diffusely passes through the material or formulation.
[0207] The lozenge formulations of the present disclosure can incorporate a variety of different additives in addition to the combination of active ingredients and can be prepared by a variety of different methods for preparing lozenges that are generally known in the art. Exemplary compositions, formulations, and methods for preparing such formulations are detailed herein below.
[0208] The lozenge formulations of the present disclosure typically comprise a composition comprising a combination of an active ingredient in an amount of less than about 2% by weight, a sugar substitute in an amount of at least about 80% by weight, and a sugar alcohol solution. Any active ingredient discussed herein is suitable for use as an active ingredient in the lozenge formulations provided herein. In some embodiments, the active ingredient may be provided in liquid form or in dry powder or particulate form. As described above, the active ingredient is typically present in an amount of about 0.1% by weight to about 10% by weight, for example, about 0.1% by weight to about 10% by weight, such as about 0.1% by weight, about 0.5% by weight, about 1% by weight, about 1.5% by weight, about 2% by weight, about 2.5% by weight, about 3% by weight, about 3.5% by weight, about 4% by weight, about 4.5% by weight to about 5.5% by weight, about 6% by weight, about 6.5% by weight, about 7% by weight, about 7.5% by weight, about 8% by weight, about 8.5% by weight, about 9% by weight, about 9.5% by weight, about 10% by weight, etc. In some embodiments, the active ingredient may be present in an amount of less than about 10% by weight, less than about 9% by weight, less than about 8% by weight, less than about 7% by weight, less than about 6% by weight, less than about 5% by weight, less than about 4% by weight, less than about 3% by weight, less than about 2% by weight, or less than about 1% by weight, based on the total weight of the formulation.
[0209] In some embodiments, the lozenge formulation comprises a sugar substitute. The sugar substitute is typically provided in a pure solid form (e.g., granular or powdered form). In certain embodiments, the sugar substitute is dry and has a very low moisture content. For example, the sugar substitute may contain less than about 5% water by weight, less than about 3% water by weight, less than about 2% water by weight, or less than about 1% water by weight. In certain embodiments, the sugar substitute is capable of forming a glassy matrix. The formation of a glassy matrix is generally characterized by a translucent / transparent appearance.
[0210] Typically, sugar substitutes are substantially non-hygroscopic. Non-hygroscopic materials typically do not absorb, adsorb, and / or retain substantial amounts of moisture from the air. Non-hygroscopic materials can provide the advantage of reducing the tendency of the lozenge formulation to stick when exposed to moisture. Sugar substitutes can be any sugar-free material (i.e., sucrose-free material) and can be natural or synthetically produced. Sugar substitutes used in the formulations described herein can be nutritive or non-nutritive. For example, sugar substitutes are generally sugar alcohols. Sugar alcohols that may be useful according to the present invention include, but are not limited to, erythritol, threitol, arabitol, xylitol, ribotol, mannitol, sorbitol, dulcitol, iditol, isomalt, maltitol, lactitol, polyglycitol, and mixtures thereof. For example, in certain embodiments, the sugar alcohol is selected from the group consisting of erythritol, sorbitol, and isomalt. The amount of sugar substitute in a lozenge formulation can vary, but is typically at least about 75%, at least about 80%, at least about 85%, or at least about 90%, or at least about 95% by weight of the formulation.
[0211] In certain embodiments, the sugar substitute comprises one or more sugar alcohols, for example, in one embodiment the sugar substitute is isomalt.
[0212] In some embodiments, the sugar substitute is one or more of allulose, water-soluble tapioca fiber, and inulin. Such sugar substitutes may be substitutes for sugar alcohols or may be used in combination with one or more sugar alcohols.
[0213] In some embodiments, the lozenge formulations of the present disclosure may contain a sugar solution, such as a sugar syrup or a sugar alcohol solution. As used herein, "sugar alcohol solution" is intended to refer to a highly concentrated aqueous solution of a sugar alcohol, e.g., having a solids content of greater than about 40%, preferably greater than about 50%, greater than about 60%, greater than about 70%, or greater than about 80%. Typically, the solids of a sugar alcohol solution are predominantly composed of a particular sugar alcohol (i.e., a maltitol solution typically contains greater than about 80%, greater than about 85%, or greater than about 90% by weight of maltitol on a dry basis). Sugar alcohol solutions are generally prepared by heating an aqueous solution of a sugar alcohol and cooling the mixture to obtain a viscous composition. The resulting sugar solution is typically characterized by a relatively high concentration of sugar alcohol and a relatively high stability (i.e., the sugar alcohol typically does not crystallize from solution, e.g., at room temperature).
[0214] Sugar solutions, such as sugar alcohol solutions, can desirably affect the recrystallization of melted sugar substitutes. One example of a particularly useful sugar alcohol solution according to the present disclosure is maltitol solution. Other sugar alcohol solutions can be used, including, but not limited to, corn solution, golden syrup, molasses, xylitol solution, mannitol solution, glycerol solution, erythritol solution, threitol solution, arabitol solution, ribitol solution, mannitol solution, sorbitol solution, dulcitol solution, iditol solution, isomalt solution, lactitol solution, and polyglycitol solution. Such sugar alcohol solutions can be prepared or obtained commercially. For example, maltitol solution is commercially available from suppliers such as Corn Products Specialty Ingredients. While sugar alcohol solutions may be preferred, in certain embodiments, sugar syrups can be used in place of or in combination with the sugar alcohol solution. For example, in some embodiments, corn syrup, golden syrup, and / or molasses can be used.
[0215] The amount of sugar alcohol solution added to the lozenge formulation mixture is typically an amount necessary to slow the recrystallization of the molten sugar substitute. It should be noted that the amount of sugar alcohol solution can be varied depending on the composition of the remaining ingredients to ensure that recrystallization is sufficiently slow to yield a material with the desired properties (e.g., a desired level of translucency / transparency). Thus, the amount of sugar alcohol solution can vary, but typically ranges from about 0.1% to about 2% by weight of the lozenge formulation mixture, often from about 0.5% to about 1.5% by weight, and more often about 1% by weight. In certain embodiments, the amount of sugar alcohol solution is higher, e.g., up to about 2% by weight of the mixture, up to about 5% by weight of the mixture, up to about 10% by weight of the mixture, or up to about 20% by weight of the mixture.
[0216] Representative lozenge compositions and formulations may incorporate up to about 10% by weight of a combination of active ingredients, about 0.01 to about 2% by weight of an artificial sweetener, about 1% to about 5% by weight of a humectant, about 1% to about 5% by weight of a natural sweetener, at least about 80% by weight of a sugar substitute, about 0.1% to about 10% by weight of a sugar alcohol solution, one or more flavorings in an amount up to about 5% by weight, and salt in an amount up to about 3% by weight, based on the total weight of the formulation. The specific proportions and selection of ingredients will vary depending on the flavor, texture, and other characteristics desired.
[0217] The oral formulations in the form of lozenges of the present disclosure may contain various amounts of water. The water content of the lozenges described herein can vary within the ranges described below depending on the desired properties and characteristics, and can determine the final form of the formulation before use by a consumer. For example, lozenge-shaped formulations typically have a water content in the range of about 0.1 to about 5% by weight of the formulation. Preferably, the water content of the lozenge formulation present in one unit of formulation before insertion into the user's oral cavity is less than about 5%, less than about 3%, less than about 2%, or less than about 1% by weight of the formulation. In some embodiments, the water content of the lozenge formulations described herein can be within the range of about 0.1% to about 5%, about 0.5 to about 3%, or about 1 to about 2% by weight of the formulation.
[0218] Powder or pouch-packaged preparations In some embodiments, the oral formulation may be in the form of a powder. The powder may be a free-flowing powder. The powder may be contained in a loose form in a container and thus may be used in a form similar to snuff, when the user takes a pinch of powder from the container and retains it in the oral cavity. Alternatively or additionally, the powder may be incorporated into a moisture-permeable (e.g., saliva-permeable) pouch similar to snus-type products. The pouch-packaged formulation may be configured to be inserted into the oral cavity of the user, i.e., may be a pouch-packaged oral formulation.
[0219] In some embodiments, the formulations of the present disclosure are in the form of pouch-packaged oral formulations. Such pouch-packaged formulations include an oral formulation described herein placed in a moisture-permeable container (e.g., a water-permeable pouch or a saliva-permeable pouch). For example, the pouch-packaged formulation may include an oral formulation in powder form incorporated into a saliva-permeable pouch.
[0220] Such compositions in the form of breathable pouches are typically used by retaining one pouch containing the composition in the oral cavity of a human subject / user. Generally, the pouch is retained somewhere in the user's oral cavity, for example, under the lips, in a manner similar to the normal use of moist snuff products. The pouch is preferably not chewed or swallowed. Upon exposure to saliva, some of the components of the composition therein (e.g., active ingredient and / or any flavoring) pass through, for example, the breathable pouch, providing flavor and a satisfying sensation to the user, without the user having to expectorate any portion of the composition. After about 10 to about 60 minutes of use / enjoyment, typically about 15 to about 45 minutes, once a significant amount of the composition has been ingested by the human subject, the pouch can be removed from the human subject's mouth for disposal.
[0221] In some embodiments, the pouch is saliva-permeable. This means that the pouch is made of a saliva-permeable pouch material. Pouch materials used in oral pouch-packaged formulations are typically dry-bonded nonwovens containing viscose rayon fibers (i.e., regenerated cellulose) and an acrylic polymer, which acts as a binder in the nonwoven material and allows the pouch to be heat-sealed during manufacturing. The pouch material may also contain synthetic fibers (e.g., polyester) in addition to viscose fibers. The viscose nonwoven material typically used in smokeless tobacco pouches is similar to the fibrous material used in tea bags. Nonwovens are fibrous materials that are neither woven nor knitted. Methods for manufacturing nonwoven materials are generally known in the art. For more information on nonwovens, see "Handbook of Nonwovens" by S. Russell, published by Woodhead Pub I. Ltd. in 2007. In some embodiments, the pouch material is a fleece material. In some embodiments, the pouch material is a nonwoven material. In some embodiments, the pouch material is a nonwoven fleece material. In some embodiments, the pouch material comprises viscose, e.g., viscose rayon fibers. In some embodiments, the pouch material comprises regenerated cellulose fibers. In some embodiments, the pouch material comprises polyester fibers, which may comprise the pouch material or may be included in combination with viscose (e.g., regenerated cellulose fibers).
[0222] In some embodiments, the pouch material includes a binder that allows the pouch to be heat sealed during manufacturing. In some embodiments, the pouch material includes an acrylic binder. In some embodiments, the pouch material includes an acrylic binder in combination with viscose and / or polyester fibers.
[0223] Suitable sachets, pouches, or containers of the type used to manufacture smokeless tobacco products are available under the trade names CatchDry, Ettan, General, Granit, Goteborgs Rape, Grovsnus White, Metropol Kaktus, Mocca Anis, Mocca Mint, Mocca Wintergreen, Kicks, Probe, Prince, Skruf, and TreAnkrare. The composition can be contained and packaged in a pouch in a manner similar to that used to manufacture conventional snus-type products, using various ingredients used in the manufacture of conventional snus-type products. The pouch functions as a moisture-permeable container, the type of which may be considered similar in characteristics to the mesh material used to manufacture tea bags. The ingredients of the composition readily diffuse through the pouch into the user's mouth. Non-limiting examples of suitable types of pouches are described, for example, in U.S. Pat. No. 5,167,244 to Kjerstad, U.S. Pat. No. 8,931,493 to Sebastian, U.S. Patent Application Publication No. 2016 / 0000140 to Sebastian et al., U.S. Patent Application Publication No. 2016 / 0073689 to Sebastian et al., U.S. Patent Application Publication No. 2016 / 0157515 to Chapman et al., and U.S. Patent Application Publication No. 2016 / 0192703 to Sebastian et al., each of which is incorporated herein by reference. The pouches can be provided as individual pouches or multiple pouches (e.g., 2, 4, 5, 10, 12, 15, 20, 25, or 30 pouches) can be connected or joined together (e.g., end to end) so that a single pouch or individual portion can be easily removed for use from an integral band or matrix of pouches.
[0224] Exemplary pouches can be manufactured from materials that allow controlled dispersion or dissolution of the pouch during use by the user. Such pouch materials can be in the form of mesh, screen, perforated paper, permeable fabric, etc. For example, a pouch material made from mesh-like rice paper or perforated rice paper can dissolve in the user's mouth. As a result, the pouch and composition can each completely disperse in the user's mouth under normal use conditions, and thus both the pouch and the composition can be ingested by the user. Other examples of pouch materials can be manufactured using water-dispersible film-forming materials (e.g., binders such as alginate, carboxymethylcellulose, xanthan gum, pullulan, etc.) and combinations of water-dispersible film-forming materials with comminuted cellulose (e.g., finely divided wood pulp). While preferred pouch materials are water-dispersible or soluble, they may also be designed and manufactured so that a significant amount of the composition contents can permeate the pouch material under normal use conditions before the pouch loses its physical integrity. If desired, flavoring ingredients, disintegration aids, and other desired ingredients may be incorporated into or applied to the pouch material.
[0225] The amount of oral formulation contained in each pouch-packaged formulation unit, e.g., one pouch, can vary. In some embodiments, the weight of the composition in each pouch is at least about 50 mg, e.g., about 50 mg to about 1 gram (1000 mg), e.g., about 100 mg to about 900 mg, e.g., about 200 mg to about 800 mg, e.g., about 500 mg to about 700 mg. In some smaller embodiments, the weight of the composition in each pouch can be about 100 mg to about 300 mg. In larger embodiments, the weight of the composition in each pouch can be about 300 mg to about 700 mg. If desired, other ingredients can be included in each pouch.
[0226] The moisture content of an oral formulation may vary depending on the form in which the composition is provided. In some embodiments described hereinabove, the oral formulation may be in the form of moist snuff or snus, and may be provided in pouch form. In some embodiments (e.g., in the case of snus-like formulations), the moisture content of the composition (before inserting the formulation into the user's oral cavity) may be at least about 20% by weight of the oral formulation, such as at least 30% by weight, for example at least 40% by weight, for example at least 50% by weight. In some embodiments (e.g., in the case of snus-like formulations, e.g., non-pouch or pouch-packaged snus-like formulations), the moisture content of the composition (before inserting the formulation into the user's oral cavity) may be about 20% by weight to about 70% by weight of the oral formulation, such as about 30% by weight to about 60% by weight, for example about 40% by weight to about 55% by weight.
[0227] In some embodiments, the oral formulation may be a "dry" snus- or snuff-like formulation. In such embodiments, the moisture content of the oral formulation may be about 10% or less, e.g., about 5% or less, by weight of the oral formulation. For example, the moisture content may be about 0.1% to about 10% by weight of the oral formulation, e.g., about 1% to about 5% by weight.
[0228] When in the form of a pouch-packaged oral formulation, the oral formulation typically contains a filler. The filler may be a cellulosic material, preferably selected from the suitable materials described above. In some preferred embodiments, the filler is or includes at least MCC. The amount of filler can vary, but is typically at least about 5% to about 95% by weight of the oral formulation, based on the total weight of the oral formulation. In some embodiments, the filler (e.g., a cellulosic material such as MCC) may be present in the oral formulation in an amount of about 5% to about 95% by weight, e.g., about 10% to about 90% by weight, e.g., about 15% to about 85% by weight, e.g., about 20% to about 80% by weight, e.g., about 25% to about 75% by weight, e.g., about 30% to about 70% by weight, e.g., about 35% to about 65% by weight, e.g., about 40% to about 60% by weight. In some embodiments, the filler (eg, a cellulosic material such as MCC) may be present in an amount of about 45% to about 55% by weight of the oral dosage form.
[0229] packaging According to some embodiments described herein, a package containing the oral formulation described herein is provided. For example, the package may contain the oral formulation in powder form. In such embodiments, the package may be in the form of a tinplate or plastic container. Alternatively or additionally, the package may contain the oral formulation in the form of a chew, lozenge, soft lozenge, tablet, etc. The package may be in the form of a blister pack, tinplate, or plastic container containing such oral dosage forms.
[0230] According to some embodiments described herein, there is provided a package containing at least one pouch-packaged oral formulation described herein. The pouch-packaged formulation described herein can be packaged in any suitable inner wrapper and / or outer container. See, for example, U.S. Pat. No. 7,014,039 to Henson et al., U.S. Pat. No. 7,537,110 to Kutsch et al., U.S. Pat. No. 7,584,843 to Kutsch et al., U.S. Pat.

For example, the package may be a tinplate or plastic container containing a plurality of pouch-packaged oral dosage forms.
[0231] In some preferred embodiments, where the oral formulation is in liquid form, a package in the form of a bottle or can containing the liquid oral dosage form is provided. The package may be a bottle containing a desired volume of the liquid oral dosage form.
[0232] method The manner in which the various components of the composition (e.g., active ingredient and optional additives) are combined can vary. Thus, for example, the overall formulation, including powdered composition components, can be relatively uniform (e.g., homogeneous) in nature. The above components, which can be in liquid or dry solid form, can be added by mixing in a pre-processing step before mixing with any remaining components of the formulation, or can simply be mixed with all other liquid or dry ingredients.
[0233] The various components of the formulation can be contacted, combined, or mixed using any mixing technique or device known in the art. Any mixing method that allows for intimate contact of the formulation components can be used, such as a mixing device featuring an impeller or other agitating structure. Examples of mixing devices include casing drums, adjusting cylinders or drums, liquid spray devices, conical blenders, ribbon blenders, mixers such as FKM130, FKM600, FKM1200, FKM2000, and FKM3000 available from Littleford Day, Inc., plowshare-type mixing cylinders, Hobart mixers, and the like. See also, for example, the various techniques described in U.S. Pat. No. 4,148,325 to Solomon et al., U.S. Pat. No. 6,510,855 to Korte et al., and U.S. Pat. No. 6,834,654 to Williams, each of which is incorporated herein by reference. In some embodiments, the components forming the formulation are prepared so that the mixture can be used in the starch forming method to form the formulation.The manner and method of formulating the product will be clear to those skilled in the art.See, for example, the various methods described in U.S. Patent No. 4,148,325 by Solomon et al., U.S. Patent No. 6,510,855 by Korte et al., U.S. Patent No. 6,834,654 by Williams, U.S. Patent No. 4,725,440 by Ridgway et al., and U.S. Patent No. 6,077,524 by Bolder et al., each of which is incorporated herein by reference.
[0234] Method for preparing chew formulations As described herein, the formulation is in chewable form. In such embodiments, the method comprises: (a) contacting at least one binder with at least one excipient selected from the group consisting of a sugar alcohol, or a sugar, or a combination of at least one sugar alcohol and at least one sugar, and optionally adding water; (b) heating a mixture of binder, sugar alcohol and / or sugar, and optionally water; (c) adding the combination of active ingredients; (d) solidifying the resulting mixture to obtain an oral chew formulation. may include:
[0235] The combination of active ingredients may be as described herein above. The combination of active ingredients may also be as described below in connection with "Further Broad Aspects."
[0236] Step (b) of heating the mixture may include heating the mixture to a temperature of about 70° C. to about 150° C., such as about 80° C. to about 125° C., such as about 90° C. to about 100° C. Step (b) may include heating the mixture to boiling, optionally while stirring the mixture.
[0237] Step (d) preferably includes a cooling step. In some embodiments, the mixture resulting from step (c) is cooled to solidify and provide an oral chew formulation. For example, after adding the active ingredient in step (c), the resulting mixture may be filled into a mold and the heat removed. The mixture may be passively cooled to room temperature. Alternatively, the mixture may be placed in a cold water bath, refrigerator, or freezer to reduce the temperature. Preferably, cooling is performed at room temperature to solidify the formulation.
[0238] The active ingredient combination may be added during heating step (b). In some embodiments, the active ingredient combination is added while the mixture of binder, sugar alcohol and / or sugar, and optionally water is boiling. Alternatively, the active ingredient combination may be added after the mixture of binder, sugar alcohol and / or sugar, and optionally water has cooled.
[0239] Optional additives may be added at any stage during the above process. In some embodiments, an acidifying agent is added after heating of the mixture is terminated, i.e., during step (c) or (d). In some embodiments, flavoring and / or coloring agents are added after heating of the mixture is terminated, i.e., during step (c) or (d). In some embodiments, a sweetener is added during step (a). Thus, a sweetener may be included in the mixture heated in step (b).
[0240] To prepare chewable formulations, a binder (e.g., pectin, agar, carrageenan, starch, or a combination thereof) is generally preblended with all or part of the sugar alcohol / sugar, sweetener, or combination thereof. Water is added and the mixture is heated to a boil with stirring. The remaining sugar alcohol or sweetener is added to the boiling mixture along with the active ingredient, followed by the optional buffer. The mixture is heated until it reaches about 50 to about 80 Brix. Heating is stopped, and optional acidifiers and / or flavoring agents are added along with optional coloring agents, and the mixture is thoroughly mixed. The composition is filled into molds for storage at ambient temperature.
[0241] In some embodiments, the composition is filled into starch molds. A starch tray with a molded shape is prepared and preheated to 60°C for at least 1-2 hours. The starch can be any starch as disclosed hereinabove. In some embodiments, the starch is corn starch. In some starch-molded embodiments, the pectin binder is pre-blended with a portion of the sugar alcohol (e.g., isomalt or maltitol). Water is added, and the mixture is heated to a boil while stirring. Additional sugar alcohol (e.g., maltitol syrup and / or isomalt) is added to the boiling mixture along with the active ingredient. The mixture is heated to about 78 Brix. Heating is stopped, and optional sweeteners (e.g., sucralose or acesulfame K) and flavoring agents are added along with optional colorants and acidifiers (e.g., citric acid solution), and the mixture is thoroughly mixed. The hot mixture is filled into starch molds for storage at ambient temperature. The resulting chew is removed from the starch mold, and excess starch is removed.
[0242] In other starch molded embodiments, gum powder (e.g., pectin, agar, carrageenan, starch, or a combination thereof) is mixed with water until no lumps remain. Sugar alcohols and / or sugars (e.g., isomalt and / or maltitol syrup) and optional sweeteners (e.g., sucralose) are mixed together and the mixture is heated to 82-104°C. The gum powder solution is added to the sugar alcohol / sugar and mixed thoroughly. Active ingredients, optional colors and flavors are added to the solution and mixed thoroughly. The mixture is heated at 93-104°C until the Brix reaches 50-80. An aqueous solution of an acidifying agent (e.g., citric acid and / or trisodium citrate dihydrate) is prepared and added to the hot mixture. An optional gelling agent (e.g., dicalcium phosphate solution) is then added to the mixture, if desired. The hot mixture is filled into the prepared starch molds and placed in a 60°C oven overnight, or until properly set. The resulting chew is removed from the starch mold and excess starch is removed. In some embodiments, the chew is coated with, for example, a coating oil or CAPOL 410 (available from Centerchem, Inc.). The coating process can be carried out in the same manner as described in detail below for the soft lozenge formulation.
[0243] In other embodiments, the composition is filled into starch-free molds. In such embodiments, gum powder (e.g., pectin, agar, carrageenan, starch, or a combination thereof) is mixed with water until no lumps remain. Maltitol syrup, sucralose, and optionally isomalt are mixed together, and the mixture is heated to 82-104°C. The gum powder solution is added to the maltitol solution and mixed thoroughly. The active ingredient(s), optional colorants and flavoring agents are added, and the mixture is thoroughly mixed. The mixture is heated at 93-104°C until the Brix reaches 50-80. An aqueous solution of citric acid and, optionally, trisodium citrate dihydrate is prepared and added to the hot mixture to achieve a pH of 2.5-4. An optional gelling agent (e.g., dicalcium phosphate solution) is then added to the mixture, if desired. The hot mixture is filled into non-starch molds and allowed to stand at room temperature until properly set.
[0244] The chew formulation may be held in the mold (starch or non-starch) for a period of time, such as from about 10 minutes to about 24 hours, or even 48 hours, to allow the chew formulation to harden and set.
[0245] According to another aspect of the present disclosure, rather than using a mold to prepare the chew formulation, an extrusion process can be used in which the final chew formulation is extruded as described below with respect to the soft lozenge extrusion method.
[0246] Method for preparing soft lozenge formulation The methods and techniques used to formulate and manufacture the soft lozenge formulations described herein can vary. For example, the composition for forming the soft lozenge formulation can be prepared so that the mixture can be used in a starch molding method to form the soft lozenge formulation. Exemplary soft lozenge manufacturing processes are described in U.S. Pat. No. 4,725,440 to Ridgway et al. and U.S. Pat. No. 6,077,524 to Bolder et al., each of which is incorporated herein by reference. In some embodiments, the composition for forming the soft lozenge formulation can be prepared so that the mixture can be used in a non-starch molding method (e.g., a molding method that does not include starch-based components) to form the soft lozenge formulation.
[0247] In some embodiments, the method includes heating the gum, optionally hydrating the gum ingredients with water, and then stirring the active ingredient combination into the heated gum ingredients. Generally, the gum may be heated to a temperature ranging from about 60°C to about 80°C for a period of a few seconds to a few minutes. In some embodiments, the gum may be heated to a temperature of about 71°C before stirring with the active ingredient combination to dissolve the active ingredients therein. In some examples, the aqueous mixture is formed in a separate container by mixing one or more additives (e.g., salt, sweeteners, humectants, emulsifiers, flavors, etc.) with water to form the aqueous mixture.
[0248] The aqueous mixture can then be mixed with the heated gum (including at least one active ingredient added thereto) to form a mixture in the form of a slurry. In some embodiments, at least one sugar alcohol / sugar component can be added separately to this mixture, or in other embodiments, the at least one sugar alcohol / sugar can be mixed with the gum and active ingredient before being added to the mixture. In some examples, the at least one sugar alcohol / sugar can be heated in a separate container and added separately to the mixture. For example, in some embodiments, the at least one sugar alcohol / sugar (which may optionally include isomalt / maltitol / erythritol) can be heated to a temperature in the range of about 160°C to about 190°C before being added to the mixture. In some embodiments, the at least one sugar alcohol / sugar can be heated to a temperature of at least about 160°C, at least about 170°C, at least about 180°C, or at least about 190°C. In some examples, the heated sugar alcohol / sugar can be allowed to cool to a temperature in the range of about 120°C to about 160°C before being added to the mixture. In some embodiments, for example, the heated sugar alcohol / sugar may be cooled to a temperature of about 160°C or less, about 150°C or less, about 140°C or less, or about 130°C or less before being added to the mixture.
[0249] In some examples, the soft lozenge composition, which may be in the form of a slurry, may be obtained by mixing the heated (and optionally cooled) sugar alcohol / sugar with a mixture (e.g., including the heated gum, at least one active ingredient, and an aqueous mixture) and stirring using a high-shear mixer or a Hobart mixing bowl equipped with a whipping attachment. The soft lozenge composition may then be heated to an elevated temperature, e.g., from about 40°C to about 80°C, typically about 71°C, for about 1 minute to about 3 minutes, for example, to dissolve the dry ingredients within the soft lozenge composition. The heating step may be characterized as heating at a temperature of at least about 50°C, at least about 60°C, or at least about 70°C. The soft lozenge composition may typically have a moisture content of at least about 40% by weight, based on the total weight of the composition.
[0250] According to some embodiments, a soft lozenge composition in a slurry form may optionally undergo a degassing step or degassing process to reduce or remove air bubbles present in the slurry mixture before being poured into a mold or subjected to other processing steps. Air bubbles trapped in the slurry may affect the final weight of the soft lozenge formulation and may compromise the unit-to-unit weight uniformity of the final formulation. Therefore, any degassing method and system may be used to remove such air bubbles from the slurry material. For example, the slurry may be placed under reduced pressure (i.e., atmospheric pressure) to extract the air bubbles from the slurry mixture. In some examples, a vacuum degassing process may be employed in which the slurry mixture is placed in a vacuum degassing device to degas the slurry mixture by reducing the pressure. In some examples, the slurry mixture may be placed under vacuum for about 1 to about 10 minutes, typically about 3 to about 5 minutes. The degassing step may be monitored and adjusted as necessary to control the removal of gaseous components from the slurry mixture.
[0251] The viscosity of the heated and deaerated slurry mixture may be measured, for example, using a Brookfield HA series viscometer, an SC4 water jacket, a 27 / 13R sample chamber, and a No. 27 spindle. The soft lozenge composition may have a viscosity of about 5.7 Pascal seconds (Pa·s) to about 6.2 Pa·s when heated to a temperature of about 38° C., about 4.9 Pa·s to about 5.4 Pa·s when heated to a temperature of about 43° C., and about 4.2 Pa·s to about 4.7 Pa·s when heated to a temperature of about 50° C. In some examples, additional water may be added to the soft lozenge composition to provide the desired viscosity.
[0252] Once the desired viscosity is achieved, the heated soft lozenge composition may then be filled into molds, such as, for example, starch molds. It should be noted that while the process described further herein is directed to forming soft lozenge formulations using starch molds, other types of molds may also be used in the process, such as, for example, non-starch molds, pectin molds, plastic tray molds, silicone tray molds, metal tray molds, neoprene tray molds, etc.
[0253] When using a starch mold, the starch mold may be pre-dried to remove moisture from the starch mold itself. That is, the starch mold may be exposed to high temperatures to remove moisture from the starch mold before the slurry or viscous soft lozenge composition is poured into it. For example, in some instances, the starch mold may initially have a moisture content of about 10-15% by weight. Moisture at such levels may affect the uniformity of the resulting product. In this regard, certain moisture levels in the starch mold may cause the product to wrinkle or shrink, resulting in a deflated or otherwise wrinkled appearance of the final formulation. Thus, the starch mold may be dried at high temperatures to reduce the moisture content of the starch mold to about 4-10% by weight, preferably about 6-8% by weight, based on the total weight of the starch mold. Taking such a step may, in some instances, result in a more uniform and consistent appearance of the formulation. Additionally, the starch mold may be heated to a high temperature before being injected with the soft lozenge composition so that the starch mold itself is at a high temperature when it receives the lozenge composition.
[0254] The soft lozenge composition may be held in the starch mold at an elevated temperature, such as about 40°C to about 80°C (e.g., at least about 40°C or at least about 50°C), typically about 60°C. The soft lozenge composition may be held at the elevated temperature for a predetermined period of time, such as about 12 to 48 hours, typically about 24 hours, so that the soft lozenge composition hardens and solidifies into a soft lozenge shape, and the moisture content of the composition is reduced to a desired final moisture level. As noted above, in some embodiments, the desired final moisture level of the soft lozenge formulation may be within a range of about 5 to about 25% by weight, or about 8 to about 20% by weight, or about 10 to about 15% by weight, based on the total weight of the formulation unit. In this regard, hardening generally refers to the solidification process during which moisture loss occurs, the viscosity of the composition increases, and chemical and physical changes begin to occur (e.g., crystallization, crosslinking, gelation, film formation, etc.). The soft lozenge composition is cooled and then removed from the starch mold. In some instances, the soft lozenge composition may be cooled to refrigeration temperatures or below ambient temperature. A blower or shaker device may be used to remove starch residue from the soft lozenge composition after it has been removed from the starch mold.
[0255] The soft lozenge formulation is then post-cured for a time and temperature suitable to equilibrate the desired moisture, shape, and configuration. The time and temperature can vary without departing from the scope of the invention and depend, in part, on the desired final properties of the formulation. In one embodiment, post-curing occurs at ambient temperature for at least about 20 hours after removal from the mold.
[0256] The soft lozenge formulation may be provided as an individual unit weighing about 0.5 g to about 5 g, although embodiments of the present disclosure are not limited to such weights.
[0257] The curing time and temperature of the soft lozenge formulation can be varied as desired. In this regard, such variables can affect the final visual appearance of the soft lozenge formulation. For example, a long curing time and / or a low curing temperature can affect the final outer configuration or contour of the soft lozenge formulation. That is, the rate at which the product dries and / or hardens can affect the final properties of the product. In some instances, for example, by lowering the curing temperature and extending the curing time, the soft lozenge formulation can have a relatively smooth outer surface. In contrast, curing at a high temperature for a short time can result in the formulation appearing rough or wrinkled.
[0258] According to another aspect of the present disclosure, rather than using a mold to prepare the soft lozenge formulation, an extrusion process can be used in which the final soft lozenge formulation is extruded. In some examples, a soft lozenge composition in slurry form can be formed into a sheet and dried to a moisture content of, for example, about 15% to about 25% by weight to form a sticky or other paste-like material in a physically manageable form. The paste-like material can then be chopped or otherwise cut into small pieces, for example, using a mixer. The chopped material can then be extruded in an extrusion device into any desired shape / size, including shapes that may be difficult or impossible to achieve with a mold. In some examples, the extruded product can then be dried to achieve the desired moisture content. A similar process is described, for example, in U.S. Pat. No. 3,806,617 to Smylie et al., which is incorporated herein by reference in its entirety. Additionally, the soft lozenge composition can be subjected to a coextrusion process with another composition.
[0259] For example, shapes such as rods and cubes can be formed by first extruding the material through a die having the desired cross-section (e.g., circular or square), and then optionally cutting the extruded material to the desired length. Techniques and equipment for extruding tobacco feedstock are described in U.S. Patent No. 3,098,492 to Wursburg, U.S. Patent No. 4,874,000 to Tamol et al., U.S. Patent No. 2,488,018 to Graves et al., U.S. Patent No. 4,989,620 to Keritsis et al., U.S. Patent No. 5,072,744 to Luke et al., U.S. Patent No. 5,829,453 to White et al., and U.S. Patent No. 6,182,670 to White et al., each of which is incorporated herein by reference. Exemplary extrusion equipment suitable for use includes a food or gum extruder, or an industrial pasta extruder such as the Model TP200 / 300 available from Emiliomiti, LLC, Italy. In some instances, it may be possible to accomplish multiple steps of the methods described herein in a single machine, such as, for example, a kneading apparatus available from Buss AG.
[0260] The soft lozenge formulation can be provided in any suitable predetermined shape or form, most preferably in a form having a general shape such as a pill, pellet, tablet, coin, bead, ovoid, ellipsoid, or cube. The texture of the soft lozenge formulation preferably has a slightly chewable, dissolvable quality with a gentle elasticity or "bounce" upon chewing that gradually leads to greater flexibility during use. According to one embodiment, the soft lozenge formulation can preferably remain in the user's mouth for about 10 to 15 minutes until it is completely dissolved. Preferably, the formulation does not leave any residue in the user's mouth to a substantial extent and does not impart a smooth, waxy, or slimy feeling to the user's mouth.
[0261] According to some embodiments, the soft lozenge composition may be coated with a coating material after removal from the starch mold and before drying. For example, a glazing or anti-stick coating, such as CAPOL 410 (available from Centerchem, Inc.), may be applied to the soft lozenge composition to impart flowability. The coating composition may include, for example, an oil or wax, such as sunflower oil and / or carnauba wax.
[0262] The outer coating can also help improve the storage stability of the soft lozenge formulations of the present disclosure, as well as improve the packaging process by reducing friability and dusting. Equipment for applying the outer coating layer to the formulations of the present disclosure includes pan coaters and spray coaters, including Thomas Engineering's CompuLab 24, CompuLab 36, Accela-Cota 48, and Accela-Cota 60, among others. An example of an outer coating contains a film-forming polymer, such as a cellulose-based polymer, an optional plasticizer, and any flavor, color, salt, sweetener, or other additive described herein. The coating composition is typically aqueous in nature and can be applied using any pellet or tablet coating technique known in the art, such as pan coating. Examples of film-forming polymers include cellulose-based polymers such as methylcellulose, hydroxypropyl cellulose (HPC), hydroxypropylmethylcellulose (HPMC), hydroxyethyl cellulose, and carboxymethyl cellulose. Examples of plasticizers include aqueous solutions or emulsions of glyceryl monostearate and triethyl citrate.
[0263] In one embodiment, the coating composition comprises up to about 75 wt. % of a film-forming polymer solution (e.g., about 40 to about 70 wt. % based on the total weight of the coating formulation), up to about 5 wt. % of a plasticizer (e.g., about 0.5 to about 2 wt. %), up to about 5 wt. % of a sweetener (e.g., about 0.5 to about 2 wt. %), up to about 10 wt. % of one or more colorants (e.g., about 1 to about 5 wt. %), up to about 5 wt. % of one or more flavoring agents (e.g., about 0.5 to about 3 wt. %), up to about 2 wt. % of a salt such as NaCl (e.g., about 0.1 to about 15 wt. %), and the balance water. Exemplary coating compositions and application methods are described in U.S. Patent Application Serial No. 12 / 876,785, filed September 7, 2010, by Hunt et al., each of which is incorporated herein by reference.
[0264] While the above description focuses on a uniform composition throughout each dosage unit, a product can also be formed from multiple different formulations with different properties within the same dosage unit. For example, two different compositions can be filled into a single mold to produce a layered dosage form. Furthermore, two different compositions can be co-extruded to form a dosage form with different cross-sectional properties. Such a method can be used to provide a dosage form with two different compositions characterized by different dissolution rates, such that one portion of the dosage form dissolves at a first rate (e.g., a faster rate) and the second portion dissolves at a second, slower rate.
[0265] Method for preparing tablet formulations In some embodiments, the formulation is in the form of compressed pellets or tablets. In one embodiment, the method for making pellets or tablets involves first mixing the active ingredient with a bulk filler (e.g., EMDEX®). The remaining composition ingredients (e.g., sugar alcohol and any other desired ingredients such as binders, colorants, sweeteners, flavors, etc.) are then added. Optionally, the colorant can be added to one of the composition ingredients in a separate step before mixing with the remaining composition ingredients. Mixing of the composition can be accomplished using any mixing equipment. The final composition is then compressed into pellet or tablet form using conventional tableting techniques and optionally coated. Compressed pellets of the composition can be made by compressing the composition, including any relevant formulation ingredients, into pellet form and optionally coating each pellet with an overcoat material. Exemplary compaction equipment, such as compaction molding machines, are available from Vector Corporation as Colton 2216 and Colton 2247, and from Fette Compacting as 1200i, 2200i, 3200, 2090, 3090, and 4090. Equipment for applying outer coatings to compacted pelletized compositions is available from Thomas Engineering as CompuLab 24, CompuLab 36, Accela-Cota 48, and Accela-Cota 60.
[0266] If present, the coating typically comprises a film-forming polymer such as a cellulose-based polymer, an optional plasticizer, and any flavoring, coloring, salt, sweetener, or other additive described herein. The coating composition is usually aqueous in nature and can be applied using any pellet or tablet coating technique known in the art, such as pan coating. Examples of film-forming polymers include cellulose-based polymers such as methylcellulose, hydroxypropyl cellulose (HPC), hydroxypropylmethylcellulose (HPMC), hydroxyethyl cellulose, and carboxymethyl cellulose. Examples of plasticizers include aqueous solutions or emulsions of glyceryl monostearate and triethyl citrate. Additional coatings that can be used include food-grade shellac, waxes such as carnauba wax, and combinations thereof.
[0267] Method for preparing a lozenge formulation The methods and techniques used to formulate and manufacture the lozenge formulations described herein above can vary. For example, the compositions can be prepared by any method commonly used to manufacture hard-boiled confectionery. For example, exemplary methods for manufacturing hard candy can be found in LFRA Ingredients Handbook, Sweeteners, edited by Janet M. Dalzell, Leatherhead Food RA (December 1996), pages 21-44, which is incorporated herein by reference.
[0268] Typically, a first component mixture is prepared. The composition of the first component mixture can vary, but typically includes a sugar substitute and may contain various additional substances (e.g., sugar alcohol solution, NaCl, preservatives, additional sweeteners, water, and / or flavorings). In certain embodiments, the composition of the first component mixture includes a sugar substitute, salt, and vanillin. In other embodiments, the first mixture includes a sugar substitute and a sugar alcohol solution. Typically, the first component mixture does not contain an active ingredient, although in some embodiments, an active ingredient may be incorporated into the first component mixture.
[0269] The first component mixture is heated until melted, and then the mixture is heated to or past the hard crack stage. In confectionery, the hard crack stage is defined as the temperature at which a string-like strip of the heated mixture (obtained by pulling a cooled molasses sample between the thumb and index finger) becomes brittle or at which the molasses cracks when attempted to be molded. According to the present method, the temperature at which the hard crack stage is achieved may vary depending on the specific composition of the formulation mixture, but is generally between about 145°C and about 170°C. Typically, the mixture is not heated above about 171°C, the temperature at which caramelization begins to occur. In the method of the present disclosure, the mixture is typically cooled after being heated to or above the hard crack stage temperature. Heating can be performed at atmospheric pressure or under vacuum. Typically, the method of the present invention is performed at atmospheric pressure.
[0270] In one exemplary embodiment, the first component mixture includes a high percentage of isomalt, and the mixture is heated to about 143° C. Once all of the components have dissolved, the temperature is raised beyond the hard crack stage (e.g., to about 166° C.). After the mixture is heated to this temperature, heating is terminated and the mixture is allowed to cool.
[0271] In certain embodiments, the active ingredient(s) and optionally additional ingredients (e.g., additional sweeteners, fillers, flavors, and water) are individually combined in a second mixture. The second mixture is typically added to the first component mixture after the first component mixture has finished heating. In some embodiments, the addition of the second mixture may occur only after the heated first component mixture has cooled to a predetermined temperature (e.g., to about 132°C in certain embodiments). In certain embodiments, one or more flavors are added to the second mixture just before adding the second mixture to the heated first component mixture. Certain flavors are volatile, and therefore are preferably added after the mixture has cooled to a certain extent. The combined mixture is then formed into a desired shape. In certain embodiments, the mixture is poured directly into a mold, formed (e.g., rolled or pressed) into a desired shape, or extruded. If desired, the mixture can be extruded or injection molded. In certain embodiments, the mixture is formed into a mold of the desired shape or extruded in a closed system that requires low temperatures and can limit evaporation of certain mixture components. For example, such a system can limit evaporation of volatile ingredients, including, but not limited to, flavorings. Other methods of making lozenges are also intended to be encompassed herein.
[0272] Typical conditions associated with the manufacture of food-grade lozenge formulations as described herein include control of heat and temperature (i.e., the degree of heat to which the various ingredients are exposed during manufacture and the temperature of the manufacturing environment), moisture content (e.g., the degree of moisture present in the individual ingredients and in the final composition), humidity of the manufacturing environment, atmospheric control (e.g., nitrogen atmosphere), airflow experienced by the various ingredients during the manufacturing process, and other similar factors. Additionally, the various process steps involved in manufacturing the formulation may include selection of specific solvents and processing aids, use of heat and radiation, refrigeration and cryogenic conditions, ingredient mixing speed, etc. Manufacturing conditions can also be controlled by selection of the form (e.g., solid, liquid, or gas) of the various ingredients, the particle size or crystallinity of ingredients in solid form, the concentration of ingredients in liquid form, etc. The ingredients can be processed into the desired composition by techniques such as extrusion, compression, spraying, etc.
[0273] In certain embodiments, the lozenge formulation may be transparent or translucent. As used herein, "translucent" or "translucency" refers to a material that allows some light to pass through it diffusely. In certain embodiments, the lozenge formulations of the present disclosure may have a high degree of transparency, which may result in a material classified as "transparent" or exhibiting "transparency," which is defined as a material that allows light to pass freely through it without significant diffusion. The transparency of a lozenge formulation is in contrast to opacity, which refers to a material that cannot transmit light, and which exhibits some degree of translucency.
[0274] Transparency / translucency can be measured by any technique commonly used in the art, but is typically measured by spectrophotometric light transmittance over a wavelength range (e.g., about 400-700 nm). Optical techniques, such as turbidity (or scattered light measurement) and colorimetry, can also be used to quantify the turbidity (light scattering) and color (light absorption), respectively, of the lozenge formulations provided herein. Translucency can also be confirmed by visual inspection by simply holding a material (e.g., an extract) or formulation level with a light source and determining whether light diffusely passes through the formulation.
[0275] Method for preparing melt-type formulations In some embodiments, the formulation is in a meltable form. To prepare a meltable formulation, lipids are typically heated to just above their melting temperature so that the lipids are liquefied. Optionally, active ingredients, flavorings, and / or lecithin can be added to the liquefied lipid at this stage. All or part of the liquefied lipid can then be blended into the dry blend and mixed until the product reaches the desired homogeneity or until the desired texture characteristics are achieved. The mixture is milled (e.g., in a dry roll mill) until the particle size is less than about 20 microns. The milled isomalto-palm oil mixture is combined with any remaining lipids, and the dry ingredients and flavorings are mixed. The base is generally heated until a flowable consistency is achieved.
[0276] In some embodiments, a sugar alcohol (eg, isomalt) is added to a mixer bowl, and a portion of the total lipid (eg, melted palm oil) is added along with salt and an emulsifier.
[0277] Additional lipid is added with mixing until a cohesive clump forms. The clumped mixture is divided and transferred to a three-roll mill and processed to a particle size of less than 50 microns, or about 20 microns. The adjusted mixture is transferred to a mixer bowl and the remaining lipid is added with mixing. The mixture is warmed as needed to maintain fluidity.
[0278] The sweetener, flavoring, and active ingredient are added while mixing. Mixing is continued until a homogeneous composition is obtained. The mixture is allowed to stand for a period of time, for example, about 10-15 minutes. The composition can be divided into individual portions, for example, by pouring the composition into a sheet-like structure, cooling, and cutting the structure into individual portions, or by filling the composition into a mold and allowing it to cool. The mold can be starch or non-starch. In certain embodiments, the mold is non-starch.
[0279] The molten composition may be held in a mold (starch or non-starch) for a predetermined time, for example, about 1 to about 15 minutes, to cool and solidify the molten composition. Optionally, the mold containing the melt may be cooled by refrigeration to accelerate solidification.
[0280] According to another aspect of the present disclosure, rather than using a mold to prepare the melt formulation, an extrusion process can be used in which the final melt-type formulation is extruded as described herein above with respect to the soft-type lozenge extrusion method.
[0281] Method for preparing pouch-packaged oral preparations When the formulation is in the form of a pouch-packaged oral formulation, the method comprises: (a) combining active ingredients; (b) contacting the combination of active ingredients with at least one filler to obtain an oral dosage form; may include:
[0282] The combination of active ingredients may be as described herein above. The combination of active ingredients may also be as described below in connection with "Further Broad Aspects."

[0284] In some embodiments, step (b) comprises mixing the active ingredient combination with at least one filler. In some embodiments, the active ingredient combination is in solid form (e.g., powder form). The active ingredient combination may be mixed directly with the filler to obtain an oral formulation. In some embodiments, the active ingredient combination may be dissolved in a hydrophilic solvent (e.g., water and / or alcohol) before contacting with the filler. For example, the active ingredient combination may be dissolved in water or alcohol (e.g., ethanol or propylene glycol) before mixing with the filler. In such embodiments, the method may comprise a step of drying the product to remove the solvent. For example, the product can be dried by heating, freeze-drying, spray-drying, or simply by leaving the product at room temperature for a period of time. Preferably, the drying step comprises leaving the product at room temperature for 1 hour to 48 hours to remove the solvent.
[0285] The method may then further comprise the step of pouching the oral formulation using a pouch material as described herein above.
