Description
CAPSULES FOR ORAL AND NASAL DELIVERY OF PHARMACEUTICALPRODUCTSCross Reference to Related Application(s)
[0001] The present application claims priority to U.S. Provisional Patent Application No. 63 / 545.340, filed on October 23, 2023. The entire contents of which are incorporated in its entirety.Technical Field of the Invention
[0002] The present invention relates to a method of administering a pharmaceutical composition. The method includes dispensing a pharmaceutical fill composition comprising an active agent from a softgel capsule to the nasal cavity' of a patient for nasal absorption or the oral cavity' of the patient for pre-gastric absorption.Background of the Invention
[0003] In the field of perfumery and cosmetics, it is common practice to distribute to the public free samples which contain a single-dose of the product in order to offer a chance to try the product. In addition, nutritional supplements or pharmaceutical agents in liquid carriers are also often distributed in single-dose containers. These single-dose forms have many advantages over other dosage forms such as bulk liquid preparations. For example, the content in a single-dose form can be individually fully identifiable and the integrity of the dosage form is protected until the actual moment of administration. If the content, e.g. cosmetics, nutritional supplements, pharmaceuticals, etc., is not used and the container is intact, the container may be retrieved and used with its integrity' preserved.
[0004] In the pharmaceutical industry, a softgel capsule can be used to deliver a pharmaceutical active ingredient. Softgel capsules are typically administered by swallowing the capsule whole via the oral route. However, some patients have difficulties swallowing the capsule whole.
[0005] Furthermore, supplying a pharmaceutical agent in a single-dose container allows accurate delivery' of a unit dose. This is important and advantageous when relatively small amounts of the pharmaceutical agent must be delivered. Additionally, some pharmaceutical active ingredients are required to be delivered to the buccal cavity or nasal cavity forlocalized action or buccal or nasal absorption. Such uniformity is more difficult to achieve via a tableting process where solids must be uniformly mixed and compressed, or via incorporation of the total dose of active ingredient into a bulk liquid carrier which then requires precise measurement of each dose prior to each administration. Thus, alternative ways of delivering the drug products are necessary' to meet the need of patients.
[0006] Single-dose cosmetics, nutritional supplements, or pharmaceuticals are traditionally packaged in small bottles with a removable stopper, a spray device, or in sachets with a tearable tab or with a line of weakness for delivering these products. These single-dose containers often need to be opened by tearing or twisting using one's hands. Such containers may be difficult to handle for some people in that they require two hands to open. In addition, many such containers that provide sprayable delivery are not biodegradable while many containers that are biodegradable do not provide sprayable delivery, which is advantageous for many applications.
[0007] Thus, there is a need to provide an alternative way to achieve the deliver}' of drug products orally, to buccal or nasal cavities and / or to deliver an active agent for pre-gastric absorption or buccal absorption, and eliminate the need for swallowing the whole capsule, improving the patient compliance.Summary of the Invention

[0036] The detailed description set forth below is intended to merely as a description of the presently preferred embodiments of the invention, and is not intended to represent the only form in which the present invention may constructed or utilized. The description sets forth the functions, means, and methods of implementing the invention in connection with the illustrated embodiments. It is to be understood, however, that the same or equivalent functions and features may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the claims.
[0037] As used herein, the singular forms “a,” 'an." and “the” include plural references unless the context clearly indicates otherwise. Thus, for example, reference to “a pharmaceutical active ingredient” includes a single pharmaceutical active ingredient as well as a mixture of two or more different pharmaceutical active ingredients, and reference to an “excipient” includes a single excipient as well as a mixture of two or more different excipients, and the like.
[0038] As used herein, the term “about” in connection with a measured quantity, refers to the normal variations in that measured quantity, as expected by one of ordinary skill in the art in making the measurement and exercising a level of care commensurate with the objective of measurement and the precision of the measuring equipment. In certain embodiments, theterm “about’' includes the recited number ±5%, such that “about 10” would include from 9.5 to 10.5.
[0039] Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context.
[0040] The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to illuminate certain materials and methods and does not pose a limitation on scope. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the disclosed materials and methods.
[0041] As used herein, the terms “active agent,” “active ingredient,” “active pharmaceutical ingredient,” “pharmaceutical active ingredient,” “API,” and “drug” refer to any material that is intended to produce a therapeutic, prophylactic, or other intended effect, whether or not approved by a government agency for that purpose. These terms with respect to specific agents include all pharmaceutically active agents, all pharmaceutically acceptable salts thereof, complexes, stereoisomers, crystalline forms, co-crystals, ether, esters, hydrates, solvates, and mixtures thereof, where the form is pharmaceutically active.
[0042] As used herein, the term “gastric absorption” refers to the absorption of an API in the stomach and intestines. For example, APIs formulated in enteric dosage forms such as tablets, capsules, or liquids are absorbed via gastric absorption. With gastric absorption, the API is absorbed from the intestines and brought directly into the liver, where it may be metabolized by hepatic enzymes into metabolites that are eliminated in the urine and / or feces. This elimination is referred to as “first-pass” metabolism or the “first-pass” effect in the liver and it can significantly reduce the bioavailability of an API.
[0043] As used herein, the term “pre-gastric absorption” refers to the absorption of an API into the portion of the alimentary canal before reaching the stomach, and includes nasal delivery (i.e., absorption via the nasal mucosa) and delivery’ to the oral cavity’ (i. e.. absorption via the buccal mucosa and / or the sublingual mucosa). Accordingly, an API that is delivered via pre-gastric absorption avoids first-pass metabolism and its harmful effects on the API’s bioavailability.
[0044] In an embodiment of the present disclosure, a method for administering a pharmaceutical composition to a patient is provided. Administering of the pharmaceutical composition includes dispensing a pharmaceutical fill composition including an active agentfrom a softgel capsule to the nasal cavity of a patient for nasal absorption or to the oral cavity of the patient for pre-gastric absorption.
[0045] In some embodiments, the pharmaceutical fill composition may be dispensed to the nasal cavity of the patient. In some embodiments, the pharmaceutical fill composition may be dispensed to the oral cavity of the patient. In some embodiments, the administering of the pharmaceutical composition bypasses first pass hepatic metabolism in the patient. In other embodiments, the pharmaceutical fill composition may be dispersed buccally or sublingually.
[0046] In some embodiments of the method, the softgel capsule may include a shell and the pharmaceutical fill composition. In some embodiments, the shell may include a shell composition including at least one gelling agent selected from a protein and a polysaccharide.
[0047] In some embodiments, the shell may include an area having a first shell thickness. The area having the first shell thickness may be oblong-shaped and have two protrusions that define a border. The shell may further include one or more areas of reduced shell thickness relative to the first shell thickness. The one or more areas of reduced shell thickness may be located within the border defined by the two protrusions. In some embodiments, the one or more areas of reduced shell thickness may be configured to rupture by exertion of a compression force on the oblong-shaped portion of the shell to provide an opening in the one or more areas of reduced thickness of the shell through which the pharmaceutical fill composition may be dispensed to the naval cavity or the oral cavity. The opening in the one or more areas of reduced thickness of the shell may be limited by the border defined by the two protrusions.
[0048] In some embodiments, the at least one gelling agent may be a protein-based gelling agent selected from the group consisting of collagen, gelatin, egg whites, and milk-based proteins. As used herein, “collagen” refers to a protein of connective tissue in animals. “Gelatin” refers to a translucent, colorless, odorless, brittle, nearly tasteless solid protein substance, derived from the collagen by partial hydrolysis. Generally, gelatin is classified into alkaline gelatin, acidic gelatin, or enzymatic gelatin. Alkaline gelatin is obtained from the treatment of collagen with a base such as calcium hydroxide. Acidic gelatin is obtained from the treatment of collagen with an acid such as hydrochloric acid. Enzymatic gelatin is generated from treatment of collagen with a hydrolase. In the context of the present disclosure, “gelatin” may also include substantially equivalent substances such as synthetic analogues of natural gelatin.
[0049] In some embodiments, the at least one gelling agent may be a polysaccharide-based gelling agent. The polysaccharide-based gelling agents may be commonly derived from aplant source, such as starch or cellulose. The polysaccharide-based gelling agent may be selected from cellulose or cellulose derivatives, such as microcrystalline cellulose, sodium carboxymethyl cellulose, methylcellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, and hydroxypropyl methylcellulose, starch and starch derivatives, pectin, gum, dextrins, alginates and carrageenans. Exemplary starches include arracacha starch, arrowroot starch, banana starch, barley starch, breadfruit starch, buckwheat starch, canna starch, cassava starch, colacasia starch, com starch, katakuri starch, kudzu starch, malanga starch, millet starch, oat starch, oca starch, pea starch, Polynesian arrowroot starch, potato starch, rice starch, rye starch, sago starch, sorghum starch, sweet potato starch, taro starch, water chestnut starch, wheat starch, yam starch, and mixtures thereof.
[0050] The starch of the present disclosure may be a modified starch. The term '’modified starch” refers to derivatives prepared by chemical treatment of starches, for example, acid treatment starches, enzyme treatment starches, oxidized starches, cross-bonding starches, and other starch derivatives. It is preferred that the modified starches be derivatized where their side chains are modified with hydrophilic or hydrophobic groups to thereby form a more complicated structure with a stronger interaction between side chains comparing with unmodified starches. Exemplary modified starch ethers and esters include carboxymethylated starch, hydroxypropylated starch, and hydroxypropylated carboxymethyl crosslinked starch.
[0051] “Modified starch ester” refers to a starch in which one or more of the hydroxyl groups have been reacted to form ester groups. The reaction usually involves a reaction to replace the hydrogen of the OH group on the starch with a -O-(C=O)-CH3 or -O-(C=O)-R group (where R is an aliphatic group).
[0052] “Modified starch ether” refers to a starch in which one or more of the hydrogens on the starch has been replaced by the carbon of an organic groups. For example methylation of a starch replaces the OH group with an OCH3 group.
[0053] The polysaccharide-based gelling agent may also be a gum. Exemplary' gums include acacia gum, agar, carrageenans, cassia gum, cellulose gum, furcellaran, gellan gum. guar gum. gum ghatti. karay a gum. larch gum, locust bean gum, pectin, plantago. tara gum, tragacanth, xanthan gum, or a combination thereof.
[0054] “Gum” refers to polysaccharides of natural origin, capable of causing a large viscosity increase in solution, even at small concentrations. They are used as thickening agents, gelling agents, emulsifiers, and stabilizers. Most often, these gums are found in the woody elements of plants or in seed coatings.
[0055] The polysaccharide-based gelling agent of the present disclosure may be pectin. "Pectin” refers to the complex set of polysaccharides that are present in most primary cell walls and particularly abundant in the non-woody parts of terrestrial plants. The characteristic structure of pectin is a linear chain of a-(l-4)-linked D-galacturonic acid that forms the pectin-backbone, a homogalacturonan. Into this backbone, there are regions where galacturonic acid is replaced by (l-2)-linked L-rhamnose. From the rhamnose residues, side chains of various neutral sugars branch off.
[0056] The pectin may include not only purified or isolated pectates, but also crude natural pectin sources, such as apple, citrus or sugar beet residues which have been subjected, when necessary, to esterification or de-esterification, e.g.. by alkali or enzymes. Preferably, the pectins used in this disclosure may be derived from citrus fruits such as lime, lemon, grapefruit, and orange.
[0057] The polysaccharide-based gelling agent may be dextrin. “Dextrin” refers to a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch or glycogen. Dextrin is a mixture of polymers of D-glucose units linked by a-(l - +4) or a-(l - +6) glycosidic bonds.
[0058] The polysaccharide-based gelling agent of the present disclosure may be alginate. “Alginate” refers to an anionic polysaccharide distributed widely in the cell walls of brown algae, where through binding with water, it forms a viscous gum. Alginate is a linear copolymer with homopolymeric blocks of (l-4)-linked -D-mannuronate (M) and its C-5 epimer a-L- guluronate (G) residues, respectively, covalently link together in different sequences or blocks. Its color ranges from white to yellow ish-brown. It is sold in filamentous, granular, or powdered fonris.
[0059] The polysaccharide-based gelling agent of the present disclosure may be a carrageenan. In some embodiments, carrageenan may provide particular advantages. "Carrageenan" refers to a family of polysaccharide gums extracted from red seaweed. They consist of linear sulfated high molecular weight polysaccharides made up of repeating galactose units and 3, 6 anhydrogalactose (3,6-AG), both sulfated and nonsulfated. The units are joined by alternating alpha 1-3 and beta 1-4 glycosidic linkages.
[0060] In some embodiments, the shell composition may include both a modified starch and iota-carrageenan. In an embodiment, the w eight ratio of the modified starch to the iota- carrageenan is at least about 1.5:1. or about 1.5:1 to about 4: 1, or from about 2: 1 to about 3: 1. A gel forming composition with the above weight ratio is capable of fusion, under pressure, in the range of about 207 kPa to about 2070 kPa (about 30 to about 300 psi) and attemperatures in the range of from about 25 to about 80 °C. In an embodiment, the capsule shell 5, according to the present disclosure, has a melting temperature of from about 2 to about 25 °C, from about 3 to about 15°C, or from about 4 to about 9 °C above its fusion temperature.
[0061] The iota-carrageenans may be conformed to the specification laid down by the USA and European regulatory authorities. The iota-carrageenan is not degraded and should conform to minimum viscosity standards, which correspond to a molecular weight of about 100K Daltons. Standardized iota-carrageenans are preferred. A particular preferred standardized iota- carrageenan is commercially available from the FMC Corporation of Princeton, N.J., known as VISCARIN® SD389, standardized with 15 % by weight dextrose. Other useful iota- carrageenans include a non-standardized iota-carrageenan from SKW BioSystems of Baupt, France known as XPU-HGI and a non-standardized iota- carrageenan from FMC.
[0062] The iota-carrageenan may be used in an amount that, in combination with the modified starch, effectively causes the gel forming compositions to have the required gelatin-like functional properties. As those skilled in the art will appreciate, the gel has what is known as a wet shell composition and a dry shell composition. The dry shell composition results from the evaporation or removal of w ater from the wet shell composition during the manufacturing process for making the softgel capsule. The dry shell composition may still contain some water. The amount of iota-carrageenan may range from about 6-12 % by w eight of the wet shell composition, about 7-12% by weight of the wet shell composition, 9-1 1% by w eight of the wet shell composition, or about 10% by weight of the et shell composition.
[0063] In some embodiments, the shell may be formed using one gelling agent. The one gelling agent may be gelatin. In some embodiments, the gelatin is mammalian gelatin. The shell may contain about 25% to about 45% by weight of gelatin. In some embodiments, the shell may include about 25% to about 40%, about 30% to about 45%, about 30% to about 40%, or about 30% to about 35%, based on weight of the shell composition. Such gelatin-based gel may be strong enough to survive manipulation in the encapsulation machine, provide good sealing properties at temperatures below the meltingpoint of the film, and have sufficient elasticity to allow for the formation of the softgel capsule.
[0064] The shell composition may further include at least one optional component selected from a plasticizer, a preservative, a flavoring agent, an opacifying agent, a buffer, an embrittlement inhibiting agent, a colorant, a disintegrant, a perfume, a flavoring, a shell texturing ingredient and / or pearlescent and / or glittering pigment, and water.
[0065] The plasticizers may include glycerol, polyglycerol, glycerin, propylene glycol, polyethylene glycol, xylitol, sorbitol, non-crystalizing solutions of sorbitol, glucose, fructose, and glucose syrups. These plasticizers may be used alone or in combination with each other. In a combination of plasticizers including glycerol, the glycerol typically comprises at least 30 % by weight of the combination, or in the range of about 30-70 % by weight. In some embodiments, the glycerol may be included in an amount of about 30% to about 70% by weight, about 35% to about 65%, about 40% to about 60%, or about 45% to about 55% by weight. An alternative combination may be ANIDRISORB (a proprietary mixture of Sorbitol, Sorbitans, Maltitol, and Mannitol, available from Roquette Freres). Other plasticizers may include saccharides and polysaccharides. The saccharides and polysaccharides suitable for use as a plasticizer herein may be produced by hydrolysis and / or hydrogenation of a simple or complex polysaccharides.
[0066] When a plasticizer is included, the plasticizer may be used in amounts of up to about 60 % by weight of the dry shell composition or up to about 30 % by weight of the wet shell composition used to make the softgel capsule. In some embodiments, the compositions may include a plasticizer in an amount of about 10 % to about 25 % by weight, about 12% to about 22% by weight or about 15% to about 20% based on the weight of the wet shell composition and from about 30 % to about 50 % by weight, about 35% to about 50% by weight, or about 40% to about 45% of the dry shell composition.
[0067] In some embodiments, the shell composition may include a preservative. Preservatives may be antimicrobial preservatives, which inhibit the growth of microbes, or an antioxidant, such as oxygen absorbers, which inhibit the oxidation of the pharmaceutical fill composition within the softgel capsule. Common antimicrobial preservatives include sorbic acid and its salts, benzoic acid and its salts, calcium propionate, sodium nitrite, sulfites (sulfur dioxide, sodium bisulfite, potassium hydrogensulfite, etc ), and disodium ethylenediaminetetraacetic acid (EDTA). Antioxidants may include butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), tert - butylhydroquinone (TBHQ) and propyl gallate. Other preservatives include ethanol and methylchloroisothiazolinone.
[0068] In some embodiments, the shell composition may further include an embrittlement inhibiting agent. The embrittlement inhibiting agent may include a mixture of sorbitol and one or more sorbitans.
[0069] In some embodiments, a buffer system may be used in the shell composition. The buffer system may include a phosphate buffer.
[0070] In some embodiments, the shell composition may include a plant-based gelling agent. In some embodiments, the shell composition including a plant-based gelling agent includes one or more of carrageenan, starch, pullulan, a plasticizer, water and maltodextrin. In some embodiments, carrageenan may be included in an amount of about 3 to about 20 wt%, about 5 to about 15 wt%, or about 8 wt% to about 12 wt%, based on weight of the wet shell composition. In some embodiments, starch may be included in an amount of about 10 to about 40 wt%, about 15 to about 35 wt%, or about 20 to about 30 wt%, based on weight of the wet shell composition. In some embodiments, pullulan may be included in an amount of about 5 to about 50 wt%, about 10 to about 45 wt%, about 15 to about 40 wt%, or about 20 to about 35 wt% based on weight of the wet shell composition.

[0102] Referring now to the Figures, FIG. 1 illustrates a softgel capsule according to an embodiment of the present disclosure. In FIG. 1, a softgel capsule 100 includes a capsule shell 5. The capsule shell 5 includes one or more areas of reduced thickness 3 that enable opening of the softgel capsule 100 by compressing the softgel capsule 100 to cause rupture of the capsule shell 5 at the one or more areas of reduced thickness 3. A fdl contained in the softgel capsule 100 can be reliably dispensed from the softgel capsule 100 via the one or more ruptured areas of reduced thickness 3 by being sprayed or squeezed out of the capsule shell 5 to an intended dispensing location, such as the oral cavity or the nasal cavity.
[0103] The capsule shell 5 of the softgel capsule may be impermeable to the fill therein, but could be permeable to other solvents, such as water. The softgel capsule 100 may provide a single-dose product and is small in size. The volume of the softgel capsule 100 may be from about 0.05 mL to about 5 mL, from about 0. 1 mL to about 3 mL, about 0.2 to about 2 mL, or about 0.25 mL to about 1 mL.
[0104] The softgel capsule 100 may have a variety of shapes including spheres, oblong shapes, elongated tubes, disks, squares, rectangles, cylindrical shapes, ellipsoidal shapes, cat ear shapes, or other geometrical shapes. The softgel capsule 100 may also have shapes that are customized for a specific product or vender.
[0105] The one or more areas of reduced thickness 3 may be located any where on the capsule shell 5. In some embodiments, the area of reduced thickness may be offset from the center of the capsule shell 5 to provide a large portion of the capsule shell 5 that can be compressed to rupture the area of reduced thickness 3. In some embodiments, the area of reduced thickness 3 may be located at an end or a comer of the softgel capsule 100 where the softgel capsule 100 has an end or a comer (such as rectangular shape or spheroidal shape, Figure 1). In some embodiments, two areas of reduced thickness 3, or three areas of reduced thickness 3, or four or more areas of reduced thickness, may be provided as a cluster on thecapsule shell 5. The plurality of areas of reduced thickness 3 may be used to provide a spray of plurality of streams of the fill when dispensed from the softgel capsule 100 that might be useful when spreading the fill over an area is desired.
[0106] In Figure 3D, a cat ear shaped softgel capsule 100 is illustrated. The cat ear shape softgel capsule 100 of Figure 3D may include an air hole located in a central area of the capsule 100. In a preferred shape, the area of reduced thickness 3 is a decreased land or surface area bounded by two protrusions 2 such as in the cat ear shape shown in Figure 3D. The land or surface area may be decreased in the sense that the protrusions 2 define borders of the land or surface area within which the area of reduced thickness 3 may be located, thereby decreasing the potential size of an opening created by exerting pressure on the area of reduced thickness 3, relative to a similar package without the protrusions 2. These two protrusions 2 stabilize the fill material in the capsule and create a back pressure directly on the area of reduced thickness 3. The pressure may rupture the area of reduced thickness 3 to express the fill material. The area of reduced thickness 3 also provides a specific start point for the expression, as well as fanning the fill material between the two protrusions 2.
[0107] The walls of the softgel capsule may be shaped, as shown in Fig. 3D. to help direct compressive force applied to the softgel capsule 100 to the area of reduced thickness 3 to facilitate both opening the capsule 100 and dispensing of the contents of the capsule 100, particularly for spray dispensing to an oral cavity or nasal cavity.
[0108] The area of reduced thickness 3 may be a dot. a line, or multiple lines that are parallel or intersecting as shown in Figures 3A-3D. In some embodiments, the area of reduced thickness 3 may have a shape such as fantasy shapes, animals, flowers, a sun, other natural patterns or portions thereof, preferably located in a decreased land area between two protrusions 2, where the two protrusions 2 have the shape of, for example, ears, tails, hands, noses and the like. The area of reduced thickness may be of different lengths or widths in order to customize the rate or pattern of dispensing of the fill from the softgel capsule 100.
[0109] The area of reduced thickness 3 may be more fragile than the remainder of the capsule shell 5 and thus may preferentially ruptured when a sufficient compression force is applied to the softgel capsule 100. The pressure may be applied via hand or finger pressure such as by squeezing the package. The pressure may also be applied by a device designed for use with the softgel capsule of the invention such as a small appliance provided with structure that can exert a compressive force on the softgel capsule 100. The appliances may be able to squeeze the capsule 100 following an established rhythm / path to provide the desired dispensing from capsule 100.
[0110] The ruptured area of reduced thickness 3 may become an ejection orifice for the fill of the softgel capsule 100 which provides a channel through capsule shell 5 for dispensing the fill. The fill may be dispensed as a spray and / or by squeezing the fill from the softgel capsule 100 in a predetermined direction. The fill may be sprayed or squeezed into the oral cavity or nasal cavity7.
[0111] In an embodiment, the softgel capsule 100 may be in the form of an oblong / tear shape. In this embodiment, the application of pressure on the sides where the sealing line resides provides an excellent spray effect. In addition, this embodiment is easy to use and facilitates control of the spray effect. The extended radius on each side of the break point causes the fill material to find the center location during application of pressure. The area of reduced wall thickness 3 enhances the break and allows fill material to express at the center point. The area of reduced thickness 3 may be sized to provide a desired dispensing such as a fine spray.
[0112] In some embodiments, the softgel capsule 100 may have a main body 1 and a protrusion 2 as shown in Figure 2. The main body 1 may have any shape such as a shape of a sphere, a spheroidal shape, an ellipsoidal shape, a rectangular shape, a cylindrical shape or a cubic shape. The protrusion 2 extends, preferably radially outwardly, from the main body 1. The protrusion 2 may be any shape such as a bulge, a cylindrical protrusion, a finger-like shape, or in the form of a likeness of an ear, tail, hand, nose, and the like. In some embodiments, the protrusion 2 may extend less than about 0.5 mm, or less about 0.4 mm, or less than about 0.3 mm, or less than about 0.2 mm from the main body 1 .
[0113] The area of reduced thickness 3 may be located on the protrusion 2. The user may compress the main body 1 of softgel capsule 100 in order to rupture the area of reduced thickness 3 on the protrusion 2. Placing the area of reduced thickness 3 on the protrusion 2, at the tip or in a decreased land area of protrusion 2, may offer convenience for dispensing the fill to certain locations such as inside of the ears, nose, or mouth. The protrusions help direct the fill to flow to the location of the area of reduced thickness 3 in order to facilitate dispensing and, in some embodiments, to help focus the exertion of pressure on the area of reduced thickness 3 to facilitate opening the softgel capsule 100.
[0114] In some embodiments, a plurality of protrusions 2 may be present on the softgel capsule 100 each with an area of reduced thickness 3. In some embodiments, the softgel capsule 100 may have two protrusions 2 where the area of reduced thickness 3 is located in a decreased land area between the two protrusions 2. The plurality of protrusions 2 may form a cluster on the softgel capsule 100. In some embodiments, plurality of protrusions2 with plurality of areas of reduced thickness 3 may provide a plurality of dispensing streams when it is desirable to spray the fill out of the softgel capsule 100 over a relatively large area.
[0115] Optionally, at least a portion of the surface of the capsule shell 5 may be textured by providing textured areas 4 as shown Figure 2. The texturing may be provided by, for example, a raised pattern on the surface of the softgel capsule 100 such as ridges, stripes, bars, bands, streaks, strips, spots, striations, ribs, and combinations thereof, and combinations thereof. This texturing may be applied to capsule shells that comprise gelatin. The texturing may also be provided by one or more indentations in the surface of the softgel capsule 100 of any suitable size or shape though care must be taken not to create an area of weakness that could rupture during compression. A user may hold and compress the softgel capsule 100 at the textured areas 4 for ease of handling and / or to improve grip on the softgel capsule 100 during compression of the softgel capsule 100 for dispensing. The texture 4 may be preferably imparted to the softgel capsule 100 during the manufacturing process by, for example, use of a die that provides texture to the film used to form the capsule shell 5.
[0116] The softgel capsule shell 5 of the softgel capsule 100 may be formed from at least one gelling agent. In some embodiments, the softgel capsule shell 5 may be formed from a combination of two gelling agents.

[0117] Specific embodiments of the invention will now be demonstrated by reference to the following examples. It should be understood that these examples are disclosed solely by way of illustrating the invention and should not be taken in any way to limit the scope of the present invention.
[0118] An example of the softgel capsule as described herein will now be described. It is understood that the example is an illustrative example and is not meant to be limiting.
[0119] The softgel capsules of the present disclosure are used as a container to deliver a pharmaceutical or nutraceutical products to oral and nasal cavity or to skin surface. The capsules were manufactured in a way to create a weak spot created on the tip of thecapsule while ensuing the capsule staying intact during normal storage. During administration of the pharmaceutical composition, the content of the capsule may be delivered to the intended location, either the oral cavity or the nasal cavity by squeezing the capsule. Upon squeezing, the tip of the capsule will burst and release the content of the softgel capsule. The shell can then be discarded as biodegradable waste.
[0120] In Table 1, a shell composition to form a shell of the softgel capsule including a plant based shell is shown.Table 1 : Plant-based Shell Composition
[0121] In Table 2, a shell composition to form a shell of the softgel capsule including gelatin is shown.Table 2: Gelatin-based Shell Composition
[0122] The fill material may include a prescription or over the counter druge product, nutraceutical product that is both hydrophobic or hydrophilic in nature. The manufacturing steps for preparing the softgel capsules as described herein are as follows:1. Gel mass preparation is performed using a gel melter. All excipients for the gel mass are mixied at elevated temperatures of 60 to 95 C to dissolve the solid excipients and form a homogenous flowable gel mass.2. The fill material containing the drug substance is dissolved or suspended in solvents or suspending liquid with mixing. The fill is then deaerated to remove air.3. A rotary die encapsulation machine is employed to encapsulate the fill material. Specially designed dies are used to create the weak spot on the tip of the capsule during the capsule sealing process. This may be achieved where the cutting edge is made thinner than the rest of the die.4. The wet capsules are dried, inspected and packaged into bulk cartons.5. Finished capsules are packaged into bottles or blisters.Fill Weight Study
[0123] A study was performed to test the fill weight of the softgel capsule after dispensing the pharmaceutical composition. In Table 3, the results of the study are shown. In the standard operating procedure, a whole softgel capsule including the fill material was weighed. Then, the fill material was discarded, and the shell was cleaned using solvent. The softgel capsule was then re-weighed. The difference between the whole capsule and the shell weight is calculated as the fill weight.Table 3: Fill Weight of SOP study
[0124] A study was performed to test the delivered fdl quantity of the softgel capsule after squeezing the softgel capsule. In Table 4, the results of this study are shown. In the squeeze test, the whole softgel capsule including the fill material was weighed. The fill material was then squeezed out, where the leftover shell without any cleaning is reweighed. The difference between the whole capsule weight and the shell weight is the amount of fill material discharged.Table 4: Fill Weight of Squeeze testForce Required to Squeeze the Fill Out of Capsule
[0125] A study was performed to investigate the relationship between the force required to squeeze the fill out of capsule and capsule hardness and water activity. The force required to squeeze the fill out of capsule was measured as the burst strength using a Texture Analyzer. The capsule hardness was determined using a hardness tester. The water activity was measured using a water activity meter. Table 5 summarizes the study results.Table 5. Force Required to Squeeze the Fill Out of Capsule as Function of Capsule Hardness and Water ActivityP 2,1 | 0,4775 | 9,756 |
[0126] From this study, the harder the capsule was, and the lower the water activity was, the higher force (burst strength) was required to squeeze out the fill content.
