Description

Composition for the prevention or treatment of periodontal disease and dental complex antibiotic ointment composition

[0001] The present invention relates to a composition for preventing or treating periodontal disease and a dental complex antibiotic ointment composition.

[0002] Periodontal disease is caused by bacterial infection in the gums, teeth, and implant areas due to poor oral hygiene. Periodontitis primarily affects natural teeth, while peri-implantitis occurs around dental implants. Severe periodontitis can lead to increased periodontal pocket depth, bleeding, gum erosion, and bone loss.

[0003] Peri-implantitis is similar to periodontitis, but unlike periodontitis, the lesion extends to the periapical region and presents with acute inflammatory symptoms. Furthermore, the oral microbiota distribution of periodontitis differs from that of periodontitis, leading to redness, swelling, mucosal hypertrophy, abscesses, bleeding, increased periodontal pocket depth, and increased bone loss at the implant site.

[0004] Although the symptoms of periodontitis and peri-implantitis differ, treatment methods can be divided into surgical and non-surgical, and similar approaches can be applied to each condition. Surgical treatments for periodontitis include gum incisions, scaling, and root planing to remove inflammation and plaque, and reshape the gingiva. For peri-implantitis, similar to periodontitis, inflammation is treated, and biofilm on the implant surface may be removed using lasers or nickel-titanium brushes. For both types of periodontal disease, bone grafting may be performed if necessary to restore lost gum bone.

[0005] Nonsurgically, both periodontitis and peri-implantitis are treated with antibiotics. Currently, antibiotic ointments containing minocycline hydrochloride are used for nonsurgical treatment. These ointments are injected into the periodontal pockets after removing calculus, plaque, and inflammation, directly injecting antibiotics. This provides a localized treatment. Numerous clinical trials have demonstrated the effectiveness of commercially available ointments in treating periodontitis.

[0006] However, in the treatment of peri-implantitis, it is difficult to treat all oral microorganisms for the symptom with the existing single-ingredient dental ointment, and there are pathological differences, so there are limitations in applying existing treatment drugs as a clear non-surgical treatment method for peri-implantitis, and it is necessary to seek a direction to apply other drugs.

[0007] Therefore, to address the problems of existing single-component antibiotic dental ointments, the present invention developed an antibiotic ointment composition combining two antibiotics. The present invention aims to provide a non-surgical treatment for periodontal diseases such as periodontitis and peri-implantitis more effectively than existing single-component dental ointments.

[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided to sufficiently convey the spirit of the present invention to those skilled in the art. The present invention is not limited to the embodiments presented herein and may be embodied in other forms. To clarify the present invention, the drawings may omit portions irrelevant to the description, and the sizes of components may be slightly exaggerated to facilitate understanding.

Furthermore, the singular forms "a," "an," and "the" as used herein include plural forms unless the context clearly dictates otherwise. Furthermore, the terms "comprise" and "include" as used herein specify a particular feature, region, integer, step, operation, element, or component, but do not exclude the addition of other features, regions, integers, steps, operations, elements, or components.

[0038] In the present invention, terms such as first, second, etc. are used to describe various components, and the terms are used only for the purpose of distinguishing one component from another.

[0039] Furthermore, the terminology used herein is merely for the purpose of describing exemplary embodiments and is not intended to limit the present invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In this specification, it should be understood that the terms "comprise," "include," or "have" indicate the presence of a feature, number, step, component, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, numbers, steps, components, or combinations thereof.

[0040] The present invention is susceptible to various modifications and takes various forms. Specific embodiments are illustrated and described in detail below. However, this is not intended to limit the present invention to specific disclosed forms, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0041]

[0042] Hereinafter, the composition for preventing or treating periodontal disease and the dental complex antibiotic ointment composition according to the present invention will be sequentially described in detail.

[0043] According to one embodiment of the present invention, the composition for preventing or treating periodontal disease comprises minocycline and metronidazole as active ingredients.

[0044] The above minocycline and metronidazole can be used as antibiotics for the prevention or treatment of periodontal disease. By using metronidazole in combination with the widely used minocycline, bacteria that single-ingredient antibiotics cannot treat can be treated.

[0045] For example, the minocycline may contain minocycline hydrochloride as an active ingredient, and the metronidazole may contain metronidazole benzoate as an active ingredient.

[0046] The above minocycline and the above metronidazole can be used in a mixed weight ratio of 1:1 to 1:25.

[0047] If the mixing ratio of the above minocycline and the above metronidazole is less than 1:1, the drug concentration is too low to have a therapeutic effect, and if it exceeds 1:25, there is a problem in terms of maintaining the properties in the ointment formulation.

[0048] The above metronidazole particle size (D90) may be 5 to 150 μm.

[0049] When the particle size of the metronidazole is less than 5㎛, the viscosity of the composition becomes too high, dispersion within the composition is not achieved well, and the composition clumps together, making it difficult to obtain the effect of the metronidazole. When the particle size exceeds 150㎛, the viscosity of the composition becomes low, and when a syringe nozzle of a standard applicable to a periodontal pocket (nozzle diameter 0.4 to 0.6 mm) is applied, there is a problem of clogging.

[0050] Preferably, the metronidazole particle size (D90) may be 5 to 100 μm, the metronidazole particle size (D90) may be 10 to 90 μm, and the metronidazole particle size (D90) may be 20 to 50 μm.

[0051] The density of the above metronidazole is 0.2 to 0.5 g / cm 3 It could be.

[0052] The density of the above metronidazole is 0.2 g / cm 3 If it is less than 0.5 g / cm, the viscosity of the composition or ointment is too high, and the spreadability is reduced when used as an ointment, and the density of the metronidazole is less than 0.5 g / cm. 3 If it is excessive, the viscosity is too low, so there is a problem that it does not spread when used as an ointment, does not adhere to the skin, and falls off.

[0053] The composition for preventing or treating periodontal disease of the present invention can be formulated in the form of an ointment.

[0054] According to one embodiment of the present invention, the dental composite antibiotic ointment composition comprises minocycline, metronidazole, a base, an emulsifier, a viscosity modifier, a stabilizer, and an antioxidant.

[0055] The above minocycline is used in a proportion of 0.1 to 2% by weight of the total weight of the ointment, and the above metronidazole can be used in a proportion of 0.1 to 50% by weight of the total weight of the ointment, and it is preferable to add them in an effective amount in order to exhibit an effective effect for preventing or treating periodontal disease.

[0056] The composition for preventing or treating periodontal disease of the present invention may use a base so that it can be formulated in the form of an ointment.

[0057] The above-mentioned base is used in a proportion of 5 to 25% by weight of the total weight of the ointment, and may include at least one selected from the group consisting of concentrated glycerin, polyethylene glycol 400, polyethylene glycol 4000, propylene glycol, 1,3-propanediol, isoprene glycol, pentylene glycol, hexylene glycol, butylene glycol, diethylene glycol, dipropylene glycol, diglycerol, erythritol, arabitol, adonitol, sorbitol, mannitol, xylitol, dulcitol, glucose, fructose, xylose, trehalose, maltose, saccharose, and lactose.

[0058] The above emulsifier is used in a proportion of 20 to 50% by weight of the total weight of the ointment, and may include at least one selected from the group consisting of glyceryl monostearate, glyceryl monooleate, glyceryl monolaurate, glyceryl monopalmitate, acetylated monoglyceride, white petrolatum, liquid paraffin, paraffin, stearic acid, cetostearyl alcohol, isopropyl myristate, and cetyl palmitate.

[0059] For example, the above-mentioned agent and the above-mentioned emulsifier can be mixed and used in a weight ratio of 1:1 to 1:4.

[0060] When the weight ratio of the base and the emulsifier is less than 1:1, the viscosity of the dental composite antibiotic ointment composition is too high, which causes a problem in that it cannot be dispensed through a syringe. When the weight ratio of the base and the emulsifier is more than 1:4, the viscosity is too low, which causes a problem in that it does not spread when used as an ointment, does not adhere to the skin, and falls off.

[0061] The viscosity modifier is used in a ratio of 1 to 20% by weight of the total weight of the ointment, and may include at least one selected from the group consisting of mineral oil, sesame oil, tea tree oil, avocado oil, castor oil, canola oil, coffee oil, corn oil, jojoba oil, kaya oil, linseed oil, macadamia oil, olive oil, peanut oil, rapeseed oil, cottonseed oil, rice bran oil, safflower oil, camellia oil, sunflower seed oil, soybean oil, shea butter, green tea seed oil, borage oil, walnut oil, evening primrose oil, lanolin oil, calendula oil, rosehip oil, coconut oil, mustard oil, palm olein oil, palm oil, palm kernel oil, apricot kernel oil, grape seed oil, castor oil, poppy seed oil, argan oil, flaxseed oil, almond oil, hazelnut oil, hempseed oil, and pumpkin seed oil.

[0062] The above stabilizer is used in a proportion of 1 to 8% by weight of the total weight of the ointment and may include magnesium chloride.

[0063] The above antioxidant is used in a proportion of 2% by weight or less of the total weight of the ointment, and may include ascorbyl palmitate.

[0064] The above composition may preferably be a pharmaceutical composition, and more preferably a composition having a formulation in the form of an ointment.

[0065] The composition may be provided as a pharmaceutical composition comprising the active ingredient alone or including one or more pharmaceutically acceptable carriers, excipients or diluents.

[0066] The term “pharmaceutically acceptable” as used herein means that the composition exhibits properties that are not toxic to cells or humans exposed to the composition.

[0067] Furthermore, the composition may be provided in combination with a conventionally known periodontal disease treatment agent. That is, the composition may be administered in combination with a known compound having a preventive or therapeutic effect on periodontal disease.

[0068] The above "administration" means introducing a given substance to an individual through an appropriate method, and "individual" means any animal, including rats, mice, livestock, etc., including humans, that has developed or may develop periodontal disease. A specific example may be a mammal, including humans.

[0069] The preferred dosage of the composition above varies depending on the patient's condition and weight, the severity of the disease, the drug form, the route of administration, and the duration of the administration, but can be appropriately selected by those skilled in the art. However, for a desirable effect, the composition is preferably administered at 0.01 to 1000 mg / kg / day, preferably 0.1 to 500 mg / kg / day, but is not limited thereto. The administration may be administered once a day or divided into several doses. The dosage is not limited in any way.

[0070]

[0071] Hereinafter, the present invention will be described in more detail through examples and experimental examples.

[0072] However, the following examples and experimental examples are only illustrative of the present invention, and the content of the present invention is not limited to the following examples and experimental examples.
