Description

【0001】
【発明の属する技術分野】
本発明は抗う蝕性で、のどや口腔内等において優れた殺菌効果を示す固形製剤に関する。
【0002】
【従来の技術】
従来から、鎮咳去痰剤、殺菌剤、消炎剤等を薬効成分としたドロップ剤やトローチ剤が広く販売されている。これらのほとんどはショ糖を基剤とするが、一部には抗う蝕性や低カロリーを目的とした糖アルコールを基剤とするものがある。
【0003】
抗う蝕性の糖アルコール基剤の固形製剤であっても口腔内で溶解させたときのpHが5.5以下になるとエナメル質脱灰を生じ、pHが8以上では粘膜を刺激するようになる。よって固形製剤では口腔内で溶解した時のpHは5.5〜8.0の範囲が好ましいが、嗜好性や防腐性を高めるために加える酸味料などの作用により、pH値は5.5以下になるのが通常である。
【0004】
固形製剤は口腔内でゆっくり溶解しながら長時間滞留するので、殺菌剤を配合すると効果的に殺菌できる。なかでも、カチオン系殺菌剤は吸着性に優れ、強い殺菌力を有するため、プラーク形成抑制作用が高く、う蝕、歯周病、口臭等の口腔疾患の治療及び予防に有用であるが、カチオン性殺菌剤は他成分との相互作用による不活性化が起こりやすく、固形製剤において、その有効性(殺菌力)が充分に発揮しにくいといった課題がある。
【0005】
カチオン性殺菌剤の殺菌力が固形製剤中で不活性化される原因の1つはアニオン成分との相互作用であり、具体的には、粘結剤やpH調整剤等に含まれるアニオン成分とのコンプレックス形成や、ステアリン酸マグネシウム等のような滑沢剤への吸着がおこり不活性化する。また、主にドロップ剤を製造する際に消泡目的で配合されるノニオン性界面活性剤によるミセルへのとりこみがおこりやすく、その有効性が充分に発揮されていないことが多い。しかし、のどや口腔内で用いる殺菌消毒用固形製剤においてカチオン性殺菌剤の不活性化を防ぐための製剤上の工夫は特許上も製品上も見当たらない。
【0006】
特許第2712113号公報には水素化イソマルツロース(還元パラチノース)を基剤とするロゼンジ糖剤が開示されているが、特にカチオン性殺菌剤の不活性化についての記載はない。また、特開2000−327563号公報には、薬効成分の保存安定性を満足させるために、還元パラチノースの結晶層で被覆し、防湿性を高めたドロップ剤が開示されている。しかし、防湿性を高めることによって、経時的な薬効成分の変化を防ぐことはできるが、元々薬効成分の活性が不活性化しているか否かとは無関係である。
【0007】
【発明が解決しようとする課題】
本発明の目的は、抗う蝕性で、かつカチオン性殺菌剤の殺菌活性が充分に発揮される固形製剤を提供することである。
【0008】
【課題を解決するための手段】
本発明者らはかかる事情に鑑み鋭意研究を行った結果、カチオン性殺菌剤と糖アルコールを配合した固形製剤において、組成物を30w/v%水溶液にしたときのpHを5.5〜8.0の範囲になるように調整した場合、エナメル質が脱灰されないために抗う蝕性で、かつ全組成中のアニオン成分及びノニオン界面活性剤の合計配合量がカチオン性殺菌剤の配合量に対して3重量倍以下の場合、殺菌活性が不活性化されないことを見出し、本発明を完成するに至った。
【0009】
【発明の実施の形態】
本発明で用いるカチオン性殺菌剤は、特に限定するものではないが、ビスビグアニド化合物や第4級アンモニウム塩などであり、より具体的にはグルコン酸クロルヘキシジン、塩酸クロルヘキシジン、塩化セチルピリジニウム、塩化ベンゼトニウム、塩化ベンザルコニウム、塩化デカリニウムなどが挙げられる。これらカチオン性殺菌剤は、1種または2種以上を組み合わせて配合することができ、その配合量は、殺菌力の閾値および安全性を考慮すると、固形製剤全量に対して、0.005〜5重量%、特に0.01〜0.5重量%が好ましい。

【0014】
本発明の固形製剤は、その30w/v%水溶液においてpHを5.5〜8.0とする。pHが5.5未満ではエナメル質の脱灰がおこるためう蝕の原因となり、8.0を超えると製剤の味が損なわれる。pH調整が必要な場合、クエン酸、コハク酸、リン酸、リンゴ酸、酢酸、乳酸、フマル酸、マレイン酸及びこれらの塩から選んだ有機酸およびその塩を、本発明の固形製剤を30w/v%水溶液にしたときのpHが5.5〜8.0の範囲になるように、1種または2種以上を組み合わせて適宜調整する。その配合量は組成物全体に対して、0.1重量%を超えない量で達成できる。
【0015】
本発明の固形製剤は、口腔内およびのどを殺菌するものであればよく、トローチ剤、タブレット剤、ドロップ剤、あるいは、グミなどの硬度の低い固形飴など、常法により製せられ提供される。
【0016】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a solid preparation which is carious and has an excellent bactericidal effect in the throat and the oral cavity.
[0002]
[Prior art]
2. Description of the Related Art Drops and lozenges containing a cough expectorant, a bactericide, an anti-inflammatory agent or the like as a medicinal component have been widely sold. Most of these are based on sucrose, but some are based on sugar alcohols for anti-cariogenicity and low calorie.
[0003]
Enamel demineralization occurs when the pH when dissolved in the oral cavity is 5.5 or less, and the mucous membrane is stimulated when the pH is 8 or more, even in the case of a solid preparation of an anti-cariogenic sugar alcohol base. . Therefore, in the case of a solid preparation, the pH when dissolved in the oral cavity is preferably in the range of 5.5 to 8.0, but the pH value is 5.5 or less due to the action of an acidulant added to enhance palatability and preservability. Is usually the case.
[0004]
Since the solid preparation stays for a long time while slowly dissolving in the oral cavity, it can be effectively sterilized by adding a bactericide. Among them, cationic bactericides have excellent adsorptivity and strong bactericidal activity, so they have a high plaque formation inhibitory effect, and are useful for the treatment and prevention of oral diseases such as dental caries, periodontal disease and bad breath. The bactericidal fungicide has a problem in that it tends to be inactivated due to interaction with other components, and it is difficult to sufficiently exert its effectiveness (bactericidal power) in a solid preparation.
[0005]
One of the causes that the bactericidal power of the cationic bactericide is inactivated in the solid preparation is an interaction with an anionic component. Complex formation and adsorption to lubricants such as magnesium stearate, etc., and inactivate. In addition, nonionic surfactants incorporated for the purpose of defoaming are mainly liable to be incorporated into micelles when producing a dropping agent, and their effectiveness is often not sufficiently exhibited. However, in the solid preparation for sterilization and disinfection used in the throat and the oral cavity, there is neither a patent nor a product in the preparation for preventing the inactivation of the cationic germicide.
[0006]
Japanese Patent No. 2712113 discloses a lozenge sugar agent based on hydrogenated isomaltulose (reduced palatinose), but does not specifically describe inactivation of a cationic fungicide. Japanese Patent Application Laid-Open No. 2000-327563 discloses a dropping agent coated with a reduced palatinose crystal layer to improve the moisture resistance in order to satisfy the storage stability of a medicinal component. However, by increasing the moisture-proof property, it is possible to prevent the medicinal component from changing over time, but it is irrelevant whether or not the activity of the medicinal component is originally inactivated.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to provide a solid preparation which is anticariogenic and has sufficient bactericidal activity of a cationic bactericide.
[0008]
[Means for Solving the Problems]
The present inventors have conducted intensive studies in view of the above circumstances, and as a result, in a solid preparation containing a cationic bactericide and a sugar alcohol, the pH of the composition in a 30 w / v% aqueous solution was adjusted to 5.5 to 8.0. When adjusted to be in the range of 0, since the enamel is not demineralized, it is anti-cariogenic, and the total blending amount of the anionic component and the nonionic surfactant in the entire composition is relative to the blending amount of the cationic bactericide. When the weight is 3 times or less, it was found that the bactericidal activity was not inactivated, and the present invention was completed.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Cationic bactericides used in the present invention are not particularly limited, but include bisbiguanide compounds and quaternary ammonium salts, and more specifically, chlorhexidine gluconate, chlorhexidine hydrochloride, cetylpyridinium chloride, benzethonium chloride, Examples include benzalkonium chloride and decalinium chloride. These cationic bactericides can be used alone or in combination of two or more. The amount of the cationic bactericide is 0.005 to 5 with respect to the total amount of the solid preparation in consideration of the threshold of bactericidal activity and safety. % By weight, particularly preferably 0.01 to 0.5% by weight.
[0010]
The sugar alcohol used in the present invention is not particularly limited. For example, reduced starch syrup, erythritol, xylitol, sorbitol, maltitol, lactitol, reduced palatinose, mannitol, reduced oligosaccharide and the like are preferable. These sugar alcohols can be used alone or in combination of two or more, and the compounding amount is at least 80% by weight, particularly preferably 85 to 99% by weight, based on the total amount of the solid preparation.
[0011]
The anion component used in the present invention is not particularly limited. For example, an organic acid as a pH adjuster, saccharin sodium as a high-intensity sweetener, acesulfame potassium, dipotassium glycyrrhizinate, a binder or a disintegrant Gum arabic, tragacanth gum, sodium alginate, xanthan gum, carrageenan, sodium polyacrylate, sodium carboxymethylcellulose, pectin, gelatin, talc as a lubricant, stearate, magnesium silicate, sodium copper chlorophyllin as a coloring agent, etc. No.
[0012]
The nonionic surfactant used in the present invention is not particularly limited, and examples thereof include sucrose fatty acid esters, glycerin fatty acid esters, polyglycerin fatty acid esters, propylene glycol fatty acid esters, and polyoxyethylene hydrogenated castor oil.
[0013]
In the present invention, the total amount of the (C) anionic component and the nonionic surfactant is not more than 3 times by weight of the compounding amount of the (A) cationic bactericide, that is, the solid preparation is converted from the compounding amount of the (A) cationic bactericide. It is 0.015 to 15%, more preferably 0.03 to 1.5% based on the total amount. If the amount exceeds 3 times by weight, the bactericidal activity of the cationic bactericide is inactivated.
[0014]
The solid preparation of the present invention has a pH of 5.5 to 8.0 in a 30% w / v aqueous solution. If the pH is less than 5.5, enamel is demineralized, causing caries. If the pH is more than 8.0, the taste of the preparation is impaired. When pH adjustment is necessary, an organic acid and its salt selected from citric acid, succinic acid, phosphoric acid, malic acid, acetic acid, lactic acid, fumaric acid, maleic acid and salts thereof are added to the solid preparation of the present invention at 30 w / One type or a combination of two or more types is appropriately adjusted so that the pH of the v% aqueous solution is in the range of 5.5 to 8.0. The compounding amount can be achieved in an amount not exceeding 0.1% by weight based on the whole composition.
[0015]
The solid preparation of the present invention may be any one that can sterilize the oral cavity and throat, and is provided by a conventional method such as a lozenge, tablet, drop, or solid candy with low hardness such as gummy gum. .
[0016]
In order to make the solid preparation of the present invention into a desired shape, a pharmaceutically active ingredient other than a sweetener, a binder, a disintegrant, a lubricant, a colorant, a flavor, and a cationic bactericide can be appropriately compounded. However, when the anionic component and the nonionic surfactant are blended in order to sufficiently exhibit the bactericidal activity in the solid preparation of the present invention, the total amount thereof is 3 times by weight the amount of the cationic bactericide. Must be:
[0017]
When the sweetness of the solid preparation of the present invention is insufficient, it is preferable to supplement with a sweetener other than sucrose. Specifically, polysaccharides such as disaccharides or more (maltose, xylose, isomerized sugars such as palatinose and trehalose, etc.), high-intensity sweeteners (in addition to the components described as the aforementioned anionic components, stevioside, sucralose, thaumatin, etc.) ) And the like.
[0018]
Examples of the binder and disintegrant include locust bean gum, guar gum, methylcellulose, polyvinyl alcohol, polyvinylpyrrolidone, hydroxypropylcellulose, hydroxyethylcellulose, and the like, in addition to the components described above as the anionic component.
[0019]
Examples of the lubricant include sucrose fatty acid esters that are also nonionic surfactants, in addition to the components described as the anion component.
[0020]
Examples of the coloring agent include, in addition to the components described as the above-described anionic components, tar dyes, titanium oxide, caramel, redwood, gardenia, safflower, carotenoids, red cabbage dyes, and the like.
[0021]
In the solid preparation of the present invention, a medicinal ingredient other than the cationic bactericide can be blended. Specifically, an antitussive expectorant, a bactericidal disinfectant, an anti-inflammatory agent, a single or two or more selected from vitamins, etc. Is used.
[0022]

[Table 1]
Figure 2004026725
[0026]
As is clear from the results in Table 1, the compounding amount of the anionic component and the nonionic surfactant in all the components was 3% by weight or less with respect to the compounding amount of the cationic bactericide chlorhexidine hydrochloride, and a 30 w / v% aqueous solution was used. Examples 1-4 having a pH of 5.5-8.0 exhibited higher bactericidal activity. On the other hand, in Comparative Example 1, although the pH was 5.8, the compounding amount of the anionic component and the nonionic surfactant in all the components exceeded 3 times by weight with respect to the compounding amount of chlorhexidine hydrochloride, and the bactericidal activity was increased. Had been inactivated. In Comparative Example 2, the blending amounts of the anionic component and the nonionic surfactant in all components were 3 times by weight or less, and the bactericidal activity was maintained, but the pH was as low as 4.3, and enamel demineralization was likely. And was unsuitable for anti-carious use. In Comparative Examples 3 and 4, the blending amounts of the anionic component and the nonionic surfactant in all the components exceeded 3 times by weight, and the bactericidal activity was inactivated. Further, in Comparative Example 3, enamel demineralization was likely due to the low pH as in 2, and in Comparative Example 4, the pH exceeded 8.0, and the taste was poor.
