Description

本発明は、グルコサミン類を配合した固形製剤に関する。   The present invention relates to a solid preparation containing glucosamines.

グルコサミン類は主にカニやエビ等が有するキチン質を分解することにより精製されるアミノ糖であり、変形性関節炎等の鎮痛作用及び症状の改善 、美肌効果、血流改善効果等が得られることが報告されており、かかる効果が期待される医薬品や食品等における成分としての需要が急増している。   Glucosamines are amino sugars that are purified by degrading chitin mainly contained in crabs and shrimps, etc., and analgesia such as osteoarthritis and improvement of skin condition, blood flow improvement and the like can be obtained Have been reported, and the demand as an ingredient in pharmaceuticals and foods etc. for which such effects are expected is rapidly increasing.

グルコサミン類、特にグルコサミン塩酸塩は独特の呈味があるため、固形製剤として提供する場合、独特の呈味をマスキングした製剤であることが好まれる(特許文献1を参照)。しかしながら、グルコサミンを酸味料であるクエン酸等の有機酸及び賦形剤である糖アルコールと共に配合した場合、保存中に黄褐色に変色してしまい、製品の品質を維持できないという課題があった。   Since glucosamines, in particular glucosamine hydrochloride, have unique taste, when provided as a solid preparation, it is preferred that the preparation has a unique taste masking (see Patent Document 1). However, when glucosamine is compounded with an organic acid such as citric acid which is an acidulant and a sugar alcohol which is an excipient, it has a problem of being discolored to yellowish brown during storage, and the quality of the product can not be maintained.

特開2002−125638号Japanese Patent Application Laid-Open No. 2002-125638

本発明は、グルコサミン類、有機酸、糖アルコールの同時配合により生じる経時的変色を抑制可能な固形製剤を提供することを課題とする。   An object of the present invention is to provide a solid preparation capable of suppressing temporal discoloration caused by simultaneous blending of glucosamines, an organic acid and a sugar alcohol.

本発明者らは、上記課題を解決すべく鋭意検討した結果、グルコサミン類、有機酸及び糖アルコールの処方に有機酸カルシウムを付加し、ここで、糖アルコールを還元パラチノース、エリスリトール又はマルチトールとし、且つ有機酸カルシウムをクエン酸カルシウム又はグルコン酸カルシウムとした固形製剤とすることで、保存中の経時的変色が抑制されることがわかった。   As a result of intensive studies to solve the above problems, the present inventors add calcium of an organic acid to a formulation of glucosamines, an organic acid and a sugar alcohol, wherein the sugar alcohol is reduced palatinose, erythritol or maltitol. Moreover, it was found that, by setting the calcium salt of organic acid as calcium citrate or calcium gluconate as a solid preparation, discoloration over time during storage is suppressed.

かかる知見により得られた本発明の態様は次のとおりである。
(1)(a)グルコサミン類、(b)有機酸、(c)還元パラチノース、エリスリトール又はマルチトール及び(d)クエン酸カルシウム又はグルコン酸カルシウムを含有する固形製剤。
(2)有機酸がクエン酸である、(1)に記載の固形製剤。
(3)散剤の形態である、(1)又は(2)に記載の固形製剤。
The aspect of this invention obtained by this knowledge is as follows.
A solid preparation comprising (1) (a) glucosamines, (b) organic acid, (c) reduced palatinose, erythritol or maltitol and (d) calcium citrate or calcium gluconate.
(2) The solid preparation according to (1), wherein the organic acid is citric acid.
(3) The solid preparation according to (1) or (2), which is in the form of a powder.

本発明により、グルコサミン、糖アルコール及び有機酸を含有し、且つ保存中の経時的変色が抑制された固形製剤を提供することが可能となった。   According to the present invention, it has become possible to provide a solid preparation which contains glucosamine, a sugar alcohol and an organic acid and in which the discoloration over time during storage is suppressed.

「グルコサミン類」は、本発明において由来・製法等について特に制限はなく、天然物から精製して得られるもののみならず合成品をも利用することができ、市販のグルコサミン類もまた利用され得る。グルコサミン類としては、グルコサミン、その塩、又はそれらの誘導体のいずれも使用することもできる。グルコサミンの塩としては、硫酸塩、塩酸塩をはじめとする無機酸のほか、酢酸塩、クエン酸塩などの有機酸塩も使用することができるが、これらの中でも特に塩酸塩はクエン酸と糖アルコールとの同時配合により経時的変色を呈しやすい。また、グルコサミンの誘導体としては、D−グルコサミン、N−アセチルグルコサミン等の誘導体を使用することができる。これらのグルコサミン類は、1種類のみが用いられても良いし、2種類以上が組み合わせて用いられても良い。一般にグルコサミン類の有効量は、健康成人で一日あたり0.5〜1.5gとされている。本願発明の固形製剤において、グルコサミンは、10〜90重量%含有されることが好ましく、20〜80重量%がより好ましく、40〜80重量%が特に好ましい。   In the present invention, “glucosamines” are not particularly limited as to origin and production method, etc., and not only products obtained by purification from natural products but also synthetic products can be used, and commercially available glucosamines can also be used. . As glucosamines, either glucosamine, its salt, or derivatives thereof can also be used. As salts of glucosamine, inorganic acids such as sulfates and hydrochlorides, and organic acid salts such as acetates and citrates can also be used. Of these, especially hydrochlorides are citric acid and sugar It is easy to exhibit discoloration over time due to simultaneous blending with alcohol. Moreover, as a derivative of glucosamine, derivatives such as D-glucosamine, N-acetylglucosamine and the like can be used. Only one type of these glucosamines may be used, or two or more types may be used in combination. In general, the effective amount of glucosamines is 0.5 to 1.5 g per day for healthy adults. In the solid preparation of the present invention, glucosamine is preferably contained in an amount of 10 to 90% by weight, more preferably 20 to 80% by weight, and particularly preferably 40 to 80% by weight.

グルコサミン類含有固形製剤の製造にあたって、賦形剤として還元パラチノース、エリスリトール、マルチトール、ソルビトール、トレハロース等の糖アルコールを使用すると、いずれの糖アルコールを使用してもグルコサミン類及び有機酸との配合により保存中に黄褐色に変色してしまい,製品の品質を維持できない。本発明はクエン酸カルシウム又はグルコン酸カルシウムをさらに配合することにより上記課題を解決するものであるが、クエン酸カルシウムによる変色抑制効果は還元パラチノース又はエリスリトールを賦形剤として使用した固形製剤で強く認められ、マルチトールを賦形剤として使用した固形製剤では弱い変色抑制効果が認められた。そして意外にも、ソルビトール、トレハロース等の他の糖アルコールを賦形剤として使用した場合にはクエン酸カルシウムによる変色抑制効果が認められなかった。ここで本願発明の固形製剤において賦形剤として使用する糖アルコールとしては、還元パラチノース、エリスリトール又はマルチトールが好ましく、より好ましくは還元パラチノース又はエリスリトールであり、それぞれ固形製剤中に、5〜90重量%含有されることが好ましく、5〜75重量%がより好ましく、20〜40重量%が特に好ましい。 When sugar alcohols such as reduced palatinose, erythritol, maltitol, sorbitol and trehalose are used as excipients in the preparation of glucosamines-containing solid preparations, it is possible to mix them with glucosamines and organic acids regardless of which sugar alcohol is used. It turns yellowish brown during storage and the product quality can not be maintained. The present invention solves the above-mentioned problems by further blending calcium citrate or calcium gluconate, but the discoloration inhibitory effect by calcium citrate is strongly recognized in the solid preparation using reduced palatinose or erythritol as an excipient. In the solid preparation using maltitol as an excipient, a weak discoloration inhibitory effect was observed. And surprisingly, when other sugar alcohols such as sorbitol and trehalose were used as an excipient, no discoloration inhibitory effect by calcium citrate was observed. The sugar alcohol used as an excipient in the solid preparation of the present invention is preferably reduced palatinose, erythritol or maltitol, more preferably reduced palatinose or erythritol, each in an amount of 5 to 90% by weight in the solid preparation. It is preferable to contain, 5 to 75 weight% is more preferable, and 20 to 40 weight% is especially preferable.
