Description

【発明の詳細な説明】 [産業上の利用分野] 本発明は、非イオン性界面活性剤を添加することにより
カルボキシビニルポリマーの分散状態を良好にした坐剤
に関するものである。
DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a suppository in which a dispersion state of a carboxyvinyl polymer is improved by adding a nonionic surfactant.

[従来の技術] カルボキシビニルポリマーを坐剤に配合することは特開
昭59−163310により知られている。これによれば炭素数

[Prior Art] The incorporation of carboxyvinyl polymers into suppositories is known from JP-A-59-163310. According to this, the rectal absorption of the drug can be improved by using the fatty acid having 8 to 10 carbon atoms and a salt thereof in combination.

[発明が解決しようとする問題点] 痔の治療に用いる坐剤は挿入部に留まっていることが望

[Problems to be Solved by the Invention] Although it is desirable that the suppository used for the treatment of hemorrhoids remains in the insertion part, a typical suppository is, for example, 10 to 20 at body temperature in the case of oily suppositories. It often dissolves and diffuses in about a minute, and the medicinal component in the suppository often moves from the insertion site, that is, the hemorrhoid affected site.

ので、作業上の面からも問題であった。
It was expected that the incorporation of carboxyvinyl polymers into suppositories would absorb water in the rectum, swell the suppositories themselves, and remain at the insertion site for extended periods of time. However, when a carboxyvinyl polymer is mixed in a base containing fatty acid glyceride as a main component, the carboxyvinyl polymer has strong hydrophilicity and the fatty acid glyceride is hydrophobic, which makes the carboxyvinyl polymer particularly prone to aggregation. ing. In the production of suppositories, if the carboxyvinyl polymer aggregates between the piston and the cylinder during filling, the filling amount may vary, or the piston may stop and it may not be possible to fill the suppository.

In addition, if the carboxyvinyl polymer aggregates and its particle size exceeds 1 mm, not only does the appearance of the molded suppository deteriorate, but naturally it also affects the dispersibility of other compounding ingredients, and There is unevenness in the concentration of the compounding ingredients in one agent, and the release and absorption of the drug also vary.

[Means for Solving Problems] The inventors of the present invention have made extensive studies in view of the above problems, and as a result,
In addition to improving the dispersibility of the compounding ingredients in the suppository by adding a carboxyvinyl polymer and a nonionic surfactant in the base containing fatty acid glyceride as a main component,
The present invention has been completed based on this finding, since it was found that there is less variation in filling during the production of suppositories.

In the present invention, the content of carboxyvinyl polymer is preferably 1 to 15% by weight. This is because if the content of carboxyvinyl polymer is less than 1% by weight, the suppository does not remain at the insertion site, and if it is more than 15% by weight, it becomes difficult to manufacture the suppository.

In order to mix the carboxyvinyl polymer in the suppository in a good dispersed state, it is preferable to make the base containing fatty acid glyceride as the main component hydrophilic enough to prevent the carboxyvinyl polymer from swelling. For that purpose, the fatty acid glyceride preferably has a hydroxyl value of 20 to 70, particularly preferably 40 to 60. The amount is preferably 50 to 95% by weight, more preferably 70 to 80% by weight. If it exceeds this range, the carboxyvinyl polymer tends to aggregate in any case.

Further, the HLB value of the nonionic surfactant is preferably 9-18, more preferably 12-15. The amount of the nonionic surfactant added is preferably 0.1 to 10% by weight, more preferably 3 to 8% by weight.

If the non-ionic surfactant having an HLB value of more than 9 exceeds 10% by weight, the hydrophilicity of the base becomes too strong.
The carboxyvinyl polymer swells, the viscosity becomes high, and filling becomes difficult. On the other hand, if the content is lower than 0.1% by weight, the carboxyvinyl polymer is likely to aggregate.
