ADHESIVE PREPARATION COMPOSITION OBTAINED BY BLENDING DRUG, ORGANIC SOLVENT, LIPOPHILIC OINTMENT BASE, AND POWDER

摘要

The object of the present invention is to provide a composition for a non-aqueous patch preparation with excellent adhesibility which can sustainedly release a drug. The patch preparation of the present invention can improve the adhesibility of the patch preparation and the release property of a drug by the addition of a powder ingredient (a filler or the like). As a result, the long-time sustention of the adhesibility of tape preparations enables an improvement of the transdermal absorbability and the sustained release of a drug. By the use of a composition for a patch preparation comprising this powder ingredient, a drug, regardless of the type of a drug is dissolved in an organic solvent or an ionic liquid to prepare a drug solution comprising the organic solvent, the drug solution is incorporated into the non-aqueous parch preparation of the present invention, and thereby a preparation with the improved transdermal absorbability and the improved sustained release can prepared.
