Abstract:
The present invention provides a composition for a non-aqueous patch preparation having an excellent adhesibility which can sustainedly release a drug. The patch preparation of the present invention can improve the adhesibility thereof as well as the release property of a drug by the addition of powder ingredient (e.g. a filler). As a result, the long-time sustention of the adhesibility of patch preparations can achieve the 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 patch preparation of the present invention, and thereby a preparation with the improved transdermal-absorbability and sustained release can prepared.

Claim (Index 1):
A composition for a non-aqueous patch preparation comprising a drug, an organic solvent, and a powder, wherein\n the powder is at least one selected from the group consisting of crystalline cellulose, starch, carmellose, carmellose metal salt, kaolin, agar, carrageenan, pectin, and powdered sugar, and the powder for an adhesive layer is contained as shown in the following formula:\n 0.2\u00d7(the weight of the adhesive layer)\u00d7(the bulk density of the powder)\u2264the amount of the powder to be added\u22640.6\u00d7(the weight of the adhesive layer)\u00d7(the tap density of the powder).
