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

摘要

The purpose of the present invention is to provide a slow releasable non aqueous skin patch composition of favorable adhesive strength. The addition of a powder component (a filler or the like) allows this skin patch to achieve improved adhesive strength of the skin patch and improved release of the drug. As a result the adhesive strength of the skin patch is maintained for a long time thereby making it possible to improve percutaneous absorption and enable slow release. The use of the skin patch composition containing this powder component causes a drug regardless of the type of drug to be dissolved into an organic solvent or ionic liquid and to be incorporated into the non aqueous skin patch as a principal drug solution along with the organic solvent thereby realizing a preparation of both improved percutaneous absorption and improved slow release.
