PERCUTANEOUSLY ABSORBABLE PREPARATION, PERCUTANEOUSLY ABSORBABLE PREPARATION-HOLDING SHEET, AND PERCUTANEOUSLY ABSORBABLE PREPARATION-HOLDING EQUIPMENT

摘要

PPROBLEM TO BE SOLVED: To provide self-dissolving needle-like or filamentous shape percutaneously absorbable preparations by which poorly absorbable drugs into the body through the skin or the like is efficiently administered. PSOLUTION: The needle-like or filamentous shape percutaneously absorbable preparation is produced by using a base comprising at least one material selected from the group consisting of proteins, polysaccharides, polyvinyl alcohols, carboxyvinyl polymers and sodium polyacrylates. A target substance is gradually released by forming a water-insoluble layer on its surface, holding the target substance in porous materials or using the target substance having a long-time sustention. The invention also provides a percutaneously absorbable preparation-holding sheet for holding the preparation on at least one side of a support, and preparation-holding equipment for holding the preparation so as to enable efficient administration thereof.
