Self-dissolving needle-like or filamentous shape percutaneously absorbable preparations, by which inherently poorly absorbable drugs into the body through the skin is efficiently administered. The preparations are made of at least one material selected from the group consisting of proteins, polysaccharides, polyvinyl alcohols, carboxyvinyl polymers and sodium polyacrylic acids. An active substance contained therein is released in a sustained-release fashion (1) by forming a water-insoluble layer on its surface, (2) by holding the active substance in porous materials, or (3) by imparting a long-acting characteristic to the active substance. The present invention also provides a sheet-like carrier for holding the preparations on at least one of the sides thereof, and a piece of equipment for holding the preparations so as to facilitate the administration of them.
A percutaneously absorbable preparation adapted for insertion into skin to percutaneously administer an objective substance into the body, comprising a base consisting of a water-soluble polymer substance and the objective substance held in the base,
