ADHESIVE PREPARATION FOR PERCUTANEOUS ABSORPTION

摘要

An adhesive preparation for percutaneous absorption in which high drug permeability at a low drug concentration and satisfactory drug stability have been obtained by regulating the solubility of a drug in a base. The adhesive preparation comprises a base comprising a styrene-isoprene-styrene block copolymer and norethisterone contained in the base. Preferably, the drug is dissolved in the base in an amount of up to 2 wt.% based on the whole base.
