Percutaneous absorption-type pharmaceutical preparation using a metal chloride, preferably sodium chloride, for preventing cohesive failure

摘要

A stable percutaneous absorption-type pharmaceutical preparation for percutaneous administration of drugs except for selegiline and selegiline hydrochloride, which does not suffer a decrease in the cohesive force of the adhesive layer therein even in the presence of sweat components due to perspiration during wear and which is free from cohesive failure and resultant adhesive remaining when stripped off. A percutaneous absorption-type pharmaceutical preparation which comprises: a support; and an adhesive layer containing an adhesive, a metal chloride and a percutaneously-absorptive drug except for selegiline and selegiline hydrochloride, wherein the adhesive layer is subjected to a crosslinking treatment.
