LOXOPROFEN SODIUM-CONTAINING ADHESIVE PATCH FOR EXTERNAL APPLICATIONS

摘要

Provided is a loxoprofen sodium-containing adhesive patch for external applications, which has high transdermal absorbability of the main ingredient contained therein and has high stability so that the production of any decomposition product can be prevented during storage. An adhesive patch for external applications, comprising a support and an adhesive agent layer arranged on the support and containing 0.1 to 10 wt% of loxoprofen sodium, wherein the adhesive agent layer comprises 5 to 30 wt% of a styrene-isoprene-styrene block copolymer, 10 to 50 wt% of an alicyclic saturated hydrocarbon resin, 0.1 to 1 wt% of lactic acid and 5 to 15 wt% of a higher fatty acid and the ratio of the content of lactic acid to the content of the higher fatty acid (i.e., (lactic acid)/(higher fatty acid)) is 1/50 to 1/5.
