More Information
Summary:Provided is a felbinac-containing external patch which can exhibit high drug release properties, low skin irritation, and high drug stability, wherein felbinac having an average particle diameter of 5 µm or more and less than 100 µm is dispersed and mixed in an adhesive base including a styrene-isoprene-styrene block copolymer, an alicyclic saturated hydrocarbon resin, a softener, and diethyl sebacate, and does not contain L-menthol. Specifically, in the felbinac-containing external patch, 0.1 to 10% by weight of felbinac having an average particle diameter of 5 µm or more and less than 100 µm is dispersed and mixed in an adhesive base including 10 to 30% by weight of a styrene-isoprene-styrene block copolymer, 10 to 50% by weight of an alicyclic saturated hydrocarbon resin, 10 to 75% by weight of a softener, and 0.1 to 10% by weight of diethyl sebacate.
