摘要:
[Object] By suppressing coloring of an adhesive preparation containing donepezil, a naturally colored appearance is realized.[Solution] In a method for suppressing coloring of an adhesive preparation having a support and a pressure-sensitive adhesive layer, which comprises a pressure-sensitive adhesive and donepezil in the pressure-sensitive adhesive layer, ascorbic acid, a metal salt or an ester thereof and metal metabisulfite salt are contained in the pressure-sensitive adhesive layer. This method preferably has: a step of preparing a mixture comprising the pressure-sensitive adhesive, the donepezil, the ascorbic acid, a metal salt or an ester thereof, and the metal metabisulfite salt; and a step of film-forming the pressure-sensitive adhesive layer by applying the mixture to the surface of the support.
