PURPOSE:An application drug, obtained by laminating a pressuresensitive adhesive layer, consisting of polyvinylpyrrolidone, vinylpyrrolidone-vinyl acetate copolymer and a glycol, and containing a chemical on one side of a base material sheet, having rapid action, and effective for a long period. CONSTITUTION:An application drug obtained laminating a pressuresensitive adhesive layer, consisting of polyvinylpyrrolidone, vinylpyrrolidone-vinyl acetate copolymer and a glycol, and containing a chemical on one side of a base material sheet, e.g. polyethylene or polypropylene. The glycol is contained for imparting the tackiness to the polyvinylpyrrolidone and vinylpyrrolidone-vinyl acetate copolymer. A chemical conventionally used in application drugs may be used as the chemical. In the above-mentioned application drug, the chemical is percutaneously absorbed in about 30min, reaches the effective concentration in blood and is absorbed constantly for about 24hr. The application drug is further well compatible with the skin and can be suitably applied to the body.
