Abstract

PURPOSE:To obtain a plaster capable of administering a drug to a diseased part or circulation system of body over a long period and effective in prolonging the action of the drug, by applying a drug-containing tacky adhesive polymer layer having a specific double-layered structure on a drug-impermeable substrate. CONSTITUTION:A drug-impermeable substrate 1 is coated with a drug-containing tacky adhesive polymer layer 2 having double-layered structure consisting of an inner polymer layer 2A compounded with a drug and, as necessary, a release- assistant and essentially free from tackiness and an outer polymer layer 2B compounded with a drug and, as necessary, a release assistant and having tacky adhesivity. The crosslinking density of a prescribed part (e.g. the part between the surface and the dashed line 4) on the exposed surface 3 of the polymer layer 2B is made higher than that of the polymer 2A. The part having higher crosslinking density preferably has a thickness corresponding to about 1/50-1/2 of the total thickness of the tacky adhesive polymer layer or about 3-20mu from the surface 3.
