Abstract

PURPOSE: The titled pharmaceutical, prepared by laminating a chemical stroage layer on a backing member, and further laminating a porous chemical-permeable resin layer containing pores filled with a solvent incapable of dissolving the chemical on the above-mentioned chemical storage layer in order, and capable of releasing the chemical at a controlled rate for a long term.
CONSTITUTION: A pharmaceutical for prolonged release of a chemical consisting of a backing member 1 preferably consisting of a flexible chemical-impermeable sheet material, a chemical storage layer 2, laminated on the above-mentioned backing member 1, and consisting of the chemical contained in a chemical- permeable resin, e.g. a silicone resin or polymethacrylic acid ester, and a diffusion controlling layer 3, laminated on the above-mentioned chemical storage layer 2, and consisting of a porous chemical-permeable resin 4 containing pores 5 filled with a solvent, e.g. mineral oil or glycol, incapable of dissolving the chemical. The permeation of the chemical is prevented by the solvent dispersed in the chemical-permeable resin layer, and complicated continuous chemical passages are formed in the diffusion controlling layer 3.
