ABSTRACT:
Sustained-release percutaneous preparations which have at least two adhesive layers and in which a drug is contained in the layer farthest from the skin and a solid powder is dispersed in an adhesive layer other than the layer farthest from the skin provide slow release of the drug. By varying the kind and concentration of the solid powder, the rate of release of the drug from the preparations can be controlled.
