BANDAGE FOR SUSTAINED DELIVERY OF DRUGS

摘要

A bandage (10) for the transdermal or topical administration of a drug (14) over an extended period of time comprising an impermeable backing sheet (12), a solid drug pellet (14) on the backing sheet (12), and a layer of contact adhesive (18) covering the pellet (14) and backing sheet (12). In another form, the adhesive (18) is carried by a web (20) made of a non-woven fabric. Control over the rate of dissolution of the solid drug (14) can be achieved by varying the type of web fabric (20), the type of adhesive (18), and the thickness of the adhesive (18).
