Abstract
A multilayered composite sheet for delivering one or more therapeutic agents to the skin is disclosed. The composite sheet comprises a flexible porous polymer with open cells of a sufficient size for holding a therapeutic agent, an encapsulating agent for encapsulating the flexible porous polymer and therapeutic agent, and an enrobing agent for enrobing the encapsulated flexible porous polymer and therapeutic agent. Additional layers of the flexible porous polymer, therapeutic agent and other materials are added to the first layer which is in contact with the skin. The first layer has particular particle sizes for the flexible porous polymer, open cell size, and therapeutic agent allowing for relatively quick delivery of the therapeutic agent to the skin. Each successive layer placed on top of the first layer has incrementally larger particle sizes of the flexible porous polymer and therapeutic agent providing successively longer delivery times than the first layer.
