ABSTRACT:
A controlled-release bandage containing therapeutic agents in a poly(vinyl alcohol) cryogel is disclosed. The bandage may include particulate absorbants such as ion exchange resins and hydrophobic particles to further insure controlled and constant release of therapeutic agents. The bandage may also include plasticizing agents to provide softness in the event of drying the bandage.
