Hydrogel wound dressing containing liposome-encapsulated therapeutic agent

摘要

The present invention is directed to a hydrogel wound dressing which effectively releases a therapeutic agent over a prolonged period of time. Liposomal therapeutic agents, such as antibiotics and antiseptics, are incorporated into hydrogels and the hydrogel/liposomal matrix is formed into a sheet. This hydrogel/liposomal sheet is placed on top of an outer layer (optionally coated with a medical-grade adhesive) and then applied to a wound. The present invention is particularly useful for treating and preventing infections in wounds.
