ABSTRACT:
A dressing for debridement of necrotic and non-viable tissue in a wound, wherein the dressing comprises an effective amount of one or more proteolytic enzymes incorporated in a degradable polymeric material. The dressing of the invention provides effective debridement of necrotic wounds over a prolonged period of time, as the enzymes may be released over time. As the enzymes are incorporated in the polymeric material, a high stability is achieved.
