Abstract
A composite dressing including a first polymeric layer, a second polymeric layer, a metal oxide, and a pharmaceutical active material is provided. The second polymeric layer is biocompatible and is disposed on a surface of the first polymeric layer. The metal oxide is distributed inside or on at least one surface of the first polymeric layer, while the pharmaceutical active material is distributed inside or on at least one surface of the second polymeric layer.
