Abstract
Dermal patches containing a flexible, crosslinked, polymeric gel comprising polyvinyl alcohol and a crosslinking agent comprising a multivalent element, e.g., titanium complexed with hydroxyalkyl amines, are disclosed. The dermal patches can be used to deliver pharmaceutically active agents to the dermal surface of a mammal, or alternatively can be used without the pharmaceutically active agents. The dermal patches have properties, such as, for example, a high degree of water absorbency, oxygen permeability and physiological compatibility which render them suitable for treatment of open skin, e.g., lacerations, burns or blisters, as well as unbroken, intact skin.
