Abstract
Described and claimed are biologically useful crosslinked copolymers of vinyl pyrrolidone and allylamine suitable for various preventative and therapeutic applications to intact or injured skin. Coatings of these copolymers, either preformed or prepared in situ on the skin may deliver medicaments to the skin, may serve as an iontophoretic medium, may provide electrical contact with the body, may regulate or control moisture loss from injured integument. Monolithic devices for the delivery of pharmaceutically active agents within living tissue may be formulated from these copolymers.
