Abstract

Disclosed is a dissolvable, gel-forming film, and methods for its use, comprising a water-soluble cellulose ether, a hydrophilic rheological modifying agent, and an active proteolytic enzyme or other drug substance. The gel-forming film has a water content of less than 15% w/w and is capable of forming a hydrogel when contacted with water or other aqueous medium. The disclosed films achieve delivery of stable proteolytic enzymes to the desired site of action in a manner that provides uniform delivery of the enzymes.
