Abstract
An in situ film-forming methyl acetate-based solution of at least one absorbable, segmented block copolymer with amorphous and semi-crystalline segments contains at least one bioactive agent which exhibits antimicrobial, anti-inflammatory, antiviral, anesthetic, hemostatic, and/or antineoplastic activity. The absorbable polymers can be a polyaxial copolyester, polyether-ester and polyether-ester urethane. The solution can be applied (e.g., sprayed or swabbed) onto animal and human skin or accessible body cavities to prevent or treat one or more disorders preventable or treatable by the bioactive agent therein.
