An in situ film-forming sprayable methyl acetate-based solution of at least one absorbable, low-crystallinity, segmented copolymer 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 and the bioactive solution thereof can be applied onto animal and human skin or accessible body cavities to prevent or treat one or more disorder susceptible to the bioactive agent therein.
