DEVELOPMENT AND EVALUATION OF MEDICATED BIODEGRADABLE FILM FOR WOUNDS AND BURNS
AbstractAs a part of our ongoing effect to develop a biodegradable medicated film for wound healing using chitosan and HPMC as polymers. The drug used is Silver sulfadiazine. This formulation produces better biodegradability and bioadhesion. The biodegradable film is non-toxic and non-irritant to the skin. An animal wound model was performed on the back of the rats and treated, respectively with medicated biodegradable film and with a marketed product. There are no infections found during the period of study. The wound healed within 6 days, in the case of medicated film formulation, but not with the marketed cream. Medicated films could be a good alternative to conventional wound dressings, which is painful and injurious. The film adheres to open wounds, and therefore it is good protection providing a moist healing environment. Better patient compliance is an added advantage as it does not require repeated application.
