    Abstract:
    In an attempt for better treatment of partial thickness burn wounds topical ointments containing metronidazole and norfloxacin in different bases were prepared and in vitro release was conducted in phosphate buffer pH 6. It was found that, diffusion of the metronidazole and norfloxacin from the lanolin petrolatum base with 0.25% w/w dimethyl sulfoxide was maximum through hairless rat abdominal skin. Antimicrobial activity of different prepared formulations was found to be more effective both against aerobic and anaerobic bacteria than marketed formulation (1% silver sulfadiazine cream USP). Formulations were significantly effective as compared to that of marketed formulation in wound contraction of the partial thickness burn wound. Histopathological reports supported effectiveness of formulations. It was found that 1% metronidazole and 1% norfloxacin ointments are suitable for treating the partial thickness burn wound.
