Prostaglandin (PG) has been reported to be an important protective and acid suppressive factor in the gastric mucosa. The objective of the study was to develop and evaluate a stomach specific drug delivery system for controlled release of Misoprostal a PE analogue for gastric ulcer induced NSAIDs. Floating microspheres were prepared by emulsification-solvent evaporation method using ethyl cellulose as a polymer, carbo pol as mucoadhesive polymer. Ulcers were induced by the oral administration of absolute ethanol (5 mL/kg) to 24 h fasted Wistar male rats (n=8), weighing 200 g. Sodium bicarbonate solution, misoprostal solution and drug loaded microspheres were tested. Formulations were administered orally 1h before the administration of ethanol. Prior to the oral administration, rats were anesthetized with ethylic ether. After 2 h of ethanol administration, animals were sacrificed
