AbstractPeptic ulcer diseases are one of the wide spread diseases. The causes of peptic ulcer diseases are increases gastric acid secretion. Studies focusing on the harmful effect of intra-gastric administration of ethanol which results in gastric mucosal injury, characterized by mucosal edema, sub-epithelial hemorrhage and inflammatory cell infiltration. Omeprazole and pantoprazole are proton pump inhibitors used in the treatment of gastric ulcer and gastroesophageal disease that inhibit gastric acid secretion by blocking the H+/K+- adenosine triphosphate enzyme. The present study was carried out to determine the anti-ulcer activity of proton pump inhibitors ( omeprazole 10mg/kg and pantoprazole 3 mg/kg) on ethanol- induced ulcer rat model. Healthy Sprague Dawley rats with 12-14 weeks of age of either sex weighing between 150-200 gm. were used for present study. The animals were divided into three groups six animals in each .The ulcer was induced by administering ethanol 50% orally and the treated groups was drenched 10mg/kg omeprazole and pantoprazole 3mg/kg. The anti-ulcer activity of omeprazole and pantoprazole was able to protect against ulcer formation by ethanol was indicated by a decrease in ulcer index of both treated groups. From this study it can be concluded that omeprazole and pantoprazole possess anti-ulcerogenic activity. Besides , omeprazole might be better than pantoprazole in protection against ethanol- induced ulcer.
