Abstract

Background & objectives: The aetiology of gastric ulcers is not completely understood and continuous use of anti-ulcer agents leads to many side effects. In this study we evaluated the anti-ulcer effcacy of a polyherbal formulation with potent antioxidant activity in aspirin and pyloric ligature induced gastric ulcers in rats. Methods: The effcacy of the polyherbal formulation NR-ANX-C (composed of the extracts from Withania somnifera, Camellia sinensis, Ocimum sanctum, shilajith and triphala) was evaluated in terms of antioxidant potential as assessed in terms of protection from lipid peroxidation and the antiulcer activity as seen by the area of gastric lesions, gastric juice volume, gastric pH, total acidity and total adherent gastric mucus content. Results: In our study, NR-ANX-C (25 and 50 mg/kg) was more effcacious than ranitidine in reducing ulcer index in both the models. At the highest dose tested (50 mg/kg), NR-ANX-C was comparable to omeprazole in preventing ulcer formation in the pyloric ligature model. NR-ANX-C showed a dose-dependent decrease in gastric juice volume and total acidity in both the models. A dose-dependent increase in gastric pH and total adherent gastric mucus was also seen in NR-ANX-C treated groups. The extent of lipid peroxidation was also reduced in the test drug treated groups. Interpretation & conclusion: Based on our fndings, we presume that the cytoprotective, anti-secretary and antioxidant properties of NR-ANX-C were responsible for its anti-ulcer activity. These fndings suggest the potential for use of NR-ANX-C as an adjuvant in the treatment of gastric ulcer.
