Objective: The objective of the study is to evaluate the protective effect of a herbal formulation on the mutagenic effect of Omeprazole in mice. Materials and methods: Four groups of adult Swiss mice (6-8 weeks old) weighing 18-22 gm (n = 6) were used. The normal control group received saline and test group –I animals were treated with Omeprazole (25 mg/mouse, p.o..) to sub group-1 and (50 mg/mouse. p.o.) to sub group-II for five days. To test group - II Omeprazole is administered along vitamin E (50 mg/kg, p.o.) for a period of 35 days. Test group-III has received herbal formulation (1.3 mg/mouse, p.o.) for 35 days. On 35th day the animals were sacrificed by cervical dislocation and sperm head abnormality assay was performed. Results: Omeprazole which was administered in lethal dose has showed a dose dependent mean increase in sperm abnormalities. Omeprazole with vitamin E showed that there is significant decrease in the percentage of abnormal sperm in lower doses of Omeprazole i.e. 25 mg than with 50 mg dose. A similar protection was observed in the group treated with herbal formulation challenged by Omeprazole. Conclusion: Omeprazole is capable of inducing abnormalities in mice in a dose dependent manner perhaps of its unscheduled DNA synthesis. Vitamin E offered protection on the sperm abnormalities of mice due to its anti-oxidant activity. Herbal formulation has also showed a better protection on the mutagenic effect of Omeprazole in mice as compared to that of vitamin E.
