Background & Objective: Since calcium has got importance in physiology and the objective of the present study is to study the effect of different calcium channel blockers through i.c.v administration on gastric and duodenal ulcers. Methods: The effect of different calcium channel blockers on gastric and duodenal ulcers were evaluated by using different experimental models such as acetic acid induced chronic gastric ulcer, pylorus ligation induced gastric ulcers, ethanol induced gastric ulcers, stress induced gastric ulcers, and cysteamine induced duodenal ulcers. In all these models the...
