Protection against gastric ulcer by verapamil.

Summary The effect of verapamil, a calcium channel blocker, was studied against stress (cold restraint), aspirin and pylorus ligation induced gastric ulcers in rats. Verapamil inhibited ulcerogenic response and ulcer index in all the three types of ulcers. Verapamil also decreased total and free gastric acidity without changing gastric secretory volume.
