[Effect of an H+, K+-ATPase inhibitor, omeprazole (OPZ), on gastric acid secretion and gastric or duodenal lesion. Comparison with an H2-receptor antagonist, famotidine (FMD)].


In pylorus ligated rats, OPZ inhibited gastric acid secretion dose-dependently, with a potency greater than that of FMD. At the same time, OPZ increased gastric K+ secretion and inhibited pepsin and Na+ secretions at the highest dose. In Heidenhain pouch dogs, single injection of OPZ inhibited gastric acid secretion induced by histamine to a degree almost… (More)
