This study has examined the inhibition produced by metiamide on the gastric secretion of acid and pepsin in 13 patients with duodenal and three with gastric ulcer. The effect of metiamide on the response to a range of doses of pentagastrin in three normal individuals was determined, as was the interaction of metiamide and atropine on prolonged basal secretion. Metiamide inhibited the secretion of acid more than pepsin and the gastric secretion of patients with gastric ulcer more than duodenal ulcer. Metiamide inhibited both the maximal secretory response attainable with pentagastrin and decreased the sensitivity to pentagastrin. Atropine augmented and prolonged the action of metiamide.

Metiamide greatly reduced pentagastrin-stimulated and overnight secretion of acid and pepsin in 11 patients with duodenal ulcer and virtually abolished gastric secretion in three patients with gastric ulcer. The drug was equally effective when infused intravenously or intraduodenally. A therapeutic trial of Metiamide is warranted in diseases caused or aggravated by excess gastric secretion of acid and pepsin.

The effect of metiamide on reserpine-induced gastric ulcers and on gastric secretion during 6 h after ip administration was investigated in conscious intact rats and in rats with chronic gastric fistula. Reserpine, 3 mg/kg ip increased substantially the concentration of gastric acid in the first 4 h. Metiamide given every 3 h in a low dose (0.01 mumol/kg) intensified reserpine-induced gastric ulcers and also significantly increased the reserpine-induced acid concentration and output. In larger doses, (50-100 mumol/kg) metiamide considerably diminished gastric ulcer development and decreased gastric acid concentration. Given every 2 h metiamide in doses of 50-100 mumol/kg almost completely abolished gastric ulcer formation and markedly reduced the secretion of gastric acid in reserpinized rats. Anti-ulcer effect of metiamide was stronger than its antisecretory action, suggesting also the antiulcer action of metiamide other than inhibition of acid secretion. The results suggest that in conscious rats histamine H2-receptors are involved in reserpine-induced gastric ulcer development and gastric acid secretion. The antiulcer effect of metiamide may in part depend on its antisecretory action.
