Direct comparison between the ulcer-healing effects of two H(+)-K(+)-ATPase inhibitors, one M1-selective antimuscarinic and one H2 receptor antagonist in the rat.

Abstract

A direct comparison of the ulcer-healing effects of two H(+)-K(+)-ATPase inhibitors (pantoprazole and omeprazole), one M1 antimuscarinic (telenzepine) and one H2 receptor antagonist (cimetidine) was performed in the rat. Gastric and duodenal ulcers were induced by local application of acetic acid and thereafter treated over 10 days by the test drugs. Overall and on a molar basis, ulcer healing was comparably accelerated by pantoprazole, omeprazole and telenzepine and less so by cimetidine. The same rank order was found with respect to the inhibition of gastric acid secretion in the modified Shay rat.
