title: Effect of omeprazole on delayed healing of acetic acid-induced gastric ulcers in rats.
abstract: Omeprazole, a gastric mucosal proton pump inhibitor, significantly and dose-dependently prevented the delayed healing of acetic acid-induced gastric ulcers in response to repeatedly administered indomethacin to rats. Both basal and histamine-stimulated gastric acid secretions in rats with acetic acid-induced ulcers that were given indomethacin were markedly and persistently (greater than 24 hr) inhibited after 4 weeks treatment with omeprazole. The prevention of delayed ulcer healing by omeprazole appears to be due to its long-lasting antisecretory activity.
