title: Omeprazole-like compounds on histamine-stimulated acid and peptic secretions in conscious dog and cat.
abstract: A newly synthetized aniline derivative series has been tested on histamine-stimulated gastric acid secretion in conscious cats and dogs and compared to the proton pump inhibitors omeprazole and NC 1300. The compounds markedly and long-lastingly inhibited acid output with a potency lower than omeprazole but very close to the reference compound NC 1300. The results show that the introduction of a nitrogen atom, irrespective of the position in the benzimidazole ring does not seem to influence the gastric antisecretory activity.
