Effect of histamine-H2-receptor antagonists on the exocrine pancreatic secretion

Abstract

Pancreatic exocrine secretion has been studied in 10 patients with documented duodenal ulcer before and after 4 weeks of cimetidine treatment (1 g/die). This chronic 'short term' cimetidine administration did not result in any substantial modification of exo-pancreatic response stimulated by Secretin and Caerulein. From this point of view the drug could be employed in the treatment of pancreatic insufficiency in order to obtain a better utilization of pancreatic enzyme supplement. It is, however, questionable if such a 'long-term' therapy may be responsible for the appearance or the relapse of a peptic ulcer.
