Action of omeprazole (a benzimidazole derivative) on secretory responses to sham feeding and pentagastrin and upon serum gastrin and pancreatic polypeptide in duodenal ulcer patients.
The effects of omeprazole, a benzimidazole derivative, have been determined on the secretory responses to modified sham feeding and pentagastrin, and upon serum gastrin and pancreatic polypeptide concentrations in duodenal ulcer patients. Intragastric administration of omeprazole in doses of 2 and 6 mumol/kg produced, respectively, about 50% and 90% reduction in acid outputs in responses to modified sham feeding and pentagastrin without affecting serum gastrin and pancreatic polypeptide response to modified sham feeding.
