title: Inhibition of gastrin secretion by sulpiride treatment in duodenal ulcer patients.
abstract: The serum gastrin response to whole beef extract was measured in 14 duodenal ulcer patients before and after sulpiride administration. A significant inhibition of response was found both after acute intramuscular injection of the drug and after oral administration for 1 week. Fasting serum gastrin was also significantly reduced after chronic treatment; gastric acid secretion did not change. Although the mechanism of the gastrin-lowering action of sulpiride is unknown, it could be mediated by some known effects(s) of the drug, such as modifications in brain monoamine metabolism or perhaps reduced growth hormone secretion.
