  • Title: Postprandial gastric, pancreatic, and biliary response to histamine H2-receptor antagonists active duodenal ulcer.
    Author: Longstreth GF, Go VL, Malagelada JR.
    Journal: Gastroenterology; 1977 Jan; 72(1):9-13. PubMed ID: 11148.
    Abstract:
    Histamine H2-receptor antagonists are potentially useful agents in duodenal ulcer and knowledge of their effect on postprandial digestive events will contribute to their clinical application. We studied the effect of 200- and 300-mg doses of cimetidine, an H2-receptor antagonist, taken with an ordinary meal, on gastric, pancreatic, and biliary function. Both doses significantly reduced acid output and its delivery into the duodenum. Gastric secretory volume and pepsin output were less affected. Acid inhibition was related to blood drug levels and was less than that previously found at night in nocturnal fasting studies. As the stomach emptied the food, the gastric pH rose. The fractional gastric emptying rate, pancreatic enzyme, and bile acid outputs were unaltered. Cimetidine taken orally with meals at these doses is a potent gastric antisecretory agent without affecting other postprandial gastric, pancreatic, or biliary functions.
