Cimetidine: a review of its pharmacological properties and therapeutic efficacy in peptic ulcer disease.

Abstract
Cimetidine is a specific competitive histamine H2-receptor antagonist which effectively inhibits gastric acid secretion and is advocated for the treatment of chronic peptic ulceration, haemorrhage from erosive gastritis, and the control of gastric hypersecretion and peptic ulceration in the Zollinger-Ellison syndrome. Placebo-controlled trials in outpatients have demonstrated its efficacy in promoting the healing of endoscopically diagnosed duodenal ulceration, during a period of 4 to 6 weeks, but its role in the treatment of gastric ulcer is less clear. Preliminary evidence suggests that maintenance therapy with cimetidine reduces the rate of recurrence of duodenal ulcer, but further studies are required to clarify its role in this situation and in the treatment of oesophagitis and acute gastrointestinal haemorrhage. Cimetidine controls the peptic ulceration of Zollinger-Ellison syndrome in most patients when given continuously for up to 2 years. Side-effects have generally been trivial and have very seldom necessitated withdrawal of therapy except in the rare occurrence of gynaecomastia. The haematological abnormalities particularly agranulocytosis, which lead to the withdrawal from clinical use of metiamide, have not been reported with cimetidine, except for 1 case of transient neutropenia. The safety of long-term cimetidine administration has yet to be determined.
