Randomized Controlled Trial
Prevention of recurrent idiopathic gastroduodenal ulcer bleeding: a double-blind, randomised trial.
Patients with a history of Helicobacter pylori-negative idiopathic bleeding ulcers have a considerable risk of recurrent ulcer complications. We hypothesised that a proton pump inhibitor (lansoprazole) is superior to a histamine 2 receptor antagonist (famotidine) for the prevention of recurrent ulcer bleeding in such patients. ⋯ This 2-year, double-blind randomised trial showed that among patients with a history of H. pylori-negative idiopathic ulcer bleeding, recurrent bleeding rates were comparable between users of lansoprazole and famotidine, although a small difference in efficacy cannot be excluded.
