[Therapy of duodenal ulcer using cimetidine].

55 patients with endoscopically confirmed duodenal ulcers received either cimetidine (26 patients) or placebo (29 patients) in a double-blind trial. At four weeks, 85% of the patients treated with cimetidine and 62% of those receiving placebo had endoscopically healed ulcers. This difference is not statistically significant. However, patients on cimetidine showed a more rapid and statistically significant reduction in the size of their ulcers.
