title: Controlled clinical trial of ranitidine in bleeding peptic ulcer.
abstract: One hundred and two patients were entered into a controlled, randomized clinical trial to assess the value of ranitidine versus placebo, given immediately after entry to hospital to modify the outcome of patients admitted to hospital with acute bleeding from peptic ulceration of the stomach or duodenum. The results indicated that ranitidine could not significantly modify the blood requirements, rebleeding rate or operation rate in this patient population during the initial hospital admission.
