Abstract
After an active duodenal ulcer has healed in response to medical therapy, the rate of recurrence during the subsequent year is relatively high. We therefore enrolled 140 patients with healed duodenal ulcers in a two-year randomized, double-blind trial comparing maintenance therapy (ranitidine, 150 mg nightly) with placebo for the prevention of recurrent duodenal ulceration. We performed endoscopy annually and when symptoms suggested the recurrence of ulcers. Verified recurrent ulcers in either group were treated for four or eight weeks with open-label ranitidine (150 mg twice a day). Patients whose ulcers healed within eight weeks resumed randomized treatment.
