A maintenance regimen of sucralfate 2 g at night for reduced relapse rate in duodenal ulcer disease

One hundred seventeen patients with recently healed duodenal ulcers were entered into a one-year maintenance study. Patients were randomly assigned to treatment with sucralfate 2 g at night, cimetidine 400 mg, or placebo. The sucralfate versus placebo leg of the study was double-blind, whereas the cimetidine leg was single-blind. Endoscopy was repeated on clinical relapse and routinely at six and 12 months. Ninety-six of the 117 patients were followed up for one year or to an endoscopically proven recurrence. The remaining 21 patients were excluded from analysis because of default or protocol violation. The one-year analysis showed by endoscopy that ulcers had recurred in 17 of the 31 sucralfate-treated patients, 19 of the 32 cimetidine-treated patients, and in 28 of the 33 placebo-treated patients. These data included asymptomatic recurrences in four, four, and three patients, respectively. The relapse rate at 24 weeks was greater in patients healed initially with a histamine (H 2 -blocker alone than in those healed initially with sucralfate alone, a combination of sucralfate with a H 2 -blocker or an antacid alone.
