Nocturnal therapy with famotidine for 1 year is effective in preventing relapse of gastric ulcer.

A multicentre, double-blind, randomized, placebo-controlled trial was undertaken to investigate the therapeutic efficacy of a nocturnal dose of famotidine 20 mg to reduce the 1 year relapse rate of recently healed gastric ulcers. Twenty investigators in eight countries randomized 202 patients with endoscopically confirmed healed gastric ulcers. Repeat endoscopies were performed at 6 and 12 months or for symptoms compatible with ulcer relapse. A per protocol analysis of cumulative life table relapse at 12 months showed that famotidine 20 mg was superior to placebo in reducing gastric ulcer relapse, 24 versus 50%, respectively (P less than 0.01). Both placebo and famotidine were well tolerated. Since nocturnal dosing with famotidine 20 mg is effective in preventing gastric ulcer relapse over a 1-year period and is well tolerated, it offers a therapeutic option for the long-term treatment of patients with gastric ulcer.
