Abstract

A 24-week, double-blind, randomized study at 13 centres compared the efficacy and safety of 20 mg famotidine nocte and 150 mg ranitidine h.s. for the prevention of duodenal ulcer recurrence. All participants had been successfully treated for an acute duodenal ulcer with 40 mg famotidine nocte. Patients were endoscoped at baseline and at 24 weeks, unless symptoms warranted earlier examination: of the 208 patients enrolled, 86 who received famotidine and 84 who received ranitidine met all protocol criteria and were considered evaluable. Intention to treat and per protocol analyses showed non-significant trends in favour of famotidine (P = 0.44 and 0.16, respectively). During the 24-week observation period, 16.3% of the famotidine group and 25% of the ranitidine group had an ulcer recurrence (95% CI of percentage difference -0.22 + 0.04). At 24 weeks, relief of day and night pain was reported by 81.2% and 91.8% of the famotidine-treated patients, respectively. The corresponding figures in the ranitidine group were 73.5% and 85.5%. No laboratory abnormalities related to the study-drugs were noted and only two drug related (possibly or probably) adverse experiences were reported, both in the famotidine group. The data from this study therefore, supports the conclusion that the efficacy of 20 mg famotidine nocte is comparable to that of ranitidine in preventing duodenal ulcer recurrence, with comparable tolerability for long-term therapy.
