title: Roxatidine acetate in the long term maintenance of duodenal ulcers.
abstract: A non-comparative multicentre study of 105 patients with healed duodenal ulcers was conducted to determine the effect on ulcer recurrence of 6 months' maintenance treatment with roxatidine acetate 75 mg daily. All patients had previously received roxatidine acetate treatment. 31 patients out of 89 had 32 relapsed ulcers after 6 months of treatment, which represents an overall relapse rate of around 30%; the relapse rate in smokers was double that of non-smokers. The overall incidence of epigastric pain did not increase significantly over the period of the trial, although some patients complained of mild pain when they entered the study despite having endoscopically confirmed healed ulcers. At the end of the study continuous poor appetite and pyrosis were reported by 17% and 6% of patients, respectively. Side effects, which included constipation and diarrhoea, were reported by 4 patients, 1 of whom withdrew from therapy. There were no clinically significant changes in laboratory values. Thus, maintenance treatment with roxatidine acetate 75 mg daily proved a safe and effective method of preventing symptomatic duodenal ulcer relapse.
