Abstract
One hundred and twenty patients with gastric ulcer disease, who had been receiving maintenance treatment with ranitidine (150 or 300 mg/day) for periods up to 7 years, were studied retrospectively. The proportion of patients remaining free from symptomatic recurrence of ulcer during maintenance treatment was 97% after 1 year; 90% after 3 years; and 79% after 5 years. No patient developed haemorrhage or perforation during maintenance treatment. None of the demographic features was shown to be associated with a significantly increased risk of ulcer recurrence during maintenance treatment. Comparison of the recurrence rates during maintenance treatment with those during periods without active anti-ulcer therapy, using life table and incidence density analysis, showed a significant difference in favour of maintenance treatment. We conclude that maintenance treatment with ranitidine for 5 years significantly reduces the risk of symptomatic ulcer recurrence in patients with gastric ulcer.
