Abstract
Eighty patients with duodenal ulcer were randomly allocated to treatment with tripotassium dicitrato bismuthate (TDB) tablets or cimetidine. Ulcers healed in 78% of patients treated with TDB and in 74% treated with cimetidine, supporting previous observations that the efficacy of these two agents is similar. Duodenal ulcer recurred in 43% of patients in the 12 months after treatment with TDB and in 78% of patients treated with cimetidine, with a significantly greater incidence of recurrence 6-12 months after cimetidine treatment. Tripotassium dicitrato bismuthate tablets may be preferable to cimetidine in the initial management of duodenal ulcer, because they offer a smaller likelihood of recurrence in the 12 months after successful treatment.
