Cost-effectiveness of cimetidine maintenance therapy in chronic gastric and duodenal ulcer

The effects of cimetidine maintenance therapy on the socioeconomic life of patients with peptic ulcers in the 3 years after healing and the extent to which treatment was cost-effective were studied. Three hundred eleven patients with healed ulcers (184 gastric, 127 duodenal) were studied for periods of up to 3 years; 261 patients (152 gastric ulcer, 109 duodenal ulcer) completed the 3-year follow-up. Cimetidine (400 mg at night) was compared with placebo in a double-blind, randomized prospective study. Intention-to-treat analysis was used. In the placebo group, the major costs of ulcer disease in gastric ulcer patients were attributable to endoscopic procedures and absenteeism; in duodenal ulcer patients, the major costs were endoscopic procedures, absenteeism, and surgery. Cimetidine was cost-effective in both gastric ulcer and duodenal ulcer patients in the first 2 years after healing. Over the 3-year period it was also cost-effective, but no benefit was seen in the third year.
