Abstract BACKGROUND: Helicobacter pylori eradication triple therapy with a combination of lansoprazole, amoxicillin and clarithromycin was approved in Japan in September 2000. AIM: To compare the cost-effectiveness of this eradication therapy with conventional histamine-2 receptor antagonist therapy in Japan. METHODS: We established two Markov models for gastric and duodenal ulcers. The model design was based on the Japanese H. pylori eradication guideline and a specialist's opinions, and the model inputs were obtained from a literature review. The models predict the direct medical costs, number of disease-free days and cost per disease-free day for 5 years. RESULTS: In the gastric ulcer model, the expected total costs of eradication and conventional therapies per patient were yen169 719 and yen390 921, respectively; the expected numbers of disease-free days were 1454 days and 1313 days, respectively. In the duodenal ulcer model, the expected total costs were yen134 786 and yen324 689, respectively; the expected numbers of disease-free days were 1503 days and 1387 days, respectively. The sensitivity analyses showed that the results of the base case analysis were robust. CONCLUSIONS: This eradication therapy is less costly and more effective than conventional therapy for the treatment of gastric and duodenal ulcers in a Japanese medical setting.
