BACKGROUND: One‐week triple therapy consisting of omeprazole 20 mg b.d., clarithromycin 250 mg b.d. and tinidazole 500 mg b.d. is an effective therapy for H. pylori infection with a cure rate of 93%. We therefore compared two similar 1‐week regimens consisting of a lansoprazole, clarithromycin and either metronidazole or tetracycline in a prospective study. METHODS: Two cohorts, each of 60 patients suffering from H. pylori infection associated with peptic ulcer disease or ulcer‐like dyspepsia, were treated for 1 week with either lansoprazole 30 mg b.d., clarithromycin 250 mg b.d. and either metronidazole 400 mg b.d. (cohort A, n = 60) or tetracycline 300 mg b.d. (cohort B, n = 60). Four weeks after treatment, cure of H. pylori infection was evaluated by endoscopy using rapid urease testing together with histology. RESULTS: In cohort A, 55 patients out of 60 showed cure of H. pylori infection (92%); the treatment was well tolerated, but three patients suffered from side‐effects. In cohort B, which was free of metronidazole, 50 out of 60 patients showed cure of H. pylori infection (83%); two patients reported side‐effects. The differences between the two cohorts were not statistically significant. CONCLUSION: Triple therapy for 1 week with lansoprazole as the antisecretory agent seems to be as effective as is reported for omeprazole‐based regimens.
