Abstract

Background: More convenient therapies are needed to treat Helicobacter pylori infection successfully. Clarithromycin and amoxycillin are effective against H. pylori both in vivo and in vitro. Recent success with a high dose amoxycillin‐metronidazole combination therapy led us to evaluate clarithromycin‐amoxycillin dual therapy for H. pylori infection. Methods: We tested the combination of clarithromycin 500 mg t.d.s. with meals plus amoxycillin 750 mg t.d.s. with meals for 10 days for its effect on H. pylori infection in 29 patients with documented H. pylori peptic ulcers. There were 27 men and 2 women, ranging in age from 23 to 77 years. H. pylori and ulcer status were evaluated at entry and at least 4 weeks after ending antimicrobial therapy. For ulcer healing, ranitidine 300 mg was given each evening for 6 weeks. H. pylori status was determined by CLOtest and histology. Results: H. pylori infection was cured in 86% (95% CI = 78–99%). Compliance averaged 93% by pill count. Ten patients (34%) experienced mild side effects: eight reported dysgeusia and two had mild diarrhoea; none discontinued therapy because of side effects. Conclusion: We conclude that dual therapy with clarithromycin and amoxycillin is a safe and effective alternative regimen for the successful treatment of H. pylori infections.
