Background and Aim: Many studies have reported poor results with standard first‐line treatment for Helicobacter pylori . Second‐line regimens that may overcome bacterial resistance can minimize side‐effects and optimize compliance. The aim of this study was to evaluate the efficacy of proton pump inhibitor (PPI) and bismuth subcitrate‐based quadruple therapy, after failure of a PPI plus clarithromycin and amoxicillin as first‐line therapy. Methods: Patients who failed to eradicate the infection after initial therapy were randomly separated into three groups. The first group received lansoprazole, bismuth subcitrate, metronidazole and amoxicillin (LBMA); in the second group metronidazole was replaced by tetracycline (LBTA); and the third group was given metronidazole and tetracycline in addition to same doses of lansoprazole and bismuth subcitrate (LBMT). Results: In the LBMA group, the eradication rate was 74.7% and was significantly related to sex, with no relationship to age. In the LBTA group the eradication rate was 81.5% with similar rates in males and females. No relation to sex or age was observed. In the LBMT group the eradication rate was 82.1% with no difference between women and men and it was not related to age, either. Eradication rates in study groups were similar ( P > 0.05). Conclusion: A‐14‐day regimen of lansoprazole, bismuth subcitrate and antibiotic pairs, tetracycline–amoxicillin and tetracycline–metronidazole, is an effective quadruple therapy after one failed course of standard triple therapy. The evaluation of tolerability of and compliance with quadruple therapy needs further studies.
