Quadruple therapy with ecabet sodium, omeprazole, amoxicillin and metronidazole is effective for eradication of Helicobacter pylori after failure of first-line therapy (KDOG0201 Study).

BACKGROUND AND OBJECT

An antiulcer agent, ecabet sodium, is active against Helicobacter pylori. The aim of the present study was to clinically examine whether eradication therapy, which includes ecabet sodium, is effective in eradication of H. pylori after failure of first-line therapy.

METHODS

Patients with peptic ulcer who failed with first-line triple eradication therapy containing clarithromycin received quadruple therapy with omeprazole (20 mg, twice daily), amoxicillin (750 mg, twice daily), metronidazole (500 mg, twice daily) and ecabet sodium (1000 mg, twice daily) for 14 days. Eradication of H. pylori was judged by 13C-urea breath test 8 weeks later.

RESULTS

Fifty-two patients (36 men and 16 women) were included. Their mean age was 51.4 years (range 28-73). One patient dropped out because of diarrhoea. The eradication rate was 98.0% (50/51) according to the per-protocol analysis and 96.2% (50/52) according to the intention-to-treat analysis. Side effects occurred in seven patients, but none were serious.

CONCLUSIONS

Quadruple therapy including ecabet sodium is useful as second-line eradication treatment for H. pylori.
