BACKGROUND: In a pilot study, ranitidine bismuth citrate (RBC; Pylorid, Tritec) in coprescription with clarithromycin achieved a Helicobacter pylori eradication rate (based on 13C urea breath test alone) of 83%. The aim of the current study was to validate this finding by using three diagnostic tests and a larger group of H. pylori-positive patients with active duodenal ulcer.
METHODS: In a blinded study, 95 patients were given either 4 weeks of treatment with RBC, 400 mg bid, alone (RBC400, n = 31) or RBC, 400 mg bid or 800 mg bid, in coprescription with clarithromycin, 250 mg qid for 14 days, followed by 14 days of RBC, 400 mg bid, alone (RBC400 + CLAR and RBC800 + CLAR, respectively; n = 32 for each). Rates of ulcer healing at week 4 and of H. pylori eradication (assessed by antral and corpus urease tests and histology and by 13C urea breath test) at week 8 were compared, together with the incidence of adverse events.
RESULTS: All three regimens were effective at duodenal ulcer healing and were tolerated well. The coprescription regimens gave significantly higher observed H. pylori eradication rates (82% and 74% for RBC400 + CLAR and RBC800 + CLAR) compared with RBC400 (0%; p < .001).
CONCLUSIONS: RBC in dual therapy with clarithromycin provides excellent H. pylori eradication therapy and is an effective duodenal ulcer healing drug.
