Randomized Controlled Trial Clinical TrialSalvage therapies after failure of Helicobacter pylori eradication with ranitidine bismuth citrate-based therapies.
Salvage therapies after initial Helicobacter pylori eradication failure of ranitidine bismuth citrate (RBC)-based regimens remain undefined. ⋯ One-week OAC is not an optimal second-line therapy when RBC-clarithromycin combinations fail. Quadruple therapy appears to be effective despite repeated failures of clarithromycin-based RBC or proton pump inhibitor therapies.
