A randomized controlled comparison of three quadruple therapy regimens in a population with low <i>Helicobacter pylori</i> eradication rates

Abstract

The omeprazole/clarithromycin/bismuth/tetracycline-based quadruple therapy provides higher H. pylori eradication rates than the ranitidine/metronidazole/bismuth/tetracycline-based quadruple therapy when administered per protocol. The prolongation of the latter regimen from 2 to 3 weeks did not increase eradication rates.
