One week triple therapy with omeprazole, clarithromycin and tinidazole for <i>Helicobacter pylori</i>: differing efficacy in previously treated and untreated patients

Abstract

One-week low-dose triple therapy with OCT is highly effective as an initial therapy in eradicating H. pylori infection. The efficacy is significantly lower when given as a second line treatment in patients who have previously failed to eradicate H. pylori with bismuth-based standard triple therapy.
