Amoxycillin resistance is one reason for failure of amoxycillin–omeprazole treatment of <i>Helicobacter pylori</i> infection

Abstract

The effectiveness of amoxycillin-omeprazole dual therapy was greatly reduced in the presence of pre-treatment amoxycillin-resistant H. pylori. The success rate in patients with amoxycillin-sensitive H. pylori was only 66%, suggesting the presence of additional factors affecting the efficacy of this therapy.
