Bismuth quadruple regimen with tetracycline or doxycycline versus three‐in‐one single capsule as third‐line rescue therapy for <i>Helicobacter pylori</i> infection: Spanish data of the European <i>Helicobacter pylori</i> Registry (Hp‐EuReg)

Abstract

Third-line H pylori eradication with bismuth quadruple treatment (after failure with clarithromycin and levofloxacin) offers acceptable efficacy and safety. Highest efficacy was found in compliant patients and those taking 10-day BQT-three-in-one or 14-day BQT-Tet. Doxycycline seems to be less effective and therefore should not be recommended.
