Doxycycline-based quadruple regimen versus routine quadruple regimen for rescue eradication of Helicobacter pylori: an open-label control study in Chinese patients.

Abstract

Quadruple therapy containing doxycycline is as effective as routine quadruple therapy for H. pylori rescue eradication. The regimen is well tolerated by most patients and causes fewer adverse events than routine quadruple therapy. Hence, it may be recommended as a suitable alternative H. pylori rescue regimen in China.
