Dual Therapy With Vonoprazan Plus Amoxicillin or Doxycycline Versus Bismuth Quadruple Therapy for Helicobacter Pylori Eradication.

Dual Therapy With Vonoprazan Plus Amoxicillin or Doxycycline Versus Bismuth Quadruple Therapy for Helicobacter Pylori Eradication:A Prospective, Multicenter, Open-label Randomized Controlled Study

It is planned to select Hp infection patients in a number of tertiary hospitals in Jiangsu and randomly divide them into three groups: group A is the classic group, receiving Vonoprazan 20mg, bid + amoxicillin 1.0g, bid + doxycycline 0.1g, bid + colloidal pectin bismuth 0.3g, bid and group C are double groups, respectively, receiving standard dose amoxicillin (1.0 g, bid) combined with vonorrasan dual regimen and doxycycline (0.1g, bid) combined with Vonoprazan dual regimen, the treatment course of the three groups was 14 days, and the oral dose of Vonoprazan was 20mg, bid, the eradication rate, adverse reactions, compliance and other aspects of the three groups were compared, In order to obtain a safe, efficient, economical and convenient Hp eradication program with a wider range of applications.
