Dr. HONG LU, Shanghai Jiao Tong University School of Medicine
  Purpose
The increase of antibiotic resistance to H. pylori causes failure of treatment. Furazolidone, amoxicillin and tetracycline are good candidates for rescue therapy since resistance to these three antimicrobials was rare. It is necessary to assess the efficacy and safety of these four bismuth-containing quadruple regimens with above antibiotics as empirical rescue therapies for H. pylori eradication.

Condition Intervention Phase
Functional Dyspepsia Scarred Peptic Ulcer Drug: Proton Pump Inhibitor Drug: Bismuth Drug: Metronidazole Drug: Tetracycline Drug: Furazolidone Drug: Amoxicillin Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
