Bismuth Improves the Efficacy of Levofloxacin-containing Triple Therapy for Helicobacter Pylori Treatment

Phase 4

Completed

• Conditions: Functional Dyspepsia; Peptic Ulcer
• Interventions: Drug: Lansoprazole; Drug: Bismuth; Drug: Levofloxacin; Drug: Amoxicillin

• Registration Number: NCT01667718
• Lead Sponsor: Shanghai Jiao Tong University School of Medicine

Brief Summary

To examine and compare the efficacy of 2 week Levofloxacin-containing therapies with and without Bismuth for H.pylori treatment.

Detailed Description

The success rate of the standard triple therapy for H. pylori infection is decreasing recently.Fluoroquinolone has been proposed to replace clarithromycin as an alternative in the treatment. However prevalence of H.pylori resistance to Levofloxacin has increased rapidly in our area. The purpose of this study is to observe the efficacy of 14 day Levofloxacin triple therapy-based, bismuth-containing quadruple therapy for H.pylori treatment.
