Helicobacter Pylori and Vonoprazan Dual Therapy

Summary

Our previous study included 119 Helicobacter pylori(H. pylori)-infected Chinese patients without previous eradication history who were randomized to low-or high-dose amoxicillin-vonoprazan regimens consisting of amoxicillin 1 gram either b.i.d. or t.i.d plus vonoprazan 20 mg b.i.d for 7 or 10 days. Neither 7-or 10-day VA dual therapy with either b.i.d. or t.i.d. amoxicillin achieved satisfied efficacy (i.e., \<90%) when given as first-line treatment for H. pylori infection. This study evaluated the efficacy and safety of low-and high-dose amoxicillin-vonoprazan dual therapy for 14 days as first-line treatment for H. pylori in China.
