To compare the efficacy and safety of Tegoprazan-amoxicillin dual therapy and bismuth quadruple therapy based on furazolidone in the treatment of Helicobacter pylori eradication, the eradication rate, patient compliance, and adverse drug reactions of H. pylori infection were compared in a multi-center clinical joint study in Jiangsu Province.

This study is a prospective, multicenter, open-label, randomized, parallel-controlled study. A total of 600 Hp-positive patients who had not received Hp eradication therapy before or who had previously eradicated Hp but had not undergone eradication therapy in the past six months were recruited, and the basic clinical data of the patients (age, gender, drug allergy history, diagnosis and treatment, etc.) were recorded, and they were randomly divided into two groups according to the ratio of 1:1. Group A subjects received oral Tegoprazan 50mg, bid + amoxicillin 1000mg, tid; Group B subjects received oral Tegoprazan 50 mg, bid + amoxicillin 1000 mg, bid + furazolidone 100 mg, bid + colloidal pectin bismuth 300 mg, bid. The duration of treatment is 14 days.

During the 14-day eradication treatment period, all participants were asked to record their adverse reactions and adherence to the medication. On the 7th and 14th days of medication, the researchers will conduct follow-up visits through WeChat or telephone to determine the adverse reactions and compliance of the patients, and observe and record whether the subjects have nausea, diarrhea, dizziness, bitter mouth, rash, constipation and other adverse reactions. In addition, subjects returned to the hospital 4-6 weeks after the end of treatment to check for H. pylori eradication by 13C-UBT or 14C-UBT.
