Comparison of the Efficacy Between the Dual Therapy of Tegoprazan and the Quadruple Therapy of Tegoprazan: A Randomized Controlled Multicenter Study
Abstract
INTRODUCTION: Tegoprazan (TPZ), a potassium-competitive acid blocker, exerts a strong acid-suppression effect and a rapid onset of action. However, research on TPZ-amoxicillin (TA) dual treatment is limited. Here, we compared the safety and efficacy of TPZ-amoxicillin dual treatment and TPZ, bismuth potassium citrate, amoxicillin, and clarithromycin (TBAC) quadruple therapy in patients newly diagnosed with H. pylori infection over a 14-day treatment period.
METHODS: A total of 236 patients newly diagnosed with H. pylori were enrolled in this multicenter, prospective, open-label, and randomized controlled study. Patients randomly received either TA dual or TBAC quadruple therapy. The incidence of adverse reactions and treatment compliance were recorded and then analyzed.
RESULTS: The intention-to-treat analysis revealed that H. pylori eradication rates were 83.9% (95% confidence interval 78.2%-91.3%) and 81.4% (95% confidence interval 74.2%-88.5%) for the TA and TBAC groups, respectively, with no statistically significant difference between them ( P = 0.606). The per-protocol analysis revealed that the H. pylori eradication rates were 88.3% and 84.8% for the TA and TBAC groups, respectively ( P = 0.447). The incidence of adverse reactions was significantly lower in the TA group than in the TBAC group (4.2% vs 15.3%, P = 0.004). Moreover, the TA group demonstrated substantially higher treatment compliance than the TBAC group (94.1% vs 89.0%, P = 0.020).
DISCUSSION: The TA dual…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 236 participants or records.
