Summary

Dual therapy for Helicobacter pylori refers to a treatment regimen that combines two agents: a potent acid suppressor (such as a proton pump inhibitor \[PPI\] or a potassium-competitive acid blocker \[PCAB\]) and the antibiotic amoxicillin. This approach is increasingly recognized as a viable alternative to traditional triple or quadruple therapies, particularly in the context of rising resistance to other antibiotics such as clarithromycin and metronidazole. Potent acid suppression increases the stability and activity of amoxicillin against H. pylori by maintaining a higher gastric pH, which is essential for optimal amoxicillin effect. High-dose dual therapy (e.g., amoxicillin 1,000 mg three times daily + standard dose of PPI three or four times daily for 14 days) has demonstrated eradication rates of 90%. In 2015, vonoprazan, a novel P-CAB, was launched in Japan and used as an alternative for PPIs for eradicating H. pylori. Dual therapy with vonoprazan and amoxicillin is particularly effective, with cure rates comparable to triple therapy and superior outcomes in clarithromycin-resistant infections. Dual therapy is generally well tolerated, with adverse event rates similar to or lower than those seen with triple or quadruple regimens. In 2018, a new P-CAB, tegoprazan, was developed in Korea and approved for H. pylori eradication. However, there was no study of tegoprazan and amoxicillin dual therapy for the treatment of H. pylori.
