Vonoprazan and amoxicillin is a combination therapy used mainly for the eradication of Helicobacter pylori infection. Vonoprazan is a potassium-competitive acid blocker (P-CAB) that inhibits gastric acid secretion, while amoxicillin is a broad-spectrum beta-lactam antibiotic. This combination is clinically approved and used, particularly in Asia, for H. pylori eradication regimens as an alternative to traditional proton pump inhibitor-based therapies.
Pharmacokinetic parameters are estimated based on monotherapy data for vonoprazan and amoxicillin in healthy adult subjects, due to lack of published combined PK model data for fixed-dose or co-administered combination.
