Effect of ZaStaprazan on Platelet Reactivity of Clopidogrel After PercuTaneous CoronAry InteRvention
brief summary
The purpose of this study is to evaluate the clinical utility of zastaprazan compared to proton pump inhibitors (PPIs) in patients receiving dual antiplatelet therapy (DAPT) including clopidogrel after percutaneous coronary intervention (PCI), by comparing their effects on platelet reactivity.
detailed description
This study aims to evaluate the impact of zastaprazan on platelet reactivity when co-administered with clopidogrel and to identify differences in potential drug-drug interactions compared to conventional Proton Pump Inhibitors (PPIs). Through this, we intend to propose an optimal combination strategy that simultaneously addresses antiplatelet efficacy and gastrointestinal protection.
Notably, as rabeprazole is known to have a lower degree of CYP2C19 inhibition among PPIs, this study will specifically compare zastaprazan with rabeprazole to evaluate and confirm the comparative effects on platelet reactivity.
