Randomized Controlled Trial Multicenter Study Comparative StudyComparison of antiplatelet efficacy and tolerability of clopidogrel napadisilate with clopidogrel bisulfate in coronary artery disease patients after percutaneous coronary intervention: a prospective, multicenter, randomized, open-label, phase IV, noninferiority trial.
Clopidogrel bisulfate, a potent antiplatelet agent, has a pivotal role in the prevention and treatment of atherothrombotic disease. Clopidogrel napadisilate, a different salt preparation of clopidogrel, has been developed and approved in Korea and several European countries. Recent studies have suggested that clopidogrel napadisilate might have improved stability and comparable bioequivalence to clopidogrel bisulfate. However, these 2 clopidogrel preparations have not been compared in terms of efficacy and tolerability in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI). ⋯ In this study of CAD Korean patients who have undergone PCI, the antiplatelet efficacy of clopidogrel napadisilate was noninferior to that of clopidogrel bisulfate after 4 weeks of maintenance treatment. No statistically significant difference was found in tolerability between the 2 treatment groups.
