ABSTRACT: Background
Randomized trials and observation studies have revealed conflicting results regarding the interaction between clopidogrel and proton pump inhibitors (PPIs). The aim of our study was to provide laboratory evidence regarding whether PPIs blunt the antiplatelet reactivity of clopidogrel.Methods
We included records of Asian patients who received clopidogrel treatment for cardiovascular or cerebrovascular events and the VerifyNow P2Y12 assay for platelet reactivity monitoring. The responsiveness of antiplatelet effect to clopidogrel was analyzed according to 3 criteria:Results: Patients treated without PPIs did not differ significantly from those concomitantly treated with PPIs in terms of levels of PI (25.7% ± 24.3% vs 23.0 ± 25.3%, P?=?.4315), PRU (187.3 ± 74.0 vs 197.4?±?77.3, P?=?.3373), or responsiveness to antiplatelet (adjusted absolute risk, 3.5%; 95% confidence interval,?-?10.7 to 17.7%; P?=?.6297). Patients treated with lansoprazole, esomeprazole, pantoprazole, and rabeprazole exhibited no significant differences in PRU or PI levels compared with those treated without PPIs. By contrast, patients treated with dexlansoprazole exhibited a significantly decreased level of PI (25.7%?±?24.3% vs 14.0%?±?21.6%, P?=?.0297) and responsiveness to clopidogrel under the criterion PI > 20% (adjusted absolute risk: 10.5%; 95% confidence interval: 2.6% to 43.6%; P?=?.0274).Conclusion
No robust interaction between clopidogrel and PPIs was found, but caution should be exercised in the concomitant use of dexlansoprazole and clopidogrel in Asians.
