Effects of rosuvastatin on platelet inhibition by clopidogrel in cardiovascular patients

J Thromb Thrombolysis. 2009 Aug;28(2):151-5. doi: 10.1007/s11239-008-0254-6. Epub 2008 Jul 18.


Statin interference has been suggested among the mechanisms of reduction of the antiplatelet effect of clopidogrel. We thus sought to assess the influence of rosuvastatin on clopidogrel antiplatelet action in high-risk (HR) cardiovascular patients. To set the level of platelet inhibition by combined antithrombotic treatments we retrospectively studied two populations of HR patients, one under aspirin alone, the other under aspirin plus rosuvastatin, before and after addition of clopidogrel. The effects of rosuvastatin compared with atorvastatin were then prospectively investigated in patients who underwent percutaneous coronary intervention (PCI), under clopidogrel and aspirin treatment. Light transmission platelet aggregation (LTA) was studied in response to adenosine diphosphate (ADP) (5 microM) or arachidonic acid (0.5 mM). The inhibitory effect of clopidogrel in reducing ADP-induced LTA was similar in the two HR groups of patients. No difference in ADP-induced platelet aggregation was observed in the two PCI groups of patients with either atorvastatin or rosuvastatin. In conclusion, rosuvastatin does not interfere with the antiplatelet effect of clopidogrel in patients with cardiovascular disease.
