Is It Time for Antiplatelet Therapy to Enter Personalized Medicine?
Since its approval in 1997, clopidogrel has been a cornerstone of therapy in patients with acute coronary syndrome (ACS) and those undergoing percutaneous coronary intervention (PCI) to reduce future ischemic events. Although the drug has led to significantly better outcomes, high variability in the antiplatelet effect has been demonstrated. A number of factors are responsible for this variability as demonstrated through pharmacodynamic and pharmacokinetic studies, including clinical factors and the presence of CYP2C19 loss-of-function alleles and reduced metabolism of clopidogrel to its active metabolite leading to attenuation of the intended anti-platelet effect [Brandt JT et al. J Thromb Haemost 2007]. See summary: Is It Time for Antiplatelet Therapy to Enter Personalized Medicine?
