Verifynow platelet testing clopidogrel nonresponders
Feature | Nicole Fornell, Pharm D

Patients with 2C19 that is less active due to loss of gene copies are poor metabolizers of clopidogrel, opening patients to the possibility of a higher rate of mayocardial infacrtion (MI). There are assays for platelet function response (VerifyNow) and genetic tests to measure patient response, which could help determine if generic clopdogrel or more expensive agents should be used.

Ticagrelor, Brillinta, is the newest antiplatelet agent on the market. Ticagrelor is a reversible nonthienopyridine P2Y12 receptor antagonist that prevents signal transduction and platelet activation.
Feature | Antiplatelet and Anticoagulation Therapies | Nicole Fornell, Pharm D

The standard-of-care for dual antiplatelet therapy (DAPT) for more than a decade has been clopidogrel (Plavix) plus aspirin. This standard is now being challenged by new agents — ticagrelor (Brilinta) and prasugrel (Effient). While the new agents are more effective at preventing platelet aggregation than clopidogrel, each has unique characteristics. Plavix went generic earlier this year, which may also impact decisions about which therapies to use.

August 23, 2012 — Decision Resources, a research and advisory firm for pharmaceutical and healthcare issues, finds that the 12-month post-hospital acute coronary syndrome market will initially contract from just under $2 billion in 2011 to about $1.6 billion in 2013, mainly as a result of the U.S. genericization of clopidogrel (Bristol-Myers Squibb/Sanofi’s Plavix) in 2012. Decision Resources forecasts that the post-hospital acute coronary syndrome antiplatelet/anticoagulant market will then expand to almost $2.7 billion in 2021, owing largely to uptake of oral agents with novel modes of action, such as AstraZeneca’s ticagrelor (Brilinta) and the CETP inhibitors, Merck’s anacetrapib and Eli Lilly’s evacetrapib.
