Superiority of ticagrelor, comparing with clopidogrel (PLATO Trial) - rate of death and overall major bleeding
"...patients who had an acute coronary syndrome with or without ST-segment elevation, treatment with ticagrelor, as compared with clopidogrel, significantly reduced the rate of death from vascular causes, myocardial infarction, or stroke, without an increase in the rate of overall major bleeding but with an increase in the rate of non–procedure-related bleeding..." (Wallentin et al., 2009)
Cost-effectiveness of ticagrelor, as single and combo (with ASA), comparing with clopidogrel
"...12 months of ACS treatment using ticagrelor/ASA instead of clopidogrel/ASA may offer a cost-effective therapeutic option, even when the generic price for clopidogrel is employed." (Theidel, Asseburg, Giannitsis & Katus, 2013)
"Ticagrelor is a clinically superior and cost-effective option for the prevention of thrombotic events among ACS patients in Canada." (Grima et al., 2014)
