Outcome Measures

Primary Outcome Measures :

Pharmacodynamics of Ticagrelor on P2Y12 receptor blockade measured by the VerifyNow P2Y12 assay[expressed as P2Y12 reaction units (PRU)] [ Time Frame: Day 1 pre-dose and at 0 (pre-dose), 1, 2, 8, 12 and 24 hours post morning dose on Day 5 ]
Pharmacodynamics of Clopidogrel P2Y12 receptor blockade measured by the VerifyNow P2Y12 assay[expressed as P2Y12 reaction units (PRU)] [ Time Frame: Day 1 pre-dose and at 0 (pre-dose), 1, 2, 8, 12 and 24 hours post morning dose on Day 5 ]

Secondary Outcome Measures :

Safety profile in terms of adverse events, blood pressure, pulse, ECG (Electrocardiogram), physical examination, and safety laboratory variables [ Time Frame: From screening to followup (8 weeks) ]
