Inhibition of platelet aggregation [IPA] evaluated in healthy subjects to treatment with either vicagrel or clopidogrel
Timeframe: Day1-Day31
To compare IPA following multiple doses of vicagrel and/or clopidogrel in healthy subjects with different CYP2C19 phenotypes.
Platelet reactivity index [PRI] evaluated in healthy subjects to treatment with either vicagrel or clopidogrel
Timeframe: Day1-Day31
To compare PRI following multiple doses of vicagrel and/or clopidogrel in healthy subjects with different CYP2C19 phenotypes.
maximum plasma concentration (Cmax)
Timeframe: Day1-Day31
To compare Cmax following multiple doses of vicagrel and/or clopidogrel in healthy subjects with different CYP2C19 phenotypes.
Area under the curve over a dosing interval(AUC0-tau)
Timeframe: Day1-Day31
To compare AUC0-tau following multiple doses of vicagrel and/or clopidogrel in healthy subjects with different CYP2C19 phenotypes.
Assess the safety and tolerability of multiple doses of both drugs in each CYP2C19 phenotype group.
Timeframe: Day1-Day31
