Pharmacodynamic and Pharmacokinetic Study of 2 Different Dose Regimen of Clopidogrel in CYP2C19 Genotyped Healthy Subjects
A Randomized, Double-blind, Double-dummy, Two Period, Two Treatment Cross-over Pharmacodynamic and Pharmacokinetic Study of Clopidogrel Given as 5-day Repeated Oral Doses (300 mg Loading Dose Followed by 75 mg/Day and 600 mg Loading Dose Followed by 150 mg/Day) in 4 Different Groups of CYP2C19 Genotyped Healthy Male and Female Subjects
Primary Objective:
- Investigate the possible role of the CYP2C19 genotype in Adenosine diphosphate (ADP)-induced platelet aggregation after administration of a standard dose regimen of clopidogrel (300 mg loading dose followed by 75 mg/day for 4 days) in healthy male and female subjects
Secondary Objectives:
- Assess the pharmacodynamic activity of a higher dose regimen of clopidogrel (600 mg loading dose followed by 150 mg/day for 4 days)
- Compare the pharmacokinetic profiles of clopidogrel active metabolite between the selected groups of genotyped subjects and the 2 dose regimen
