Food Effect Study on Pharmacodynamic and Bioavailability of Clopidogrel 300/75 mg in Healthy Subjects
A Randomized, Placebo-controlled, Two-sequence, Two-period Crossover Study, to Investigate a Potential Food Effect on the Pharmacodynamic and Bioavailability of Repeated Oral Doses of Clopidogrel (300 mg Loading Dose Followed by 75 mg/Day) in Healthy Male Subjects
Primary objective:
- Investigate the potential food effect on Adenosine diphosphate(ADP)-induced platelet aggregation after 5-day repeated doses of clopidogrel (300 mg loading dose followed by 4 days 75 mg/day) in healthy subjects
Secondary objectives are to investigate the potential food effect on:
- ADP-induced platelet aggregation after 300 mg loading dose of clopidogrel
- Pharmacokinetic profiles of clopidogrel and its active metabolite after 5-day repeated doses of clopidogrel
