Interaction Study of Clopidogrel 300/75 mg Given Alone or With Omeprazole 80 mg 12 Hours Apart in Healthy Subjects
A Randomized, Placebo-controlled, Two-period, Two-treatment, Two Sequence, Cross-over Pharmacodynamic and Pharmacokinetic Interaction Study After 5-days Repeated Oral Doses of Clopidogrel (300 mg Loading Dose Followed by 75 mg/Day) Alone or Given With Omeprazole 80 mg/Day (12 Hours Apart on the Same Days) in Healthy Male and Female Subjects
Primary objective:
- Assess the effects of clopidogrel (300 mg loading dose followed by 4 days 75 mg/day) on Adenosine diphosphate (ADP)-induced platelet aggregation when given either alone in the morning, or in association with omeprazole 80 mg/day in the evening at a 12-hours interval in healthy male and female subjects
Secondary Objectives:
- Compare the pharmacokinetic profiles of clopidogrel and its active metabolite when clopidogrel is given either alone alone in the morning, or in association with omeprazole in the evening at a 12-hours interval
