Interaction Study of Clopidogrel 300/75 mg Given Alone or Concomitantly With Omeprazole 80 mg 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 Concomitantly With Omeprazole 80 mg/Day 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 concomitantly with omeprazole 80 mg/day compared to given alone in healthy male and female subjects
Secondary Objective:
- Compare the pharmacokinetic profiles of clopidogrel and its active metabolite when clopidogrel is given either alone or concomitantly with omeprazole
