Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary objective:

* Assess the effects of clopidogrel (600 mg loading dose followed by 4 days 150 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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The total study duration per subjects is 8 - 9 weeks broken down as follows:

* Screening: 2 to 21 days before the first dosing (clopidogrel or omeprazole)
* Period clopidogrel/placebo: 7 days including 5 days treatment
* Period clopidogrel/placebo + omeprazole: 12 days including 10 days treatment
* Washout between periods: at least 14 days after last dosing with respect to clopidogrel treatment
* End of study: 7 to 10 days after the last dosing
