NCT00942175

Brief Summary

The purpose of this study is to assess the potential effect and safety of multiple oral doses of dexlansoprazole, lansoprazole, omeprazole or esomeprazole, once daily (QD), on the steady-state pharmacokinetics and pharmacodynamics of clopidogrel, and to assess the safety of multiple doses of clopidogrel in healthy participants.

Outcome Measures

Primary Outcomes (5)

  • Pharmacokinetic Parameter Peak Plasma Concentration (Cmax) of Clopidogrel's Active Metabolite.

    Maximum observed plasma concentration (Cmax) is the peak plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.

    Day 9 of each period

  • Pharmacokinetic Parameter Area Under the Plasma Concentration Versus Time Curve (AUC) From Time 0 to Time of the Last Quantifiable Concentration (AUC[0-tlqc]) of Clopidogrel's Active Metabolite.

    Area under the plasma concentration versus time curve (AUC(0-tlqc)) is a measure of total plasma exposure to the drug from Time 0 to Time of the Last Quantifiable Concentration (AUC\[0-tlqc\]).

    Day 9 of each period

  • Pharmacodynamic Parameter Platelet Reactivity Index (PRI) From Vasodilator-stimulated Phosphoprotein (VASP) Phosphorylation State (Flow Cytometry).

    PRI is the platelet reactivity index from VASP phosphorylation state (flow cytometry).

    24-hour post Day 9 dose in each period.

  • Pharmacodynamic Parameter Maximum Platelet Aggregation (MPA) From Aggregometry (Turbidimetric) With 5 µM Adenosine Diphosphate.

    Maximum platelet aggregation (MPA) from aggregometry (turbidimetric) with 5 µM adenosine diphosphate.

    24-hour post Day 9 dose in each period.

  • Pharmacodynamic Parameter MPA From Aggregometry (Turbidimetric) With 20 µM Adenosine Diphosphate.

    MPA from aggregometry (turbidimetric) with 20 µM adenosine diphosphate.

    24-hour post Day 9 dose in each period.
