  • Assess the effect of esomeprazole 40 mg, omeprazole 80 mg or lansoprazole 60 mg on the PK profile of clopidogrel active metabolite by assessing the inhibition of platelet aggregation (mIPA). [ Time Frame: Baseline ]
  • Assess the effect of esomeprazole 40 mg, omeprazole 80 mg or lansoprazole 60 mg on the PK profile of clopidogrel active metabolite by assessing the inhibition of platelet aggregation (mIPA). [ Time Frame: Day 2 ]
  • Assess the effect of esomeprazole 40 mg, omeprazole 80 mg or lansoprazole 60 mg on the PK profile of clopidogrel active metabolite by assessing the inhibition of platelet aggregation (mIPA). [ Time Frame: Day 6 ]
  • Assess the effect of esomeprazole 40 mg, omeprazole 80 mg or lansoprazole 60 mg on the PK profile of clopidogrel active metabolite by assessing the inhibition of platelet aggregation (mIPA). [ Time Frame: Day 15 ]
  • Assess the effect of esomeprazole 40 mg, omeprazole 80 mg or lansoprazole 60 mg on the PK profile of clopidogrel active metabolite by assessing the inhibition of platelet aggregation (mIPA). [ Time Frame: Day 30 ]

  • Assess the effect of esomeprazole 40 mg, omeprazole 80 mg or lansoprazole 60 mg on the PK profile of clopidogrel active metabolite by assessing the AUC, AUC 0-t and Cmax after the loading dose of clopidogrel (Day 1) and AUC 0-t, ss and Css, max. [ Time Frame: Days 5,14, 29 ]
  • Evaluate the safety and tolerability of clopidogrel given concomittantly with esomeprazole, omeprazole or lansoprazole by assessment of adverse events and calculation of change from baseline for clinical laboratory tests, vital signs and pECG. [ Time Frame: Every in-house day ]

Study Evaluating Effect of Esomeprazole, Omeprazole or Lansoprazole on the Pharmacodynamics (PD) and Pharmacokinetics (PK) of Clopidogrel
An Open-label, Randomized, 4-treatment, 3-period, Crossover Interaction Study, Evaluating the Effect of Esomeprazole 40 mg, Omeprazole 80 mg or Lansoprazole 60 mg on the Pharmacodynamics and the Pharmacokinetics of Clopidogrel in Healthy Volunteers
The aim of this study is to determine if there is a pharmacological interaction between clopidogrel and different types of proton pump inhibitors (PPIs), and if the extent of this possible interaction would change over time.
