  Purpose

Background:

  • The prevalence of arthritis which needs celecoxib prescription is high in patients with coronary artery disease.
  • The main concern is that celecoxib would increase thrombogenicity by inhibiting the synthesis of prostacyclin in endothelial cells.
  • It is not known whether the administration of celecoxib would deteriorate antiplatelet effects of aspirin and clopidogrel which are used after stenting.

Methods:

  • Healthy volunteers (n=40)
  • Randomization into five subgroups
  • aspirin, celecoxib, aspirin+celecoxib, aspirin+clopidogrel, aspirin+clopidogrel+celecoxib
  • Medication schedule : medication of each drug for 6 days, blood samples at day 0 and day 7
  • Celecoxib 200mg twice a day, and/or aspirin 100mg daily, and/or clopidogrel 75 mg daily
  • Platelet function test : light transmittance aggregometry and arachidonic acid metabolite assay among subgroups.

Study hypothesis : The addition of celecoxib does not deteriorate antiplatelet function of aspirin and clopidogrel.
