What are blood thinners?

Anticoagulants and platelet inhibitors (aka blood thinners) cause your blood to take longer to clot, which can reduce the risk of strokes and heart attacks that can occur when blood clots get stuck in small blood vessels. Blood thinners include the following group of drugs (generic drug names are listed in lowercase letters):

  • dalteparin sodium (Fragmin)
  • enoxaparin (Lovenox)
  • fondaparinux (Arixtra)
  • heparin sodium
  • warfarin (Coumadin)
Platelet inhibitors:
  • aspirin
  • cilostazol (Pletal)
  • clopidogril bisulfate (Plavix)
  • dipyramidamole (Persantine)
  • prasugrel (Effient)
  • ticagrelor (Brilinta)
  • ticlopidine (Ticlid)
Direct thrombin inhibitor:
  • dabigatran (Pradaxa)
Factor Xa inhibitors:
  • rivaroxaban (Xarelto)
  • apixaban (Eliquis)

The term "blood thinner" generally refers to drugs such as warfarin (Coumadin), Plavix, or aspirin, all of which have the property of reducing the clotting time of the blood and preventing the formation of blood clots.
