Anticoagulant
Anticoagulants are "agents that prevent blood clotting".[1] They may be used to prevent embolism and thromboembolism.
Vitamin K antagonists
Warfarin
Warfarin is a commonly used oral anticoagulant that interferes with the Vitamin K dependent coagulation co-factors.
Heparin
Details of the usage of heparin are available in clinical practice guidelines by the American College of Chest Physicians[2]:
Direct thrombin inhibitors
Direct thrombin inhibitors bind directly to thrombin.[3]
- Argatroban is for treating heparin-induced thrombocytopenia (HIT)
- Bivalirudin is a recombinant protein
- Dabigatran
- Desirudin
- Hirudin is a recombinant protein for treating heparin-induced thrombocytopenia (HIT)
- Lepirudin
- Ximelagatran is a recombinant protein that is an oral direct thrombin inhibitor
Factor Xa inhibitors
Idraparinux is a synthetic derivative of heparin that has a long half life that allows once-weekly dosage. A randomized controlled trial compared idraparinux to warfarin and found that idraparinux is equivalent for deep venous thrombosis but is inferior for pulmonary embolism.[4]
Warfarin combined with heparin
Warfarin combined with heparin did not benefit survivors of acute myocardial infarction in a randomized controlled trial.[5]
