Direct Thrombin Inhibitors
List of authors.Direct thrombin inhibitors (DTIs) are a new class of anticoagulants that bind directly to thrombin and block its interaction with its substrates. Four parenteral DTIs have been approved by the FDA — hirudin and argatroban for heparin-induced thrombocytopenia, bivalirudin as an alternative to heparin in percutaneous coronary intervention, and desirudin as prophylaxis against venous thromboembolism in hip replacement. This article discusses the clinical data on this important new class of medications.
