Unfractionated heparin, low molecular weight heparin and vitamin K antagonists are anticoagulants currently used for the prevention and treatment of deep vein thrombosis and pulmonary embolism. Considerable limitations of these agents, such as a narrow therapeutic window, a variable dose response or lack of oral bioavailability, created the need for new anticoagulants. Numerous new compounds with different mechanisms of action have been developed and some have been already approved for clinical use. Quite recently, fondaparinux, an indirect anti-factor Xa inhibitor, has been licensed in Europe and in the US for prevention of VTE in patients undergoing hip or knee replacement surgery. In addition, lepirudin, a recombinant hirudin derivative, and the heparinoid danaparoid, have been approved in Austria for treatment of heparin-induced thrombocytopenia. Recombinant nematode anticoagulant protein c2, the orally available thrombin inhibitor ximelagatran and ART-123, a recombinant soluble thrombomodulin, are in advanced stages of clinical development. This article reviews mechanisms and sites of action, and the current state of preclinical and clinical research of these and various other agents with respect to the prevention and treatment of venous thromboembolism).

Venous thromboembolic disease, including deep vein thrombosis and pulmonary embolism, is a cause of significant mortality and morbidity. In the US, approximately 260000 cases are diagnosed annually. Current drugs for the prevention and treatment of venous thromboembolism (VTE) include heparin, low-molecular-weight heparins and warfarin. Since they possess several disadvantages, researchers are investigating improved anticoagulants. To understand how any promising anticoagulant would work, a review of the pathophysiology and regulation of the coagulation cascade is provided. The more prominent drugs reviewed include tissue factor pathway inhibitor protein, nematode anticoagulant protein, Factor IX inhibitors, anti-Factor Xa inhibitors (DX-9065a (Daiichi Seiyaku Co Ltd), YM-60828 (Yamanouchi Pharmaceutical Co Ltd), fondaparinux, idraparinux (Sanofi-Synthelabo/NV Organon)), selective thrombin inhibitors (oral heparin, ximelagatran (AstraZeneca plc)) and enhancers of natural anticoagulants (activated protein C, ART-123 (Asahi Kasei Pharma Corp)).
