    Product Description

    Fondaparinux is a pentasaccharide inhibitor of Factor Xa, the enzyme that activates prothrombin in the coagulation cascade (IC50s = 40, 45, and 36 nM for human, rabbit, and rat enzymes, respectively, in vitro).1 It binds to antithrombin III (Kds = 48, 132, 78, and 50 nM for human, rabbit, baboon, and rat, respectively) and inhibits thrombin generation through the extrinsic and intrinsic routes (IC50s = 0.3 and 2.8 µM, respectively). Fondaparinux dose-dependently inhibits thrombus formation in a rabbit model of venous thrombosis with complete inhibition of clot formation at a dose of 200 µg/kg. Formulations containing fondaparinux have been used for prophylaxis of deep vein thrombosis following hip or knee replacement surgery.
