Drug Mode of Action ::  

Fondaparinux, a synthetic pentasaccharide, acts as a selective inhibitor of activated factor X. It works by binding selectively to ATIII, and potentiates the neutralisation of Factor Xa. This will interrupt the blood coagulation cascade and inhibit both thrombin formation and thrombus development. At the recommended dosage, fondaparinux does not affect fibrinolytic activity or platelet function. It cannot lyse established thrombi and does not affect clotting function tests (e.g. aPPT, INR).

Drug Interactions ::

Increased risk of bleeding w/ (e.g. desirudin, fibrinolytic drugs, glycoprotein IIb/IIIa-receptor antagonists, heparin, heparinoids or LMWH).
