Mechanism of action

Fondaparinux is a synthetic pentasaccharide that binds to antithrombin III, potentiating its inhibition of Factor Xa. By blocking Factor Xa activity, it interrupts the intrinsic and common pathways of the coagulation cascade, preventing the amplification phase of thrombin generation. This results in anticoagulation without direct thrombin inhibition, distinguishing it from unfractionated heparin (UFH) which inhibits both Factor Xa and thrombin.
