Fondaparinux Sodium (Org 31540, Natural heparin pentasaccharide, Fondaparin, SR-90107A) is a synthetic glucopyranoside with antithrombotic activity. It selectively binds to antithrombin III, thereby potentiating the innate neutralization of activated factor X (Factor Xa) by antithrombin; a synthetic inhibitor of Factor Xa.
