NCIt definition : A synthetic glucopyranoside with antithrombotic activity. Fondaparinux selectively
binds to antithrombin III, thereby potentiating the innate neutralization of activated
factor X (Factor Xa) by antithrombin. Neutralization of Factor Xa inhibits its activity
and interrupts the blood coagulation cascade, thereby preventing thrombin formation
and thrombus development.;
Alternative definition : NCI-GLOSS: A drug used to prevent blood clots from forming inside blood vessels in
the leg. It is being studied in the prevention of blood clots in some cancer patients,
including women having surgery for cancer of the reproductive tract. It is a type
of anticoagulant.; ACC/AHA: Fondaparinux is a synthetic anticoagulant based on the pentasaccharide sequence
that makes up the minimal antithrombin-binding region of heparin.;
