What is Fondaparinux?

  • Fondaparinux (Arixtra) is a synthetic anticoagulant made up of five monomeric sugar units and an O-methyl group at the molecule's reducing end. When cleaved into monomeric units, it resembles the polymeric glycosaminoglycans heparin and heparan sulphate (HS). Fondaparinux prevents the activity of some blood clotting factors. Deep vein thrombosis (DVT) is a form of blood clot that can lead to blood clots in the lungs. Fondaparinux is used to avoid DVT (pulmonary embolism). Following certain types of surgery, a DVT may develop. DVT, like pulmonary embolism, is treated with fondaparinux in combination with warfarin (Coumadin, Jantoven).
