23431 Structure and Mechanism of Action. Fondaparinux is a synthetic pentasaccharide that causes an antithrombin III-mediated selective inhibition of factor Xa. Also seek emergency medical attention if you have symptoms of a spinal blood clot.

An O-methyl modification of the pentasaccharide sequence of heparin that avidly binds to antithrombin and accelerates by 300 times the inactivation of factor Xa. Undergoing epiduralspinal anesthesia or spinal puncture that are anticoagulated or scheduled to be anticoagulated with fondaparinux sodium LMW heparins or. For indications other than acute coronary syndromes such as VTE the full therapeutic anticoagulation dose is 5 mg if weight is 100 kg.

By selectively inactivating factor Xa in an antithrombin-dependent mechanism of action fondaparinux exerts its anticoagulant effect through inhibition of thrombin generation without any direct effect on thrombin activity. The synthetic pentasaccharide fondaparinux is the first in a novel class of antithrombotic agents. By selectively binding to ATIII Fondaparinux potentiates about 300 times the neutralization of Factor.

Dose 25 mg SC q24h Note. Fondaparinux sodium is the first agent of a new class of anticoagulants that selectively target factor Xa. Selective inhibitor of Factor Xa.

It has a molecular weight of 1728 and binds to AT producing conformational change at the reactive site of AT resulting in a 300-fold increase in its inhibitory activity on factor Xa. Get emergency medical help if you have signs of an allergic reaction. Mechanism of action.

Fondaparinux has been associated with a low rate of serum aminotransferase elevations during therapy but has not been implicated in cases of clinically apparent idiosyncratic liver injury. Back pain numbness or muscle weakness in your lower body or loss of bladder or bowel control.

When fondaparinux binds to ATIII a permanent conformation change in the ATIII molecule allows an increased affinity for. Similar to low molecular weight heparins it is an indirect inhibitor of factor Xa but it does not inhibit thrombin at all.
