fondaparinux, it may be an option in eminent life threatening bleeding when other modalities have not been successful. ~ 12 hr Fresh Frozen Plasma (FFP) Replaces coagulation factors lowered by warfarin. Contains all coagulant factors, including II, VII, IX, and X but in diluted inactive form compared to other options. Onset: ~ 1-4 hours

There is no antidote for fondaparinux. Protamine sulfate has no effect on the anticoagulant activity of fondaparinux, because it fails to bind to the drug. Recombinant activated factor VII reverses the anticoagulant effects of fondaparinux in volunteers, but it is unknown whether this agent will control fondaparinux-induced bleeding.

Unfortunately, there is no easy way for healthcare providers to counteract the effects of this type of overdose. ARIXTRA® (fondaparinux sodium) Injection is a sterile solution containing fondaparinux sodium. It is a synthetic and specific inhibitor of activated Factor X (Xa). guideline provides reversal recommendations for the following: warfarin, oral and intravenous direct thrombin inhibitors, oral anti-Xa inhibitors, heparin-based medications, fondaparinux, NSAIDs, P2Y12 ASP receptor inhibitors, phosphodiesterase inhibitors and glycoprotein IIb/IIIa inhibitors. Reversal Agents in Development • Aripazine • small molecule • binds to and inhibits heparin, LMWH, fondaparinux, direct FXa inhibitors, direct thrombin inhibitor • may require different doses for reversal of Apixaban and Rivaroxaban • unclear mechanism of action Thromb Haemost 2015;113:931-942. Degree of reversal can be assessed with PTT and/or plasma-diluted thrombin time (UWMedicine: DTI assay [DTIPAT]) betrixaban (Bevyxxa) 19-27 hours (longer in renal impairment) Unknown There is no assay for betrixaban at this time.

Idarucizumab 5 grams (two 2.5g vials) Xa Inhibitors Apixaban (Eliquis) ® Reverse if patient shows signs of life threatening bleeding 1. Fondaparinux (Arixtra) is a synthetic anticoagulant based on the pentasaccharide sequence that makes up the minimal antithrombin (AT) binding region of heparin. Similar to low molecular weight heparins, it is an indirect inhibitor of factor Xa, but it does not inhibit thrombin at all. Consider 1) holding fondaparinux until bleeding resolves; 2) reduction in dosing; and/or 3) increase in dosing interval: Serious or life threatening bleeding: Requires inpatient admission Follow UW Medicine guidelines for reversal of anticoagulation and management of bleeding ARIXTRA (fondaparinux sodium) Injection is a sterile solution containing fondaparinux sodium.

The synthetic polymer HBSPCM (Heparin Binding Synthetic Polyvalent Cationic Macromolecule) has been found to be a promising candidate antidote for fondaparinux. However, an optimal design of HBSPCM that binds to fondaparinux with high affinity and neutralizes it has not yet been determined.

me Limited possibilities to monitor the effect of NOAC and lack of specific antidotes complicate the management of bleeding patients and in the perioperative setting. Es gibt kein bekanntes Antidot für Fondaparinux.

There is no known antidote that reverses the anticoagulant effects of Fondaparinux. Bleeding complications during therapy or overdosage of Fondaparinux should lead to immediate treatment discontinuation and initiation of appropriate supportive therapy. Fondaparinux lacks specific antidotes and there is no routine laboratory assay for monitoring the efficacy of fondaparinux. Thrombin generation test measures the kinetic of thrombin formation over time which is a more complete characterisation of the individual coagulation capacity than classical clot based assays. Arixtra ® (fondaparinux sodium) is a prescription anticoagulant medication. As with most medications, it is possible to take too much Arixtra. As you might predict, an Arixtra overdose increases the risk of dangerous bleeding.

To make the use of fondaparinux safer, we developed an antithrombin (AT) variant as a potent antidote to heparin derivatives. This variant (AT-N135Q-Pro394) combines 2 mutations: substitution of Asn135 by a Gln to remove a glycosylation site and increase affinity for heparins, and the insertion of a Pro between Arg393 and Ser394 to abolish its anticoagulant activity.

Unfortunately, there is no easy way for healthcare providers to counteract the effects of this type of overdose. 2012-12-02 Fondaparinux is used to prevent a type of blood clot called deep vein thrombosis (DVT), which can lead to blood clots in the lungs (pulmonary embolism).
