In the PENTHIFRA-Plus trial, after an initial one-week prophylaxis with fondaparinux, 656 hip fracture surgery patients were assigned to an additional 3 weeks of treatment with a once-daily subcutaneous injection of either 2.5 mg of fondaparinux or placebo. 16 Fondaparinux reduced the incidence of VTE from 35.0% in the placebo group to 1.4% (3/208 patients), a relative risk reduction of 95.9%

FONDAPARINUX FOR THE TREATMENT OF ACUTE CORONARY SYNDROMES (ACS)

Fondaparinux is also used together with warfarin (Coumadin, Jantoven) … Andexanet alfa, an antidote that rapidly reverses the anticoagulant activity of all factor Xa inhibitors (UFH, LMWH, fondaparinux, and direct factor Xa inhibitors such as rivaroxaban, apixaban and edoxaban) has shown efficacy in clinical trials, but is not yet approved by Health Canada. fondaparinux (UWMedicine: fondaparinux assay [FNDXT]) (Arixtra) 17-21 hours (significantly longer in renal impairment) NO Fondaparinux levels can be assessed by anti-factor Xa activity Consider rFVIIa (Novoseven) 90 mcg/kg NOTE: rVIIa will not effect anti-factor Xa … ARIXTRA (fondaparinux sodium) Injection is a sterile solution containing fondaparinux sodium. It is a synthetic and specific inhibitor of activated Factor X (Xa). Studies in which r-Antidote is administered repeatedly to patients with long-term follow up will be needed to address concerns regarding the generation of r-Antidote-specific antibodies or crossreactive antibodies to native fX or fXa.The anticoagulant activity of LMWH and fondaparinux is mediated by ATIII, which is an irreversible inhibitor of serine proteases of the coagulation cascade. 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 2020-08-01 At the recommended dose, Fondaparinux does not affect fibrinolytic activity or bleeding time.

g. heparins or fondaparinux. Fondaparinux is a synthetic analog of the antithrombin-binding pentasaccharide sequence that differs from LMWH in several ways. As a synthetic analog of the antithrombin-binding pentasaccharide sequence found in heparin and LMWH, fondaparinux binds only to antithrombin and is too short to bridge thrombin to antithrombin (see Fig. 7-4). There is no specific antidote for fondaparinux: it is not neutralised by protamine sulphate. Fondaparinux shows no cross-reactivity with antibodies associated with heparin-induced thrombocytopenia. Subsequently, question is, what is the antidote for warfarin?

Jun 23, 2015 Clinical evidence to support the use of individual antidotes is currently rivaroxaban) and injectable indirect (e.g., enoxaparin, fondaparinux) 

To make the use of fondaparinux safer, we developed an antithrombin (AT) variant as a potent antidote to heparin derivatives.

The anti-factor Xa assay may be used to monitor therapy in special populations such as those with renal impairment or who are 2012-12-02 · The effect of r-Antidote was mediated by reducing plasma anti-fXa activity and the non–protein bound fraction of the fXa inhibitor in plasma. In rats, r-Antidote administration dose-dependently and completely corrected increases in blood loss resulting from ATIII-dependent anticoagulation by enoxaparin or fondaparinux. r-Antidote has 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.

Fondaparinux is a new heparin derivative that has become increasingly important in clinical medicine due to its advantages over current anticoagulants. However, there is no antidote currently There is no specific antidote for fondaparinux: it is not neutralised by protamine sulphate. Fondaparinux shows no cross-reactivity with antibodies associated with heparin-induced thrombocytopenia. Subsequently, question is, what is the antidote for warfarin?

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. Fondaparinux is a new heparin derivative that has become increasingly important in clinical medicine due to its advantages over current anticoagulants.
