This change accelerates its inhibition of activated factor X in conversion of prothrombin to thrombin. Although direct binding of andexanet to UFH, enoxaparin, and fondaparinux is also observed, nevertheless, the relatively weak binding (K d = 34-110 µM) of andexanet to any of these heparins (in the absence of AT) suggests this interaction is not the physiological mechanism of action for the reversal of AT-dependent anticoagulant by andexanet. The average maximum plasma anti-Xa activity is reached 3 to 5 hours after a subcutaneous injection.9,12 A 30 mg IV bolus preceding an immediate 1 mg/kg SC every twice a day led to maximum anti-Factor Xa levels of 1.16 IU/mL.
