General information

Class/mechanism: Recombinant inactive FXa, used for specific reversal of DOACs (direct oral anticoagulants) Rivaroxaban (Xarelto) and Apixaban (Eliquis). Coagulation factor Xa (recombinant) inactivated-zheo binds and sequesters rivaroxaban and apixaban, negating their factor Xa inhibiting, anticoagulant effect. It also inhibits Tissue Factor Pathway Inhibitor (TFPI); inhibition of TFPI can increase tissue factor-initiated thrombin generation.[1][2][3]
