NCIt synonyms : Factor Xa Recombinant Inactivated-zhzo; Coagulation Factor Xa (Recombinant), Inactivated-zhzo;
NCIt definition : A genetically modified variant of human factor Xa (FXa) protein, that may be used
to reverse the anticoagulation effect of direct oral FXa inhibitors. Upon intravenous
administration, andexanet alfa binds to the administered FXa inhibitor, thereby neutralizing
the anticoagulant effect of the FXa inhibitor. Andexanet alfa also binds to and inhibits
the activity of tissue factor pathway inhibitor (TFPI), thereby increasing tissue
factor (TF)-initiated thrombin generation and promoting coagulation.;
