Andexxa works by acting as a decoy for oral and injectable Factor Xa inhibitors, which target and bind to Factor Xa, which allows them to exert their anticoagulant effect. Andexxa is a modified form of the human Factor Xa molecule, an enzyme that helps blood clot. Monitor for symptoms and signs that precede cardiac arrest and provide treatment as needed.Īndexxa is a recombinant protein specifically designed to bind to Factor Xa inhibitors and rapidly reverse their anticoagulant effect. Monitor for thromboembolic events and initiate anticoagulation when medically appropriate. Treatment with Andexxa has been associated with serious and life-threatening adverse events, including: Arterial and venous thromboembolic events, Ischemic events, including myocardial infarction and ischemic stroke, Cardiac arrest, Sudden deaths. The Andexxa label comes with the following Boxed Warning: Follow-On IV Infusion: 8mg/min for up to 120 minutes.Īdverse effects associated with the use may include, but are not limited to, the following: High Dose: Initial IV Bolus: 800 mg at a target rate of 30 mg/min. Follow-On IV Infusion: 4mg/min for up to 120 minutes. Administer as an intravenous (IV) bolus, with a target rate of 30 mg/min, followed by continuous infusion for up to 120 minutes.There are two dosing regimens: Low Dose: Initial IV Bolus: 400 mg at a target rate of 30 mg/min 4 mg/min for up to 120 minutes. Dose Andexxa based on the specific FXa inhibitor, dose of FXa inhibitor, and time since the patient’s last dose of FXa inhibitor. As a result, the native Factor Xa is available to participate in the coagulation process and restore hemostasis (normal clotting).Īndexxa is specifically indicated for patients treated with rivaroxaban and apixaban, when reversal of anticoagulation is needed due to life-threatening or uncontrolled bleeding.Īndexxa is supplied as a lyophilized powder for solution for intravenous injection. Adexxa (andexanet alfa) where it works by acting as a decoy for Factor Xa inhibitors in the blood, thereby preventing them from inhibiting the activity of native Factor Xa. Portola Pharmaceuticals has introduced an FDA approved drug Andexxa.
