Must be given with IV Vitamin K concurrently when used for warfarin reversal. Intracerebral haemorrhage (ICH) is the most devastating and disabling type of stroke. In patients with concern for increasing intravascular volume, PCC (although costly) is less volume. Reversal of factor Xa inhibitor direct oral anticoagulants in patients who require urgent procedure (if andexanet alfa unavailable) (off-label use): Note: Reversal agent should be administered only if the procedure cannot safely be performed while the patient is anticoagulated or cannot be delayed (Cuker 2019). A more recent trial looked at reversal of apixaban and rivaroxaban in emergency bleeding events with PCC and found that 70.2% of patients had reversal while 30.9% did not; 32% died within 30 days, and overall the patients had low VTE rate . Available in the US: Kcentra. Kcentra is indicated for the urgent reversal of acquired coagulation factor deficiency induced by vitamin K antagonists in the setting of acute major bleeding. Kcentra dosing varies according to the patientâs baseline INR and body weight (initial dose recommended as 25-50 IU/kg for significant bleeds). Argatroban (Novostan) is an intravenous direct thrombin inhibitor indicated as an alternative to heparin in patients suspected of developing heparin-induced thrombocytopenia with thrombosis (HIT). Dabigatran has the only commercially available reversal agent, idarucizumab, which is a human monoclonal antibody fragment that neutralizes the anticoagulant effect of dabigatran by binding to the drug.
