Effective hemostasis measured up to 24 hours for the Acute Major Bleeding trial and until the end of procedure (up to 24 hours) for the Urgent Surgery/Invasive Procedures trial. Rapid INR reduction to ≤1.3 at 0.5 hours after end of infusion.

How long does it take Kcentra to work?
A single Kcentra infusion produced a rapid and sustained increase in plasma levelsof clotting factors II, VII, IX, and X within 30 minutes post-treatment (p values<0.0001) with 87 percent less volume (105 mL +/-37 mL versus 865 mL +/- 269 mL) than plasma.
Should vitamin K be given with Kcentra?
Administer Vitamin K concurrently to patients receiving Kcentra. Vitamin K is administered to maintain Vitamin K-dependent clotting factor levels once the effects of Kcentra have diminished. The safety and effectiveness of repeat dosing have not been established and it is not recommended.
Can Kcentra be repeated?
In general, a single dose is given; dosing may be repeated in rare situations in which the oral anticoagulant persists for longer in the circulation, such as severe kidney dysfunction.
Is Kcentra a blood product?
Because Kcentra is made from human blood, it may carry a risk of transmitting infectious agents, e.g., viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent, and, theoretically, the Creutzfeldt-Jakob disease agent. There is also the possibility that unknown infectious agents may be present in such products.
Is Kcentra FDA approved?
The U.S. Food and Drug Administration (FDA) announced its approval of Kcentra (Prothrombin Complex Concentrate) on April 30. The drug, a first-in-class therapy, is used for urgent vitamin K antagonist (VKA) anticoagulation reversal in adult patients with acute major bleeding.
Does Kcentra reverse Coumadin?
— The FDA has approved Kcentra for the urgent reversal of vitamin K antagonist anticoagulation in adults with acute major bleeding, according to the agency.
Does Kcentra reverse eliquis?
Cofact may be partially beneficial in the reversal of the anticoagulant effect of apixaban. Kcentra currently is the only nonactivated 4F‐PCC available in the United States, and could potentially have some activity against apixaban induced anticoagulation, but has not been systematically evaluated.
When is Kcentra used?
Kcentra (prothrombin complex) is a blood coagulation factor replacement product. Kcentra is used to quickly reverse the effects of a blood-thinning medicine (such as warfarin) during a major bleeding episode, or when there is a need for emergency surgery or invasive medical procedure.
Can you reverse rivaroxaban?
Andexanet alfa is a recombinant form of human factor Xa protein which binds specifically to apixaban or rivaroxaban, thereby reversing their anticoagulant effects.
What percentage of patients on an anticoagulant will experience a major bleeding event?
Major bleeding during anticoagulant treatment remains a crucial issue, with estimated incidences ranging from 2 to 3% in clinical trials [6] to up to 4% in observational post-marketing studies [14].
Can FFP reverse heparin?
Vitamin K, and in emergency conditions, PCC, or FFP can be used for warfarin reversal, whereas protamine sul- fate reverses the effects of heparin completely. Fondaparinux and LMWH do not have effective reversal agents; however, protamine (for LMWH) and rFVIIa or activated PCC (for fon- daparinux) may have some value.
Does protamine reverse Lovenox?
The anticoagulant effect of LOVENOX is inhibited by protamine. This effect may be largely neutralized by slow intravenous injection of protamine sulfate. However, even with higher doses of protamine, the aPTT may remain prolonged to a greater extent than usually seen with unfractionated heparin.
What is the half life of Kcentra?
Half-life. Median terminal half-life of coagulation factors II, VII, IX, and X following single dose of Kcentra in healthy individuals was 59.7, 4.2, 16.7, and 30.7 hours, respectively.
How is Kcentra calculated?
A single dose of Kcentra is determined by the patient’s pretreatment INR and weight. *Dosing is based on body weight. Dose based on actual potency is stated on the vial, which will vary from 20–31 Factor IX units/mL after reconstitution. The actual potency for 500 unit vial ranges from 400–620 units/vial.
