Prothrombin complex concentrate (human)

What is Prothrombin complex concentrate (human)?

• Prothrombin complex concentrate (human) (KCENTRA) is a blood coagulation factor replacement product used for the urgent reversal of acquired coagulation factor deficiency.

What are the uses of this medicine?

This medicine is used for the urgent reversal of acquired coagulation factor deficiency induced by Vitamin K antagonist (VKA, e.g., warfarin) therapy in adult patients with:

• acute major bleeding or
• need for an urgent surgery/invasive procedure.

How does this medicine work?

• KCENTRA contains the Vitamin K-dependent coagulation Factors II (FII), VII (FVII), IX (FIX), and X (FX), together known as the Prothrombin Complex, and the antithrombotic Protein C and Protein S.
• A dose-dependent acquired deficiency of the Vitamin K-dependent coagulation factors occurs during Vitamin K antagonist treatment.

Vitamin K antagonists exert anticoagulant effects by blocking carboxylation of glutamic acid residues of the Vitamin K-dependent coagulation factors during hepatic synthesis, lowering both factor synthesis and function.

• The administration of KCENTRA rapidly increases plasma levels of the Vitamin K-dependent coagulation Factors II, VII, IX, and X as well as the antithrombotic Proteins C and S.

Who Should Not Use this medicine ?

This medicine cannot be used in patients:

• with known anaphylactic or severe systemic reactions to KCENTRA or any components in KCENTRA including heparin, Factors II, VII, IX, X, Proteins C and S, Antithrombin III and human albumin.

What drug interactions can this medicine cause?

• No formal drug interaction studies have been conducted with KCENTRA.

How should this medicine be used?

• KCENTRA dosing should be individualized based on the patient's baseline International Normalized Ratio (INR) value, and body weight.
• Administer Vitamin K concurrently to patients receiving KCENTRA to maintain factor levels once the effects of KCENTRA have diminished.

Recommended Dosage:

• Administer reconstituted KCENTRA at a rate of 0.12 mL/kg/min (~3 units/kg/min) up to a maximum rate of 8.4 mL/min (~210 units/min).

Reconstituted KCENTRA solution should be colorless, clear to slightly opalescent, and free from visible particles. Do not use if the solution is cloudy, discolored, or contains particulates.
• Use aseptic technique when administering KCENTRA.
• Administer at room temperature.
• Administer by intravenous infusion at a rate of 0.12 mL/kg/min (~3 units/kg/min), up to a maximum rate of 8.4 mL/min (~210 units/min).
