Patients being treated with Vitamin K antagonists VKA therapy have underlying disease states that predispose them to thromboembolic events.

Potential benefits of reversing VKA should be weighed against the potential risks of thromboembolic events TEespecially in patients with the history of a thromboembolic event. Resumption of anticoagulation should be carefully considered as soon as the risk of thromboembolic events outweighs the risk of acute bleeding. Source Plasma 21 CFR Factor IX is the lead factor for the potency of the preparation as stated on the vial label. The excipients are human antithrombin III, heparin, human albumin, sodium chloride, and sodium citrate.

Kcentra is sterile, pyrogen-free, and does not contain preservatives. The product contents are shown in Table 7 and listed as ranges for the blood coagulation factors. Only plasma that passed virus screening is used for production. Table 8 shows the virus clearance during the manufacturing process for Kcentra, expressed as the mean log10 reduction factor.

Virus Reduction Factors [log10] of Kcentra. Studies using human parvovirus B19, which are considered experimental in nature, have demonstrated a virus reduction factor of 3.

Clinical pharmacology Mechanism of Action: 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.

Factor Xa forms a complex with activated FV FVa that converts prothrombin to thrombin in the presence of phospholipids and calcium ions. Protein C, when activated by thrombin, exerts an antithrombotic effect by inhibiting FVa and FVIIIa leading to a decrease in thrombin formation, and has indirect profibrinolytic activity by inhibiting plasminogen activator inhibitor Kcentra, Prothrombin Complex Concentrate Humanis a blood coagulation factor replacement product indicated for the urgent reversal of acquired coagulation factor deficiency induced by Vitamin K antagonist VKA, e.

The most serious ARs were thromboembolic events including stroke, pulmonary embolism, and deep vein thrombosis. No human or animal data.

Resumption of anticoagulation should be carefully considered as soon as the risk of thromboembolic events outweighs the risk of acute bleeding Both fatal and non-fatal arterial and venous thromboembolic complications have been reported with Kcentra in clinical trials and post marketing surveillance.

Monitor patients receiving Kcentra for signs and symptoms of thromboembolic events. Kcentra was not studied in subjects who had a thromboembolic event, myocardial infarction, disseminated intravascular coagulation, cerebral vascular accident, transient ischemic attack, unstable angina pectoris, or severe peripheral vascular disease within the prior 3 months.

Kcentra may not be suitable in patients with thromboembolic events in the prior 3 months. Kcentra is contraindicated in: Patients with disseminated intravascular coagulation DIC. Patients with known heparin-induced thrombocytopenia Kcentrx.

If necessary, discontinue administration and institute appropriate treatment. Arterial and venous thromboembolic complications have been reported in patients receiving Kcentra. Kcentra was not studied in subjects who had a thrombotic or thromboembolic TE event within the prior 3 months. Kcentra is made from human blood and may carry a risk of transmitting infectious agents, e.

Measurement of INR prior to treatment and close to the time of dosing is important because coagulation factors may be unstable in patients with acute major bleeding or an urgent need for surgery and other invasive procedures.

Administer Vitamin K concurrently to patients receiving Kcentra. Vitamin K is administered to maintain Vitamin K-dependent clotting factor levels once the pavkage of Kcentra have diminished. The safety and effectiveness of repeat dosing have not been established and is not recommended. Dose ranging within pre-treatment INR groups has not been studied in randomized clinical trials of Kcentra.

Nominal potency is or units per vial, approximately 25 units per mL after reconstitution.
