Prothrombin complex concentrate (PCC, trade names Beriplex, Octaplex, Kcentra, Cofact, among others) is a combination of blood clotting factors II, VII, IX and X, as well as protein C and S, prepared from fresh-frozen human blood plasma. It is used to reverse the effects of oral anticoagulation therapy when bleeding occurs (e.g. in the brain or gut) requiring rapid action to accelerate coagulation.
PCC is effective but expensive. In the UK, it is prescribed in discussion with a haematologist. It is available as a powder and solvent for solution for injection.
PCC reverses the effect of warfarin and other coumarin anti-coagulants and is used in cases of significant bleeding in patients with a coagulopathy (INR > 8.0, prolonged prothrombin time). It is also used when such a patient must undergo an emergency operation treatment. Other indications include a deficiency of one of the included clotting factors, either congenital or due to liver disease, and hemophilia.
The package insert states that PCC is contraindicated in patients with disseminated intravascular coagulation, a pathological activation of coagulation, because giving clotting factors would only further fuel this process. However, if the PCC is given because factor levels are low, it can restore normal coagulation. As PCC products contain heparin, they are contraindicated in patients with heparin-induced thrombocytopenia.
The U.S. Food and Drug Administration (FDA) announced its approval of Kcentra on April 30, 2013. The FDA approved Kcentra's orphan drug status in December 2012.
