Prothrombin complex concentrate (PCC) is used to boost thrombin potential, support clot formation, and aid in the treatment and prophylaxis of bleeding. The two main forms of PCC are three-factor (3 F-PCC; comprising coagulation factors II, IX, and X) and four-factor (4F-PCC; factors II, VII, IX, X), which contain 25 times the clotting factors found in human plasma. This narrative review summarizes published efficacy and safety data on one 4F-PCC (Octaplex/Balfaxar, Octapharma) within its recognized uses and explores potential applications across different clinical contexts. Clinically available for > 20 years, Octaplex/Balfaxar is supplied as a freeze-dried powder for reconstitution and intravenous infusion. This 4F-PCC contains non-activated forms of coagulation factors as well as anticoagulant proteins C and S, potentially affording a balanced hemostatic effect and mitigating thrombosis risk. Production involves two virus inactivation/removal steps: solvent/detergent treatment and nanofiltration. 4F-PCC is approved for acquired deficiency of vitamin K-dependent clotting factors, such as those induced by vitamin K antagonists (VKAs, e.g., warfarin), and for congenital deficiency of factors II and X. Five published trials in 444 adult patients demonstrated the efficacy of 4F-PCC in VKA reversal, reducing the international normalized ratio (INR) with only two potentially treatment-related thrombotic events reported. While 4F-PCC dosing is currently indicated to be INR-guided, emerging evidence supports fixed dosing as an alternative to conventional weight-based dosing for VKA reversal. Recent guidelines support 4 F-PCC use for direct oral anticoagulant-associated bleeding, cardiac surgery and trauma/emergencies. Ongoing studies will further clarify the efficacy and safety of 4 F-PCC beyond its approved indications.
