Comparison of 3-Factor Versus 4-Factor Prothrombin Complex Concentrate With Regard to Warfarin Reversal, Blood Product Use, and Costs

摘要

Background: Prothrombin complex concentrates (PCCs) are drug products containing varying amounts of vitamin K-dependent coagulation factors II, VII, IX, and X. The evidence comparing 3-factor PCC (3-PCC) versus 4-factor PCC (4-PCC) for warfarin reversal is conflicting. It has been hypothesized that 3-PCC may be less effective than 4-PCC because of relatively lower factor VII content.
