Reversal of Dabigatran Effects in Models of Thrombin Generation and Hemostasis by Factor VIIa and Prothrombin Complex Concentrate

0 views | Mar 25 2017

Hoffman M et al suggested that a cell-based model reflects the effects on thrombin generation of clinically relevant levels of FVIIa and PCC in the presence of dabigatran. Enhancing the rate of thrombin generation and peak thrombin level appear to correlate best with hemostasis in vivo. The ineffectiveness of FVIIa at supratherapeutic dabigatran levels may explain conflicting reports of its efficacy in dabigatran reversal. [Read the Full Post]
