For treatment of hemorrhagic complications in hemophilia A and B


Used in the treatment of bleeding episodes in hemophilia A or B. NovoSeven is recombinant Factor VIIa and, when complexed with tissue factor can activate coagulation Factor X to Factor Xa, as well as coagulation Factor IX to Factor IXa. Factor Xa, in complex with other factors, then converts prothrombin to thrombin, which leads to the formation of a hemostatic plug by converting fibrinogen to fibrin and thereby inducing local clotting.

mechanism of action

NovoSeven activates the coagulation or clotting cascade by cleaving Factor IX and Factor X, which activates them and then leads to activation of thrombin and fibrin.
