Recombinant activated factor VII (rFVIIa) (NovoSeven®, Novo Nordisk, Bagsvaerd, Denmark) was originally developed to treat bleeding in haemophiliacs with antibodies to factor VIII and IX.1 2 At present, rFVIIa is approved in the European Union for this indication and also for the treatment of bleeding in FVII deficiency and Glanzmann thrombasthenia refractory to platelet transfusions.
FVIIa normally circulates in minute quantities and binds to tissue factor (TF) expressed by the damaged vascular bed. The TF-FVIIa complex on TF-bearing cells activates FIX and FX. FXa remains in close proximity to TF-bearing cells and activates FV. The FXaFVa complex on TF-bearing cells rapidly converts small amounts of prothrombin into thrombin.1 3 This initial small amount of thrombin activates platelets, FVIII, FV and FXI. On the surface of activated platelets, FVIIIa and FIXa gather to activate large quantities of FX which finally (in conjunction with FVa) will result in the large thrombin burst which enables
