Does NOT contain von Willebrand Factor and is not indicated for the treatment of bleeding in von Willebrand’s disease.
What is factor 8 concentrate?
In 1992, the U.S. Food and Drug Administration (FDA) approved recombinant factor VIII (8) concentrate, which does not come from human plasma.

What is the proper dosing of factor VIII FVIII concentrate for the treatment of hemophilia a?
The dosage needed is commonly given as 25-40 U kg(-1) three times weekly for FVIII or twice weekly for FIX. However, these guidelines are valid only with several qualifications. First, the actual trough levels required may vary considerably between patients.
Which antifibrinolytic drug increases the plasma concentration of Factor VIII and von Willebrand factor?
Desmopressin (DDAVP) Desmopressin (1-deamino-8-d-arginine vasopressin, DDAVP) is a synthetic vasopressin analogue. The drug increases VWF and FVIII plasma levels by releasing VWF from Weibel-Palade bodies in the endothelium [7]. Due to this effect, it is the most widely used drug in the treatment of VWD.
Which blood product is indicated to replace clotting factors?
Fresh frozen plasma is indicated for the deficiency of coagulation factors with abnormal coagulation tests in the presence of active bleeding.
What is Factor 8 medication?

How is VWF synthesized?
vWF is synthesized as monomers that are processed into dimers in the RER. vWF is either constitutively secreted or stored in Weibel-Palade bodies in endothelial cells or in alpha granules in megakaryocytes and platelets. 18. Previous studies have indicated that both FN and vWF are synthesized in megakaryocytes.
