Von Willebrand factor (vWF) is a large multimeric glycoprotein important in hemostasis. It mediates platelet adhesion to sites of vascular injury and serves as a carrier protein for coagulation factor VIII. Plasma-derived and recombinant vWF products are used primarily in the treatment and prevention of bleeding episodes in patients with von Willebrand disease, a congenital or acquired bleeding disorder. vWF is an approved drug for clinical use today.
Pharmacokinetics
Pharmacokinetics in adults with severe von Willebrand disease following intravenous administration of plasma-derived von Willebrand factor concentrate (e.g., Wilate), using a one-compartment model.
