DescriptionHuman recombinant antihemophilic factor or Factor VIII of 2332 residues(glycosylated) is produced by CHO cells.
Indication/DiseaseFor the treatment of hemophilia A, von Willebrand disease and Factor XIII deficiency.
PharmacodynamicsAntihemophilic Factor binds factor IXa along with calcium and phospholipid, this complex converts factor X to factor Xa to facilitate clotting cascade.
Mechanism of ActionAntihemophilic factor is a protein found in normal plasma which is necessary for clot formation. The administration of AHF provides an increase in plasma levels of AHF and can temporarily correct the coagulation defect of patients with hemophilia A.
ToxicityThe highest toxicity is the risk of viral hepatitis transmition as well as intravascular hemolyisis can occur if large or frequent doses are used in blood groups A, B or AB
MetabolismThe metabolism of the human antihemophilic factor is identical to the normal inactivation and elimination pathway of the natural coagulation factor VIII. After activation, the human antihemophilic factor gets metabolized by activated protein C in R336 and R562 and this action inactivates this cofactor. The proteolysis generates two major fragments which are recognized by an anti-factor VIII A2 domain antibody. This process is followed by a further degradation into smaller fragments
AbsorptionAfter intravenous administration of the human antihemophilic factor the values of Cmax, AUC and Tmax were 100 IU/ml, 1450 IU h/ml and 0.43 h respectively. In a second clinical trial, the treatment was administered for six months and the values of Cmax, AUC and Tmax were 99 units/ 100 ml, 1471 units h/ 100ml and 16 h, respectively.
The central and peripheral volume of distribution in adults weight an average of 68 kg were 2.81 L and 1.90 L respectively.
Clearance0.15 L/h
