Drugbank ID : DB00025
Protein chemical formula : C11794H18314N3220O3553S83
Protein average weight :
Half life : hrs

2. Description : Indication : Pharmacodynamics :
Human recombinant antihemophilic factor (AHF) or Factor VIII, 2332 residues, glycosylated, produced by CHO cells
Indication :
For the treatment of hemophilia A, von Willebrand disease and Factor XIII deficiency.
Pharmacodynamics :
Antihemophilic Factor binds factor IXa along with calcium and phospholipid, This complex converts factor X to factor Xa to facilitate clotting cascade.

3. Mechanism of action : Clearance :
Antihemophilic factor (AHF) 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 (classical hemophilia).
Clearance :
* 4.1 mL/h.kg [Previously treated pediatric patients]

6. Brands : Advate
Description : Advate contains antihemophilic factor, a naturally occurring protein in the blood that helps blood to clot.Advate works by temporarily raising levels of factor VIII in the blood to aid in clotting.
Used for/Prescribed for : ADVATE is a medicine used to replace clotting factor (factor VIII or antihemophilic factor) that is missing in people with hemophilia A (also called "classic" hemophilia). ADVATE is used to prevent and control bleeding in adults and children (0-16 years) with hemophilia A.
Form : powder form
Route of administration : intravenous injection
Dosage : Dose (IU) = body weight (kg) × Desired Factor VIII Rise (IU/dL or % of normal) × 0.5 (IU/kg per IU/dL). So example, assuming assuming patient's baseline Factor VIII level is < 1% of normal = A dose of 1750 IU ADVATE administered to a 70 kg patient should be expected to result in a peak post-infusion Factor VIII increase of 1750 IU × {[2 IU/dL]/[IU/kg]}/[70 kg] = 50 IU/dL (50% of normal).

7. Contraindication : ADVATE is contraindicated in patients who have life-threatening hypersensitivity reactions, including anaphylaxis, to mouse or hamster protein or other constituents of the product. Side effects : chest pain; easy bruising, increased bleeding episodes; or bleeding from a wound or where the medicine was injected.
