What Is Advate (Antihemophilic Factor [Recombinant])?

Advate is an FDA-approved medicine used to treat children and adults with bệnh máu khó đông A. In people with hemophilia A, the blood does not clot as it should. 

What Is Advate?

Advate is a brand-name prescription medication. The active medication in this product is recombinant clotting factor VIII. You may also call it a recombinant antihemophilic factor. It belongs to a class of medicines called antihemophilic factors. The term “recombinant” means Advate is made with recombinant DNA technology. 
Recombinant clotting factors are not derived from blood. Therefore, Advate is not a blood product and does not carry the risk of spreading blood-borne viruses. 
People with hemophilia A have little or no clotting factor VIII in their blood. Clotting factor VIII helps your body form blood clots. Factor VIII deficiency can lead to spontaneous, uncontrolled internal bleeding, which can be fatal. 
Các FDA initially approved Advate to control and prevent bleeding episodes in hemophilia A in 2003.
