Obizur is generally used for the treatment of serious bleeding episodes in patients with acquired hemophilia A. The bleeding episode may occur due to trauma or surgery.
Indeed, antihemophilic factor recombinant porcine sequence is a manmade protein which is preferably used to replace the AHF produced naturally in the body. It is required for clot formation and maintenance of hemostasis.
Acquired hemophilia A, also called classic hemophilia, is a clinical disorder that develops in such conditions where the body fails to make enough AHF. If you do not have enough AHF and you become injured, the clot formation will be impaired.
You might bleed into and damage your muscles and joints. That’s why this injection is given to increase the levels of AHF in the blood.
This product is available in powder form which is used for preparing a solution. You will get this drug only with your doctor's prescription.
