Factor IX concentrate is a medication used to treat and prevent bleeding in individuals with hemophilia B, a genetic disorder caused by a deficiency of Factor IX, a protein essential for blood clotting. This concentrate is derived from human plasma or produced using recombinant DNA technology, ensuring a high concentration of the active factor. Patients typically receive Factor IX concentrate through intravenous infusion, allowing for rapid absorption into the bloodstream. The treatment helps to restore the missing factor, enabling proper clot formation and reducing the risk of bleeding episodes during surgeries or after injuries.
