Uses for factor ix fc fusion protein recombinant
Factor IX Fc fusion protein recombinant injection is used as an on-demand treatment to control or prevent bleeding episodes, prevent bleeding during surgery, or reduce the frequency of bleeding episodes in patients with hemophilia B (congenital Factor IX deficiency).
Factor IX is a protein that is produced naturally in the body. Alprolix® is a man-made protein produced to replicate the naturally occurring factor IX in the body. It is used to stop bleeding by helping the blood to clot in patients with hemophilia B.
