Mechanism of action

Epoetin alfa is a biosynthetic form of human erythropoietin (EPO), a hormone that regulates red blood cell production. It binds to EPO receptors on erythroid progenitor cells in the bone marrow, promoting their proliferation and differentiation into mature red blood cells. This increases hemoglobin levels and oxygen-carrying capacity in patients with anemia.
