Mechanism of action

Epoetin alfa is a glycoprotein that mimics endogenous erythropoietin, a hormone produced by the kidneys that regulates red blood cell formation. By binding to erythropoietin receptors on erythroid progenitor cells in the bone marrow, it promotes their proliferation, differentiation, and maturation into mature red blood cells. The once-weekly formulation allows for less frequent dosing while maintaining therapeutic erythropoiesis.
