About

Erythropoiesis-stimulating agents (ESAs) are recombinant forms of human erythropoietin, a glycoprotein hormone primarily produced by the kidneys. Erythropoietin plays a critical role in erythropoiesis by stimulating the proliferation and differentiation of erythroid progenitor cells in the bone marrow, leading to increased red blood cell production. ESAs are clinically utilized to manage anemia associated with various conditions, including chronic kidney disease, myelosuppressive chemotherapy, and certain surgical procedures, thereby reducing the necessity for red blood cell transfusions and improving patient outcomes. This therapeutic intervention helps to restore adequate oxygen-carrying capacity, alleviating symptoms such as fatigue and shortness of breath, and enhancing overall patient well-being and functional status.
