What is the primary action of epoetin alfa?

• A. Inhibits red blood cell production
• B. Stimulates white blood cell production
• C. Stimulates red blood cell production
• D. Increases platelet production

Answer: (C)

Epoetin alfa acts as a synthetic erythropoietin, driving the production of red blood cells. It binds to erythropoietin receptors on erythroid progenitor cells in the bone marrow, triggering their proliferation and maturation into mature red blood cells. This directly increases red blood cell mass, hemoglobin, and hematocrit. It is not intended to boost white blood cells or platelets, which is why the other options don’t fit. This is especially useful for treating anemia from chronic kidney disease or certain cancer treatments.
