Erythropoietin (EPO) is a naturally occurring hormone produced by the kidneys, which plays a crucial role in regulating red blood cell production. EPO stimulates the bone marrow to produce red blood cells, which carry oxygen throughout the body. In patients with chronic kidney disease, anemia, or certain types of cancer, EPO levels may be low, leading to fatigue, weakness, and shortness of breath.

(often referred to as Neoepoetin Patched) is a medical formulation primarily used to treat anemia by stimulating red blood cell production. It functions as an erythropoiesis-stimulating agent (ESA), typically designed for continuous or controlled delivery through a transdermal system. Mechanism of Action
