Description:
Mechanism of Action: Oxymetholone is an anabolic steroid. It is used to treat anaemia (due to bone marrow failure and decreased RBC production) by increasing erythropoietin and stimulating erythropoiesis. It is also a synthetic derivative of testosterone and can suppress the gonadotropic functions of the pituitary. |
