ATC Group: G03BA 3-oxoandrosten (4) derivatives

Fluoxymesterone is a synthetic androgen. Endogenous androgens are responsible for the normal growth and development of the male sex organs and for maintenance of secondary sex characteristics. Fluoxymesterone is used for replacement therapy in conditions associated with a deficiency or absence of endogenous testosterone.

Testosterone, secreted by the testes and its major metabolite dihydrotestosterone (DHT), is responsible for the development of the external and internal genital organs and for maintaining the secondary sexual characteristics (stimulating hair growth, deepening of the voice, development of the libido); for a general effect on protein anabolism; for development of skeletal muscle and body fat distribution; for a reduction in urinary nitrogen, sodium, potassium, chloride, phosphate and water excretion.
