ATC Group: A14A Anabolic steroids
Anatomical Therapeutic Chemical Classification System
Methenolone is an anabolic steroid, modification of dihydrotestosterone (DHT) with weak androgenic activity and a moderate anabolic effect. Methenolone esters are used mainly in the treatment of anemia due to bone marrow failure.
Nandrolone is chemically related to testosterone and shows enhanced anabolic and a reduced androgenic activity. In humans nandrolone has been shown to positively influence calcium metabolism and to increase bone mass in osteoporosis.
Oxymetholone is a 17alpha-alkylated anabolic-androgenic steroid and a synthetic derivative of testosterone. It has been approved for the treatment of anemias caused by deficient red cell production. Acquired aplastic anemia, congenital aplastic anemia, myelofibrosis and the hypoplastic anemias due to the administration of myelotoxic drugs often respond.
Prasterone, i.e. dehydroepiandrosterone (DHEA), biochemically and biologically identical to the endogenous human DHEA, is a precursor steroid which is inactive by itself and it is converted into oestrogens and androgens. Intrarosa is thus different from the oestrogens preparations since it delivers also androgen metabolites.
