Oral Steroid Known as Anabol, Danabol, Averbol, Dianabol, Metandienone, Methandienone 1. PHYSICO-CHEMICAL PROPERTIES Naturally-occuring anabolic steroids are synthesised in the testis, ovary and adrenal gland from cholesterol via pregnenolone. Synthetic anabolic steroids are based on the principal male hormone testosterone, modified in one of three ways: alkylation of the 17-carbon esterification of the 17-OH group modification of the steroid nucleus 1.2 Chemical structure 2.3 Contraindications Known or suspected cancer of the prostate or (in men) breast. Pregnancy or breast-feeding. Known cardiovascular disease is a relative contraindication. 3. ROUTES OF EXPOSURE 3.1 Oral Anabolic steroids can be absorbed from the gastrointestinal tract, but many compounds undergo such extensive first-pass metabolism in the liver that they are inactive. Those compounds in which substitution of the 17- carbon protects the compound from the rapid hepatic metabolism are active orally There are preparations of testosterone that can be taken sublingually. 3.2 Inhalation Not relevant 3.3 Dermal No data available 3.4 Eye Not relevant 3.5 Parenteral Intramuscular or deep subcutaneous injection is the principal route of administration of all the anabolic steroids except the 17-alpha-substituted steroids which are active orally. 4. Pharmacodynamics Anabolic steroids bind to specific receptors present especially in reproductive tissue, muscle and fat. The anabolic steroids reduce nitrogen excretion from tissue breakdown in androgen deficient men. They are also responsible for normal male sexual differentiation. The ratio of anabolic ("body-building") effects to androgenic (virilizing) effects may differ among the members of the class, but in practice all agents possess both properties to some degree. There is no clear evidence that anabolic steroids enhance overall athletic performance.
