Isomers of 3-hydroxyestran-17-one estrane-3,17-diol were identified by gas-liq chromatography-mass spectrometry in urine of a crossbred horse given 19-nortestosterone im.
Metabolic studies of (14)c-labeled nortestosterone were carried out in mice by macroscopic autoradiog and in calves by liq scintillation determination of excretion and organ distribution. Radioactivity quickly eliminated in urine and feces. 10 wk after admin residual levels were low.
IDENTIFICATION: Nandrolone phenylpropionate is an anabolic steroid. Origin of the substance: 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. Color: The drug is white to creamy white solid crystals with a slight characteristic odor. It is practically insoluble in water; soluble in alcohol. Indications: The only legitimate therapeutic indications for anabolic steroids are: replacement of male sex steroids in men who have androgen deficiency, for example as a result of loss of both testes; the treatment of certain rare forms of aplastic anemia which are or may be responsive to anabolic androgens, or the drugs have been used in certain countries to counteract catabolic states, for example after major trauma. HUMAN EXPOSURE: Main risks and target organs: There is no serious risk from acute poisoning, but chronic use can cause harm. The main risks are those of excessive androgens: menstrual irregularities and virilization in women and impotence, premature cardiovascular disease and prostatic hypertrophy in men. Both men and women can suffer liver damage with oral anabolic steroids containing a substituted 17-alpha-carbon. Psychiatric changes can occur during use or after cessation of these agents. Summary of clinical effects: Acute overdosage can produce nausea and gastrointestinal upset. Chronic usage is thought to cause an increase in muscle bulk, and can cause an exaggeration of male characteristics and effects related to male hormones. Anabolic steroids can influence sexual function. They can also cause cardiovascular and hepatic damage. Acne and male- pattern baldness occur in both sexes; irregular menses, atrophy of the breasts, and clitoromegaly in women; and testicular atrophy and prostatic hypertrophy in men. Contraindications: Known or suspected cancer of the prostate or (in men) breast, pregnancy or breast-feeding, and known cardiovascular disease is a relative contraindication. ROUTES OF EXPOSURE: 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. 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. Absorption by route of exposure: The absorption after oral dosing is rapid for testosterone and probably for other anabolic steroids, but there is extensive first-pass hepatic metabolism for all anabolic steroids except those that are substituted at the 17-alpha position. The rate of absorption from subcutaneous or intramuscular depots depends on the product and its formulation. Absorption is slow for the lipid-soluble esters such as the cypionate or enanthate, and for oily suspensions. Distribution by route of exposure: The anabolic steroids are highly protein bound, and is carried in plasma by a specific protein called sex-hormone binding globulin. Biological half-life by route of exposure: The metabolism of absorbed drug is rapid, and the elimination half-life from plasma is very short. The duration of the biological effects is therefore determined almost entirely by the rate of absorption from subcutaneous or intramuscular depots, and on the de-esterification which precedes it. Metabolism: Free (de-esterified) anabolic androgens are metabolized by hepatic mixed function oxidases. Elimination by route of exposure: After administration of radiolabelled testosterone, about 90% of the radioactivity appears in the urine, and 6% in the feces; there is some enterohepatic recirculation. Mode of action: Toxicodynamics: The toxic effects are an exaggeration of the normal pharmacological effects. 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. Carcinogenicity: Anabolic steroids may be carcinogenic. They can stimulate growth of sex-hormone dependent tissue, primarily the prostate gland in men. Precocious prostatic cancer has been described after long-term anabolic steroid abuse. Cases where hepatic cancers have been associated with anabolic steroid abuse have been reported. Teratogenicity: Androgen ingestion by a pregnant mother can cause virilization of a female fetus. Main adverse effects: The adverse effects of anabolic steroids include weight gain, fluid retention, and abnormal liver function as measured by biochemical tests. Administration to children can cause premature closure of the epiphyses. Men can develop impotence and azoospermia. Women are at risk of virilization. /Nandrolone phenylpropionate/
Anticoagulant effect may be increased during concurrent use with anabolic steroids, especially 17-alpha-alkylated compounds, because of decreased procoagulant factor concentration caused by alteration of procoagulant factor synthesis or catabolism and increased receptor affinity for the anticoagulant; anticoagulant dosage adjustment based on prothrombin time determinations may be required during and following concurrent use. /Anabolic steroids/
Anabolic steroids may decrease blood glucose concentrations; diabetic patients should be closely monitored for signs of hypoglycemia and dosage of hypoglycemic agent adjusted as necessary. /Anabolic steroids/
Concurrent use /of glucocorticoid corticosteroids, especially with significant mineralocorticoid activity; mineralocorticoid corticosteroids; corticotropin, especially prolonged therapeutic use; or sodium-containing medications or foods/ with anabolic steroids may increase the possibility of edema; in addition, concurrent use of glucocorticoids or corticotropin with anabolic steroids may promote development of severe acne. /Anabolic steroids/
