4 Drug and Medication Information
4.1 Therapeutic Uses

Anabolic Steroids

National Library of Medicine's Medical Subject Headings online file (MeSH, 1999)


/Ethylestrenol/ has been used in for the promotion of growth in boys with short stature or delayed bone growth.

Reynolds, J.E.F., Prasad, A.B. (eds.) Martindale-The Extra Pharmacopoeia. 28th ed. London: The Pharmaceutical Press, 1982., p. 1554


4.2 Drug Warning

Use of anabolic steroids by athletes is not recommended. Objective evidence is conflicting and inconclusive as to whether these medications significantly increase athletic performance by increasing muscle strength. Weight gains reported by athletes are due in part to fluid retention, which is a potentially hazardous side effect of anabolic steroid therapy. The risk of other unwanted effects, such as testicular atrophy and suppression of spermatogenesis in males; menstrual disturbances and virilization, such as deepening of voice, development of acne, and unnatural growth of body hair in females; peliosis hepatis or other hepatotoxicity; and hepatic cancer outweigh any possible benefit received from anabolic steroids and make their use in athletes inappropriate. /Anabolic Steroids/

5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Anabolic Agents

These compounds stimulate anabolism and inhibit catabolism. They stimulate the development of muscle mass, strength, and power. (See all compounds classified as Anabolic Agents.)


5.2 ATC Code

A - Alimentary tract and metabolism

A14 - Anabolic agents for systemic use

A14A - Anabolic steroids

A14AB - Estren derivatives

A14AB02 - Ethylestrenol


5.3 Absorption, Distribution and Excretion

The absorption, distribution, metabolism and excretion of [3H]ethylestrenol were studied in the rat. 2. Approximately one third of an intragastric dose was absorbed; 17% of the dose was excreted in urine and 83% in faeces within 10 days. 3. The dose is distributed throughout the rat, and kidney and liver were found to contain respectively 2.5-3 and 5-7 times the average specific activity of all other tissues. 4. Unchanged ethylestrenol was the only component detected in urine. Ethylestrenol was also found in faeces, along with two different dihydroxylated dihydro derivatives and one trihydroxylated dihydro derivative.

PMID:7233967 Stelle JW et al; Xenobiotica 11(2):103-15 (1981)


It is not known whether anabolic steroids are distributed into breast milk. /Anabolic Steroids/

5.4 Metabolism/Metabolites

Ethylestrenol incubated with a post-mitochondrial supernatant fraction of rat liver plus co-factors gives norethandrolone as the major metabolite. A second (minor) metabolite was tentatively identified as 17 alpha-ethyl-5 epsilon-estrane-3 epsilon,17 beta-diol. A pathway is suggested for the metabolism of ethylestrenol in the rat.

PMID:7233968 Steele JW et al; Xenobiotica. 1981 Feb;11(2):117-21.


Orabolin was oxidized at C-3 to form nilevar which in turn was metabolized in man by a ring reduction and side chain hydroxylation to form a 19-norpregnatriol. Identification of this metabolite, detection in urine is test for athletes suspected of drug misuse.

PMID:410996 Ward et al; J Steroid Biochem 8 (10): 1057-63 (1977)


5.5 Mechanism of Action

Anabolic steroids reverses catabolic processes and negative nitrogen balance by promoting protein anabolism and stimulating appetite if there is concurrently a proper intake of calories and proteins. /Anabolic Steroids/
