Abstract

Formestane

 

Formestane is classified as a selective irreversible steroidal aromatase inhibitor. This agent is

 

structurally a derivative of androstenedione, differing from this well known prohormone only by the

 

addition of a 4-hydroxyl group. This group, however, is responsible for causing an irreversible

 

attachment between formestane and aromatase when the two come into contact with each other.

 

 

This means that formestane will bond with the enzyme and never let it go, permanently

 

deactivating it as a result. The enzyme will need to be replaced, through normal attrition, before

 

the body will recover its lost estrogen synthesizing capacity. This may take several days or more

 

following cessation of therapy. Given this mode of action, formestane is also referred to as a

 

"suicide" aromatase inhibitor, as the drug essentially sacrifices itself in the process of blocking

 

estrogen conversion. As a class of drugs, aromatase inhibitors are used (off-label) by male

 

bodybuilders and athletes to prevent the estrogenic side effects of certain anabolic/androgenic

 

steroids, and to increase fat loss and muscle definition while dieting.

 

 

Because of its potent estrogen-suppressing action, formestane has been used clinically to treat

 

breast cancer patients in a number of countries. It has been shown to be an effective option as a

 

second line of defense after tamoxifen, an estrogen receptor antagonist, has failed to elicit a

 

positive response with patients, and produces an overall response statistically similar to

 

tamoxifen when administered as the first-line therapy. In terms of overall potency, formestane is

 

not as strong as the selective third generation inhibitors like Arimidex (anastrozole) or Femara

 

(letrozole). One study, for example, notes a 79% level of suppression of estrogen levels with 4

 

weeks use of Arimidex 1 mg daily (on par with levels noted with Femara use), but only a 58%

 

level of suppression with intramuscular formestane injections (250 mg every two weeks). But next

 

to estrogen receptor antagonists like Clomid (clomiphene citrate) and Nolvadex (tamoxifen

 

citrate), formestane is significantly more effective at blocking the effects of estrogen in the body.

Applications

Formestane is used in the treatment of estrogen-receptor positive breast cancer in post-

 

menopausal women. It is available as an intramuscular depot injection.

Formestane is often used to suppress estrogen production from anabolic steroids or

 

prohormones. It also acts as a prohormone to 4-hydroxytestosterone, an active steroid which

 

displays weak androgenic activity in addition to acting as a mild aromatase inhibitor.

Formestane has poor oral bioavailability and as such is no longer popular as many orally

 

active aromatase inhibitors have been identified.

 

Dosage

The most common version of formestane sold was in a topical gel form and it was dosed at

 

100 - 200mgs per application. Users would apply it onto clean, dry skin and rub in thoroughly;

 

usually on the thighs or upper arms. It took 1 to 5 minutes to dry.

The injectable version for both breast cancer purposes and bodybuilders is 125mgs twice per

 

week or 250mgs once per week.
