Description:

Formestanes is a second generation, irreversible, steroidal aromatase inhibitor. It inhibits the aromatase enzyme responsible for converting androgens to estrogens, thereby preventing estrogen production. Breast cancer may be estrogen sensitive or insensitive. A majority of breast cancers are estrogen sensitive. Estrogen sensitive breast cancer cells depend on estrogen for viability. Thus removal of estrogen from the body can be an effective treatment for hormone sensitive breast cancers. Formestanes has been targeted specifically for the treatment of postmenopausal women. Unlike premenopausal women who produce most estrogen in the ovaries, postmenopausal women produce most estrogen in peripheral tissues with the help of the aromatase enzyme. Formestanes, an aromatase inhibitor, can thus help to decrease the local production of estrogen by blocking the aromatase enzyme in peripheral tissues (ie. Adispose tissue of the breast) to treat hormone sensitive breast cancer.


Applications:
 
1.Treatment of Breast Cancer:
 
Because of its potent estrogen-suppressing action, formestanes has been used clinically to treat breast cancer patients in a number of countries including England, Germany, Switzerland, Spain, Australia, New Zealand, Italy, and Malaysia. It has been shown to be an effective option as a second line of defense after, an estrogen receptor antagonist, has failed to elicit a positive response with patients, and produces an overall response statistically similar to when administered as the first-line therapy. In terms of overall potency, formestanes is not as strong as the selective third generation inhibitors like Arimidex () or Femara .
 
2.Use for Bodybuilding:
 
Formestanes can lower SHBG up to 34%, which will increase free levels. SHBG (sex hormone binding globulin) is a protein that binds to sex steroids, and renders them inactive, for as long as SHBG is bound to them. There is a difference between 'free' , and 'bound' .
