2 . Brief Introduction :

Formestane (Lentaron) is used for natural or artificial postmenopausal breast cancer patients, including tamoxifen and other endocrine treatment of patients is invalid

Formestane (Lentaron) is a type steroidal aromatase inhibitor. It is used in the treatment of estrogen-receptor positive breast cancer in postmenopausal 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.


3 . How it works :

Formestane 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. Formestane 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. Formestane, 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.
