Formestane Structure

 

Description:

 

Formestane (Lentaron) is a type I, steroidal aromatase inhibitor. It 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.

Application:

Used for natural or artificial postmenopausal breast cancer patients, including tamoxifen and other endocrine treatment of patients is invalid. Used for breast cancer.


Used for natural or artificial postmenopausal breast cancer patients, including tamoxifen and other endocrine treatment of patients is invalid.

 

Formestane has a very long active life on the order of 24-36 hours. Formestane has zero negative feedback (even though it is an androgen by definition) and serves to elevate natural testosterone as well as any anti-estrogen/anti-aromatase drug out there, next to clomid.


Formestane attacks the aromatase enzyme and is therefore a first line inhibitor. So if you need immediate relief of estrogen during your cycle, you need a second class drug (estrogen receptor blocker) such as nolvadex or clomid. Formestane is a lot like arimidex in its mechanism of action in attacking the aromatase enzyme itself.
