Description:

Lentaron was the first selective,type I,steroidal aromatase inhibitor used in the treatment of estrogen-receptor positive breast cancer in post-menopausal women. Formestane suppresses 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 acbagg as a mild aromatase inhibitor. It is listed as a prohibited substance by the World Anti-Doping Agency for use in athletes.
Lentaron has poor oral bioavailability,and thus must be administered forthnightly (bi-weekly) by intramuscular injection. Some clinical data has suggested that the clinically recommended dose of 250mg was too low. With the discovery of newer,non-steroidal and steroidal,aromatase inhibitors which were orally active and less expensive than formestane,formestane lost popularity.
Currently,Lentaron (categorized as an anti-estrogenic agent) is prohibited from use in sports in accordance to the regulations of the World Anti-Doping Agency. It is not US FDA approved,and the intramuscular injection form of Lentaron which was approved in Europe has been withdrawn.  
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.
Lentaron is often used to suppress estrogen production from anabolic steroids or prohormones. It also acts as a prohormone to 4-hydroxytestosteron,an active steroid which displays weak androgenic activity in addition to acbagg as a mild aromatase inhibitor.
Lentaron has poor oral bioavailability and as such is no longer popular as many orally active aromatase inhibitors have been identified.
Application:
Lentaron is a second generation,irreversible,steroidal aromatase inhibitor. It inhibits the aromatase enzyme responsible for converbagg androgens to estrogens,thereby prevenbagg 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.
