Formestane Descrption


Formestane was developed for use in treatment of estrogen-receptor-positive breast cancer in post-menopausal women. For medical purposes, it is made in intramuscular depot form and injected. It is not used in oral form due to poor bioavailability, which makes the oral version inferior to aromasin, , and arimidex.


Formestane 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.


Formestane Application


Formestane Is the second generation of irreversible steroid aromatase inhibitors. It inhibits the aromatase responsible for converting androgen into estrogen, thereby preventing estrogen production. 


Formestane 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 acting as a mild aromatase inhibitor.


Formestane is dedicated to the treatment of postmenopausal women. Unlike premenopausal women who produce the most estrogen in the ovaries, postmenopausal women produce most estrogens in peripheral tissues with the help of aromatases. 


Formestane is more selective than amino isoflavones, and its activity is amino-hydroxyethylamine 100 to 1000 times, does not inhibit the synthesis of adrenal hormones, without the need to add cortisone and so on. The in vitro inhibition of the product's aromatase is 60 times stronger than that of aminosuccinimide.


When Formestane is used alone, when it is combined with goserelin (gonadotropin-releasing hormone agonist), the drug does not significantly reduce premenopausal estrogen levels in women's blood, and estrogen inhibition in premenopausal women The effect is greater than that of goserelin alone using methanesulfonic acid with other aromatase inhibitors without cross resistance, which does not have side effects of aminoglucan.


Formestane Dosage


Formestane has a very long active life on the order of 24-36 hours. Lentaron is available as an intramuscular depot injection, and is often found in 2 ml ampules of 125 mg/ml solution. The recommended dosage for bodybuilder purposes is the same as that for advanced breast cancer therapy, namely 250 mg per week. Formestane can also be found, and taken in the same 250 mg per week dosage in its oral form, but the oral had poor bioavailability is no longer a popular version of this drug.
