Letrozole - Page 3

Since its FDA approval in 1997, Letrozole, marketed as Femara, has been a critical drug in treating breast cancer in postmenopausal women by reducing estrogen production. Athletes sometimes use this medication to avoid estrogen related issues such, as gynecomastia when taking  steroids as it works by blocking the aromatase enzyme that converts androgens to estrogens, in the body.
