What is Letrozole (Femara)?

Letrozole is a potent aromatase inhibitor that prevents the conversion of androgens into estrogen. Unlike Tamoxifen (a SERM that blocks estrogen receptors), Letrozole lowers overall estrogen levels, making it extremely effective in studies requiring strong estrogen suppression.
