Femara, sold under the brand name Femara, is a prescription drug used to treat breast cancer in its advanced stages, and in women who have finished menopause. Doctors may use Femara off-label in fertility treatments to help encourage egg release (ovulation) in women. Femara belongs to a class of cancer drugs known as aromatase inhibitors, which work by preventing the body from converting a hormone called androgen into estrogen.
L Etrozole is a type II (non-steroidal) third generation aromatase inhibitor. Clinically it is used to treat postmenopausal women with either estrogen receptor positive or estrogen receptor unknown breast cancer.
For pre-contest bodybuilders, L Etrozole is almost a necessity to eliminate water retention and achieve the ripped look necessary to compete in today's bodbuilding world.
