Description:

 

Letrozole is an oral non-steroidal inhibitor for the treatment of hormonally-responsive breast cancer after surgery.
Letrozole prevents the aromatase from producing estrogens by competitive, reversible binding to the heme of its cytochrome p450 unit, the action is specific,and letrozol does not reduce production of mineralo-or corticosteroids.

Letrozole lowers estrogen levels in postmenopausal women, which may slow the growth of certain types of breast tumors that need estrogen to grow in the body.

Letrozole is used to treat breast cancer in postmenopausal women. It is often given to women who have been taking tamoxifen (Nolvadex, Soltamox) for 5 years.
