    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.

     

    How Letrozole Works

     

    Letrozole lowers the levels of the female sex hormone oestrogen in the body. Oestrogen stimulates some breast cancers to grow. These breast cancers are called hormone sensitive or hormone receptor positive. Letrozole can stop or slow the growth of these cancers. It can also reduce the chance of a breast cancer coming back after surgery.

     

    Letrozole only works in women who have had their menopause. It is a type of drug called an aromatase inhibitor. After the menopause, women don’t produce oestrogen from their ovaries.

     

    But they still produce a small amount by using an enzyme called aromatase which turns other sex hormones called androgens into oestrogen. This change happens mainly in fatty tissue, muscle and the skin. Aromatase inhibitors block aromatase so that it can’t change the androgen into oestrogen.
