A hormonal therapy used to treat breast cancer in postmenopausal women whose cancers have not responded well to tamoxifen (Nolvadex). Aromasin interferes with the production of estrogen so that the growth of breast cancers that require estrogen may slow.

Brand name, Aromasin. Drug used to treat metastatic breast cancer in post-menopausal women. Works by binding to the body’s aromastase enzyme, an enzyme responsible for producing the hormone, estrogen.

Exemestane belongs to a class of drugs called aromatase inhibitors. Aromatase inhibitors prevent the conversion of androgens to estrogen, which is the primary source of estrogen production in postmenopausal women. Estrogen plays a key role in the development and growth of most types of breast cancer and inhibition of estrogen may prevent breast cancer in many women. Exemestane is FDA and Health Canada approved, is marketed as AROMASIN(tm) and manufactured by Pfizer, Inc. It is currently used for the treatment of advanced breast cancer in postmenopausal women whose disease has progressed following tamoxifen therapy.
