Exemestane 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.
Exemestane is used to treat breast cancer in postmenopausal women. It is often given to women whose cancer has progressed even after surgery, radiation, or other cancer medications have been tried without success.
Exemestane may also be used for purposes not listed in this medication guide.
Exemestane is part of a general group of drugs called aromatase inhibitors. Normally in the body, some of the androgens (male hormones) that are made by the adrenal glands are converted to estrogen by an enzyme in fat tissue called aromatase. This drug blocks aromatase so that estrogen isn’t formed that way. This lowers estrogen levels in women who do not have functioning ovaries. This drug doesn’t affect estrogen production from the ovaries, so has little effect on estrogen levels in women whose ovaries are working. If estrogen levels are lowered, breast cancers that require estrogen to grow may stop growing or even shrink.
