Description
Exemestane, marketed as Aromasin, is an oral medication that belongs to a class of drugs known as aromatase inhibitors. It is used primarily to treat breast cancer in postmenopausal women, particularly those who have experienced a recurrence or progression of the disease following tamoxifen therapy. As an aromatase inhibitor, exemestane works by reducing estrogen production in the body, which is important because certain types of breast cancer grow under the influence of estrogen.
