Arimidex (anastrozole) 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.
Arimidex is used to treat breast cancer in postmenopausal women.
Arimidex is often given to women whose cancer has progressed even after taking tamoxifen (Nolvadex, Soltamox).
