Medical Definition of Arimidex
Arimidex: Brand name for anastrozole, an oral antiestrogen. Arimidex inhibits the enzyme aromatase in the adrenal glands that produces the estrogens (estradiol and estrone) and thereby lowers their levels. It works by decreasing the amount of estrogen the body makes. This can slow or stop the growth of many types of breast cancer cells that need estrogen to grow.
