About Arimidex
Arimidex (generic name Anastrozole) is a first-line treatment of breast cancer in postmenopausal women. It slows the growth of advanced cancer within the breast and cancer that has spread to other parts of the body. Arimidex is also used to treat advanced breast cancer in postmenopausal women whose disease has spread to other parts of the body following treatment with tamoxifen (Nolvadex), another anticancer drug. Arimidex can also be prescribed along with other drugs to treat the early stages of breast cancer in postmenopausal women.
Arimidex combats the kind of breast cancer that thrives on estrogen. One of the hormones produced by the adrenal gland is converted to a form of estrogen by an enzyme called aromatase. Arimidex suppresses this enzyme and thereby reduces the level of estrogen circulating in the body.
Recommended dosage
ADULTS
The usual dose is a 1-milligram tablet taken once a day. If Arimidex is being used as an initial treatment for advanced breast cancer, you will continue taking the medication until it no longer works against the tumor. The optimal duration of therapy for early breast cancer has not been determined.
