Drug Indication

Arimidex is an aromatase inhibitor approved for adjuvant (post-surgery) treatment of hormone receptor-positive (HR+) early breast cancer and first-line or subsequent treatment of HR+ advanced or metastatic breast cancer in postmenopausal women.


General Info

The female hormone estrogen stimulates the growth of hormone receptor-positive breast cancer. Aromatase inhibitors block an enzyme that converts other hormones, known as androgens, into estrogen. They do not stop the ovaries from producing estrogen, so premenopausal women should only use them with other drugs that suppress ovarian function.

Studies show that aromatase inhibitors like Arimidex work better than tamoxifen for reducing the risk of recurrence after initial treatment of early breast cancer with surgery, radiation or chemotherapy. Arimidex was first approved in 1995.


Dosage

Dosing Info: Arimidex is taken as a once-daily tablet.


Side Effects
