Arimidex (anastrozole)-1 mg aromatase inhibitor

Description:

Anastrozole, sold under the brand name Arimidex among others, is an antiestrogenic medication used in addition to other treatments for breast cancer. Specifically it is used for hormone receptor-positive breast cancer. It has also been used to prevent breast cancer in those at high risk. It is taken by mouth.

Working:

Arimidex works by blocking the enzyme aromatase, which turns the hormone androgen into small amounts of estrogen in the body. This means less estrogen is available to stimulate the growth or hormone receptor-positive breast cancer cells. Arimidex will not work on hormone receptor-negative breast cancer.

Dosage for Arimidex：

The dose of Arimidex is one 1 mg tablet taken once a day. For patients with advanced breast cancer, the medication should be continued until tumor progression.
