Overview

Anastrozole is a non-steroidal aromatase inhibitor (AI), similar to letrozole, used to decrease circulating estrogen levels in the treatment of postmenopausal women with estrogen-responsive breast cancer. Anastrozole is also related to exemestane, a steroidal AI, but its non-steroidal nature provides stark advantages including a lack of steroid-associated adverse effects such as weight gain and acne. Aromatase inhibitors, including anastrozole, have become endocrine drugs of choice in the treatment of postmenopausal breast cancer due to a more favourable efficacy and adverse effect profile as compared to earlier estrogen receptor modulators such as tamoxifen. Anastrozole was first approved for use in the United States in 1995.

Background

Indication

Anastrozole is indicated as adjunct therapy in the treatment of hormone receptor-positive early breast cancer in postmenopausal women, and as a first-line treatment for hormone receptor-positive (or hormone receptor-unknown) locally advanced or metastatic breast cancer in postmenopausal women. It may also be used in the treatment of advanced breast cancer in postmenopausal women who experience disease progression despite treatment with tamoxifen.
