Anastrozole is in a class of medications called nonsteroidal aromatase inhibitors. 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.
Anastrozole is used to treat early hormone receptor-positive breast cancer. It is also used for first-line treatment of hormone receptor-positive or hormone receptor-unknown advanced or metastatic (cancer that has spread) breast cancer.
Anastrozole structure and mechanism of action. Anastrozole is a nonsteroidal AI that inhibits the aromatase enzyme by binding reversibly to its heme ion. By inhibiting the activity of aromatase, anastrozole reduces the levels of E2, E1, and E1S both in the periphery and in the mammary tissue.
