Anastrozole

Anastrozole is a medication primarily used to treat breast cancer in postmenopausal women. It belongs to a class of drugs called aromatase inhibitors, which reduce estrogen levels in the body. Lowering estrogen helps slow the growth of certain types of breast cancer that depend on this hormone. Doctors commonly prescribe Anastrozole as part of hormone therapy, especially in early and advanced stages of hormone receptor-positive breast cancer.

Uses of Anastrozole

• Treatment of hormone receptor-positive breast cancer in postmenopausal women
• Prevention of breast cancer recurrence after initial treatment

How Anastrozole Works

Anastrozole inhibits the aromatase enzyme, which is responsible for converting androgens into estrogen. By reducing estrogen levels in the body, it slows or stops the growth of hormone receptor-positive breast cancer cells.
