Anastrozole: What Is It?

Anastrozole is a medication widely used in the treatment of breast cancer, particularly in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which play a crucial role in reducing estrogen levels in the body.

How Anastrozole Works

The primary mechanism of anastrozole involves inhibiting the aromatase enzyme, responsible for converting androgens into estrogens. By lowering estrogen production, this drug effectively slows or stops the growth of certain types of breast tumors that require estrogen to grow.

Indications for Use

• Postmenopausal women with hormone receptor-positive breast cancer.
• Adjuvant treatment following surgery to reduce the risk of cancer recurrence.
• As a first-line treatment option for advanced breast cancer.
