Understanding the Anastrozole Mode of Action

Anastrozole is a medication commonly prescribed for the treatment of breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by blocking the enzyme responsible for converting androgens into estrogen. This inhibition of estrogen production is crucial in preventing the growth and spread of hormone-receptor-positive breast cancer cells.

How Does Anastrozole Work?

• Inhibits Aromatase: Anastrozole specifically targets the aromatase enzyme, which plays a key role in estrogen synthesis. By inhibiting this enzyme, anastrozole reduces the levels of circulating estrogen in the body.
• Reduces Estrogen Levels: Lowering estrogen levels is essential in the treatment of hormone-receptor-positive breast cancer, as these tumors rely on estrogen to grow and proliferate. By decreasing estrogen production, anastrozole helps slow down or stop cancer cell growth.
• Blocks Tumor Growth: The main mode of action of anastrozole is to block the growth-promoting effects of estrogen on breast cancer cells. This can help shrink tumors and prevent their recurrence.
