Anastrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by lowering estrogen levels in the body, thereby slowing or stopping the growth of certain types of breast tumors that rely on estrogen. Proper dosing is crucial for the effectiveness of this medication.
