Anastrozole is a medication commonly used in the treatment of hormone-receptor-positive breast cancer in postmenopausal women. It works by inhibiting the aromatase enzyme, which is responsible for the production of estrogen in the body. Proper dosing is essential to ensure the effectiveness of the treatment while minimizing potential side effects.
