Anastrozole is a medication that belongs to a class of drugs known as aromatase inhibitors. It is primarily used in the treatment of breast cancer, particularly in postmenopausal women. By inhibiting the aromatase enzyme, Anastrozole reduces the production of estrogen in the body, which can help slow or stop the growth of certain types of breast tumors that require estrogen to grow.
