Anastrozole, a non-steroidal aromatase inhibitor, is commonly prescribed for the treatment of hormone receptor-positive breast cancer in postmenopausal women. Its primary function is to lower estrogen levels in the body, which can help slow or stop the growth of certain types of breast tumors. Understanding the appropriate dosage is crucial for achieving the best therapeutic outcomes while minimizing side effects.
