Anastrozole is a medication commonly used in the treatment of breast cancer, particularly in postmenopausal women. It works as an aromatase inhibitor, effectively lowering estrogen levels in the body, which can help slow the growth of certain types of breast tumors that rely on estrogen to grow. Understanding the appropriate dosage of Anastrozole is crucial for maximizing its efficacy while minimizing potential side effects.
