Aromatase inhibitors (AIs) are a class of medications primarily used in the treatment of hormone-sensitive breast cancer in postmenopausal women. They work by reducing estrogen levels in the body, which can help to slow or stop the growth of certain types of breast tumors. Proper dosage and administration of aromatase inhibitors are crucial for their efficacy and to minimize potential side effects.
