Exemestane is an aromatase inhibitor primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. By decreasing estrogen levels in the body, exemestane helps to slow or stop the growth of certain types of breast tumors that require estrogen to grow. Proper dosing of exemestane is crucial for maximizing its effectiveness and minimizing potential side effects.
