Understanding Aromatase Inhibitors Dosage
Aromatase inhibitors (AIs) are critical medications used primarily in the treatment of hormone receptor-positive breast cancer in postmenopausal women. These drugs work by blocking aromatase, an enzyme responsible for converting androgens into estrogens, thereby reducing estrogen levels in the body. By decreasing estrogen concentration, AIs help slow or stop the growth of hormone-sensitive tumors.
