Final answer:
Anastrozole, Letrozole, and Exemestane are all drugs that belong to the class of aromatase inhibitors and are used in the treatment of hormone receptor-positive breast cancer in postmenopausal women.
Step-by-step explanation:
Anastrozole, Letrozole, and Exemestane are all drugs that belong to a class called aromatase inhibitors. These drugs are commonly used in the treatment of hormone receptor-positive breast cancer in women who have gone through menopause.
Anastrozole (brand name Arimidex), Letrozole (brand name Femara), and Exemestane (brand name Aromasin) work by blocking the enzyme aromatase, which is responsible for converting certain hormones into estrogen in postmenopausal women. By reducing estrogen levels, these drugs help slow down the growth of breast cancer cells that rely on estrogen to grow.
It's important to note that these drugs should only be used under the supervision of a healthcare provider, as they may have side effects and interactions with other medications.
