Summary of Clinical Use
Approved for the treatment of local or metastatic breast cancer that is hormone receptor positive or has an unknown receptor status in postmenopausal women.
Mechanism Of Action and Pharmacodynamic Effects
Aromatase (CYP19A1) inhibitors suppress the aromatization of androgens into estrogens. In postmenopausal women this action can have an anti-proliferative effect on the growth of estrogen-responsive cancers.
