Anastrozole

Anastrozole has significant effects on breast cancer treatment and, therefore, it is currently used as first-line treatment in estrogen receptor (ER)-positive postmenopausal women, particularly to treat locally advanced or metastatic breast cancer. Furthermore, it is also indicated for early cancer treatment, tumor chemoprevention and postmenopausal women using tamoxifen, especially if the drug is used during a prolonged period of time and has been indicated in the disease’s recurrence, i.e., as another therapeutic endocrine option.
