About
Anastrozole, marketed as Aromita, is a highly potent and selective non-steroidal aromatase inhibitor. Its mechanism of action involves reversibly binding to the aromatase enzyme, which is a key enzyme responsible for the conversion of adrenal androgens into estrogens in peripheral tissues, particularly in postmenopausal women. By effectively blocking this enzymatic pathway, anastrozole significantly reduces the circulating levels of estrogen. This reduction is critical in the management of hormone-receptor-positive breast cancer, as estrogen acts as a growth factor for these cancer cells. By depriving these cells of estrogen, anastrozole helps to inhibit tumor growth and progression. It is widely used as an adjuvant therapy for early breast cancer and as a treatment for advanced breast cancer in postmenopausal women, offering a targeted endocrine approach to cancer management.
