Adnast 1mg Tablet

About

Anastrozole is a potent and highly selective non-steroidal aromatase inhibitor, primarily used in the treatment of hormone-receptor-positive breast cancer in postmenopausal women. Its mechanism of action involves blocking the enzyme aromatase, which is responsible for the peripheral conversion of androgens into estrogens. By significantly reducing circulating estrogen levels, anastrozole effectively deprives estrogen-dependent breast cancer cells of the growth stimulus they require, thereby inhibiting tumor proliferation. This targeted therapy is a cornerstone in adjuvant treatment for early breast cancer and for advanced or metastatic disease, offering a crucial option for managing estrogen-sensitive tumors. Its efficacy in improving disease-free survival and reducing recurrence rates, coupled with its oral administration, makes it a valuable agent in oncology, though potential side effects like arthralgia and bone density loss require monitoring.

Uses

• Adjuvant treatment of early hormone receptor-positive breast cancer in postmenopausal women.
