1. What is Atrozol and What is it Used For

Anastrozole, the active substance of Atrozol, belongs to a group of medicines called aromatase inhibitors. Anastrozole is used for the treatment of breast cancer in post-menopausal women.

This happens as a result of the inhibition of the action of the substance (enzyme) called aromatase.
