This medicine contains the active ingredient anastrozole which belongs to a group of medicines called aromatase inhibitors. It is a hormone treatment which decreases the amount of estrogen in the body which enables some breast cancers to grow. Anastrozole is used after the surgery, as well as for metastasis before the surgery. It is also sometimes used to prevent breast cancer in women who are at high risk of developing the disease.
