What is Arimidex 

Arimidex 1 mg, containing Anastrozole, is used to treat early breast cancer in postmenopausal women. 

It is used for the first-line treatment of Metastatic (cancer that has spread) Breast Cancer in postmenopausal women.

Arimidex uses

It is prescribed alone or with other treatments to treat early Breast Cancer in postmenopausal women.

Breast Cancer 

Breast Cancer is a disease in which cells in the breast grow out of control. 

It happens in different forms. Which type of Breast Cancer you have depends on which cells in your breast become cancerous.

Being a woman and becoming older are the primary factors that increase the risk of Breast Cancer. 

The majority of Breast Cancers occur in women aged 50 or older.

Amiridex effectively treats the symptoms of early Breast Cancer in postmenopausal women. 

How Arimidex works 

Arimidex contains Anastrozole, which belongs to a class of medications called Nonsteroidal Aromatase Inhibitors.

Many Breast Cancers are made to grow faster by a natural hormone called Estrogen. 

This medication reduces the body's production of Estrogen to which the Breast cancer tumor is exposed.

As a result, it slows down or reverses the growth of these Breast Cancers.
