How does Arimidex® work?
Arimidex belongs to a group of medicines called aromatase inhibitors.

This means that it interferes with some of the actions of aromatase, an enzyme (chemical that controls other chemical reactions), which is involved in the production of oestrogens within the body.
Oestrogens are female sex hormones that are known to be able to encourage the growth of some types of breast cancer cells.

Aromatase is the main enzyme responsible for the production of oestrogens in postmenopausal women.

By preventing the production of oestrogens, Arimidex prevents the hormones from promoting the growth of breast cancers.
