An aromatase inhibitor that works to prevent the final step of androgen synthesis, Anastrozole reduces oestrogen levels. As a result, tumours that grow through androgens are inhibited. This is why anastrozole is used in women after menopause with hormone-dependent tumours. It has no androgenic, estrogenic or gestagenic properties.
