How does Arimidex work?
Anastrozole, the generic version of Arimidex, is a non-steroidal aromatase inhibitor that works in the body by stopping an enzyme called aromatase. In post-menopausal women, the sex hormones androstenedione and testosterone are converted into oestrogen due to the effect of this enzyme. Many breast cancer types are boosted by the presence of oestrogen. By inhibiting the action of aromatase, Anastrozole stops oestrogen production and thereby arrests the growth of the cancer, making treatment easier.
