Description
A highly selective non-steroidal aromatase inhibitor. Aromatase is an enzyme that converts androstenedione in peripheral tissues in postmenopausal women into estrone and further into estradiol. Reducing circulating estradiol levels has a therapeutic effect in breast cancer patients. In postmenopause the drug in a daily dose of 1 mg causes reduction of estradiol level by 80%.
Arimidex has no progestagenic, androgenic and estrogenic activity.
Arimidex in a daily dose of up to 10 mg has no effect on cortisol and aldosterone secretion (therefore, the drug does not require replacement administration of corticosteroids).
