Description

Celana Pharmacodynamics
Anastrozole is a highly selective nonsteroidal aromatase inhibitor. Aromatase is an enzyme by which, in postmenopausal women, androstenedione is converted in peripheral tissues to estrone and then to estradiol. Anastrozole has antitumor activity against estrogen-dependent breast tumors in postmenopausal women. In the postmenopausal period the drug in a daily dose of 1 mg causes decrease in concentration of estradiol by 80 %.
Anastrozole has no progestogenic, androgenic or estrogenic activity. Anastrozole in a daily dose up to 10 mg has no effect on cortisol and aldosterone secretion (therefore, no corticosteroid replacement therapy is required).

 

Indications
-Adjuvant therapy of early breast cancer, with positive hormone receptors in postmenopausal women, including, after adjuvant therapy with tamoxifen for 2-3 years.
-First-line therapy for locally advanced or metastatic breast cancer with positive or unknown hormone receptors in postmenopausal women.
-Second-line therapy for advanced advanced breast cancer after tamoxifen treatment in postmenopausal women.
