Pharmacology

Pharmacological action – antitumor, inhibitory synthesis of estrogens. It is active against estrogen-dependent breast tumors in postmenopausal women. Androstenedione – the main source of circulating estrogens in postmenopausal women, in peripheral tissues is converted to estrone, and then to estradiol, this process takes place with the participation of the aromatase enzyme. The mechanism of action of anastrozole is associated with the inhibition of aromatase (a selective non-steroidal inhibitor) in peripheral tissues, incl. Fatty, which leads to a decrease in the amount of estradiol. When anastrozole is treated at the recommended dose of 1 mg per day, the level of estradiol is reduced by 70% within 24 hours, by 80% after 14 days. Suppression of serum estradiol levels is maintained for 6 days after discontinuation of daily intake of 1 g of anastrozole. A decrease in the level of circulating estradiol has a therapeutic effect in breast tumors in postmenopausal women. With daily intake of doses of 3, 5 and 10 mg, anastrozole had no effect on the secretion of cortisol and aldosterone. Anastrozole did not show direct progestogen, androgenic and estrogenic activity in animals, but it altered the levels of circulating progesterone, androgens and estrogens.
