The drug has the same international name and refers to antitumor agents. The drug is available in the form of pills. Its action is based on the properties of aromatase inhibitor - which is an inhibitor of the synthesis of estrogens. In the process of use, there is an anti-estrogenic effect. The processes of reducing aromatase activity are due to competitive binding to the prosthetic part of the cytochrome P450. In the postmenopausal period, estrogens are formed with the participation of the aromatase enzyme, which turns androgens, which are synthesized in the adrenal glands, passing into estradiol and estrone. Daily use of this drug leads to a marked decrease in the concentration of estrone, estradiol and estrone sulfate. The percentage reduction in concentration can reach 95% of the initial value. In the process of Letrozole exposure in patients, a decrease in the concentration of circulating estrogens and inhibition of synthesis in the tissues of breast tumors is observed. The result of the action is a regression of tumors and a reduction in relapse, as well as mortality.
Absorption occurs quickly and completely in the GI tract. When used, a violation of the synthesis of steroid hormones in the adrenal glands is not observed at all.
