It is a non-steroidal inhibitor of aromatase, an enzyme with the participation of which the synthesis of estrogen in women in the postmenopausal period occurs.
Aromatase promotes the conversion of androgens synthesized in the adrenal glands (primarily androstenedione and testosterone), in estrone and estradiol.
Inhibition of aromatase activity is realized by competitive binding to the subunit of this enzyme, the cytochrome P450 heme, which leads to a decrease in estrogen biosynthesis in all tissues, including in tissues of estrogen-dependent tumors.
Common breast cancer, mainly in postmenopausal women, including with resistance to antiestrogen therapy.
Hypersensitivity, premenopausal period, severe renal dysfunction (Cl creatinine <10 ml / min), pregnancy, breast-feeding (discontinue).
