1. The second generation aromatase inhibitors are used to treat metastatic breast cancer and as adjuvant therapy for early breast cancer.

2. Exemestane is the first oral hormonal drug. It selectively targets and permanently binds to aromatase. Once it binds to the enzyme, the enzyme can never produce estrogen again. It inhibits the supply of estrogen to cancer cells and helps prevent cell growth. It is used in the treatment of metastatic breast cancer and as an early stage agent. Adjuvant treatment of breast cancer.

3. This product is the second generation aromatase inhibitor. It can irreversibly combine with aromatase to inactivate it, thus preventing the biosynthesis of estrogen. It is clinically used to treat metastatic breast cancer and as an adjuvant therapy for early breast cancer. It has definite efficacy, good tolerance and relatively few side effects.


Pharmacological action:

The growth of breast cancer cells depends on the presence of estrogen. Estrogen (estrone and estradiol) in the postmenopausal cycle of women is mainly converted from androgen (androgen and testosterone) in the adrenal gland and ovary by aromatase in peripheral tissues. Inhibiting estrogen production by inhibiting aromatase is an effective and selective treatment for postmenopausal hormone-dependent breast cancer. Exemestane is an irreversible steroidal aromatase inactivator, similar in structure to androstenedione, the natural substrate of the enzyme. It is a pseudo-substrate of aromatase. It can be inactivated by irreversibly binding to the active site of the enzyme (also known as "self-destructive inhibition"), thus significantly reducing the female circulation in menopausal women. Hormone levels had no significant effect on the biosynthesis of corticosteroids and aldosterol in the adrenal gland. When the concentration of aromatase was 600 times higher than that of aromatase, it had no significant effect on other enzymes in steroid production pathway.



It is suitable for patients with advanced postmenopausal breast cancer who progress after tamoxifen treatment
