Exemestane is an oral steroidal aromatise inhibitor used in the adjuvant treatment of hormonally-responsive breast cancer in postmenopausal women. An aim in the treatment of hormone-receptor-positive patients in preventing recurrence is to lower estrogen levels that this breast cancer thrives on.
The main source of estrogen is the ovaries in premenopausal women, while in post-menopausal women most of the body's estrogen is produced in the adrenal gland from the conversion of androgens into estrogen by the aromatase enzyme. Exemestane tablets are an irreversible, steroidal aromatase inactivator, structurally related to the natural substrate androstenedione.
Exemestane is an irreversible selective aromatase inhibitor which acts as a false substrate for the aromatase enzyme, forming an intermediate that binds irreversibly to the active site causing its inactivation.
It also lowers circulating oestrogens in estrogen-dependent breast carcinoma.
