Aromatase Inhibitor

Aromatase Inhibitor (AI) is a type of drug used to inhibit the activity of the enzyme aromatase. Aromatase is an enzyme involved in the synthesis of estrogen, and AI medications are used to block the production of estrogen in the body. AI medications are commonly used to treat breast cancer in post-menopausal women as they are able to reduce the amount of estrogen in the body and stop the estrogen from stimulating the growth of breast cancer cells. AI medications can also be used in the treatment of endometriosis, fibroids and to help with fertility in women. AI medications can also be used to reduce the amount of testosterone in men with prostate cancer, and can be used in the treatment of male-pattern baldness.
