How Does Arimidex Work?
Arimidex® (anastrozole) is a medication used to treat breast cancer in postmenopausal women. It belongs to a class of drugs called aromatase inhibitors. But how does Arimidex work?
In postmenopausal women, most of the estrogen in the body is made by aromatase. Many breast cancers are sensitive to the estrogen hormone, meaning that the tumor grows with the help of estrogen. When a tumor is sensitive to estrogen, it has receptors on the outer surface of its cells. Estrogen fits into these receptors like a key opening a lock. When this connection is made, the cancer grows.
Arimidex works by blocking aromatase enzymes, which decreases the amount of estrogen produced in the body. By decreasing estrogen production, Arimidex helps to slow down the growth of certain breast cancers. This type of treatment for breast cancer is known as hormonal therapy.
