Description

Anastrozole is an aromatase inhibitor, an anti-cancer medication use for the adjuvant or initial treatment of breast cancer in post-menopausal women. Estrogen causes or increases growth of certain breast cancers. Anastrozole works by blocking aromatase enzyme, which is involved in estrogen production in the body. This leads to decreased tumor size or delayed progression of tumor growth in some women.

This medication is also used to treat breast cancer in women whose breast cancer has worsened after taking tamoxifen (Nolvadex). Anastrozole is in a class of medications called nonsteroidal aromatase inhibitors. It works by decreasing the amount of estrogen the body makes.

Anastrozole and tamoxifen: different paths to the same goal

First though, let’s look at how anastrozole works. The hormone oestrogen fuels the growth of many breast cancers. After women go through the menopause, their oestrogen is no longer produced by the ovaries’ instead it’s made by an enzyme called aromatase. Aromatase is found in fatty tissues (such as the breasts), muscle and the skin.
Anastrozole is a type of drug called an aromatase inhibitor. It blocks the action of aromatase and so lowers the amount of oestrogen in post-menopausal women. There are two other aromatase inhibitor drugs used to treat breast cancer, exemestane and letrozole. Exemestane has already shown promising results for preventing breast cancer and letrozole is also being investigated.
Tamoxifen is one of the most effective breast cancer treatments ever developed. It also works by blocking the action of oestrogen but does this in a different way. While anastrozole stops the production of the hormone, tamoxifen stops the oestrogen attaching to breast cancer cells. So oestrogen is still found in the body but its activity is blocked. This type of therapy is called selective oestrogen receptor modulators or SERMs.
