Anastrozole is used to treat breast cancer in women after menopause. Some breast cancers are made to grow faster by a natural hormone called estrogen. Anastrozole decreases the amount of estrogen the body makes and helps to slow or reverse the growth of these breast cancers.

The drug is appropriately used when using substantial amounts of aromatizing steroids, or when one is prone to gynecomastia and using moderate amounts of such steroids. Arimidex does not have the side effects of aminoglutethimide (Cytadren) and can achieve a high degree of estrogen blockade, much moreso than Cytadren. It is possible to reduce estrogen too much with Arimidex, and for this reason blood tests, or less preferably salivary tests, should be taken after the first week of use to determine if the dosing is correct.

What is anastrozole?

Anastrozole is a drug used to treat breast cancer in women who have gone through the menopause.

You may also hear it called Arimidex, which is its best-known brand name. There are a number of other brands of anastrozole, all of which contain the same dose of the drug.

Men with breast cancer may be given anastrozole, although another drug called tamoxifen is more commonly used.

How does anastrozole work?

Anastrozole works by reducing the amount of oestrogen made in the body.

Some breast cancers are stimulated to grow by the hormone oestrogen. These are known as oestrogen receptor positive or ER+ breast cancers.

Anastrozole belongs to a group of drugs called aromatase inhibitors.
