Consumer Information
This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.
What the medication is used for
ANASTROZOLE is used for the treatment of postmenopausal women with hormone receptor positive breast cancer in the following conditions:
- adjuvant treatment for early breast cancer
- advanced breast cancer
What it does
In hormone sensitive breast cancer, estrogens fuel tumour growth. Following menopause, estrogens are still produced in small amounts in other tissues of the body such as the breasts, muscle and fat. These estrogens are produced when androgens (hormones produced by the adrenal glands) interact with aromatase, a naturally occurring enzyme in the body.
ANASTROZOLE belongs to a group of medicines called aromatase inhibitors and works by inhibiting the aromatase enzyme, thereby, suppressing the production of estrogens that can stimulate tumour growth. Suppressing the production of estrogens may help reduce the growth of breast cancer and delay the breast cancer from recurring.
Adjuvant means "in addition to." In early breast cancer, this means that additional treatment is required after primary treatment. The reason for this is that after surgery, a small number of cancer cells may remain in the body. These cells can continue to multiply and spread. Adjuvant therapy is given to prevent or delay these cells from multiplying and spreading. The purpose of adjuvant therapy with ANASTROZOLE is to help to delay the breast cancer from recurring. Cytotoxic chemotherapy, radiation, and hormonal treatment are three common forms of adjuvant treatment.
