1. What Letrozol Vir is and what it is used for
What Letrozol Vir is and how it works
Letrozol Vir contains the active ingredient letrozole. It belongs to a group of medications called aromatase inhibitors. It is a hormonal (or "endocrine") treatment for breast cancer. The growth of breast cancer is usually stimulated by estrogens, which are female sex hormones. Letrozol reduces the amount of estrogen by blocking an enzyme ("aromatase") involved in the production of estrogens, and thus can block the growth of breast cancers that need estrogens to grow. As a result, tumor cells grow more slowly or stop growing and/or spreading to other parts of the body.
What Letrozol Vir is used for
Letrozol is used to treat breast cancer in women who have gone through menopause, i.e., the cessation of menstrual periods.
Letrozol is used to prevent breast cancer from coming back. It can be used as the first treatment before breast cancer surgery, in case surgery is not immediately possible, or it can be used as the first treatment after breast cancer surgery or after five years of treatment with tamoxifen. Letrozol is also used to prevent the breast tumor from spreading to other parts of the body in patients with advanced breast cancer.
If you have any questions about how letrozol works or why you have been prescribed this medication, consult your doctor.
