Contents of the package leaflet
What is Letrozol TecniGen and how does it work
Letrozol TecniGen contains an active substance called letrozole. It belongs to a group of medicines 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 TecniGen reduces the amount of estrogen by blocking an enzyme ("aromatase") involved in estrogen production and can therefore 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 TecniGen is used for
Letrozol TecniGen is used to treat breast cancer in women who have passed the menopause, i.e., the cessation of menstrual periods.
It is used to prevent breast cancer from coming back. It can be used as the first treatment before breast cancer surgery, if 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 TecniGen is also used to prevent the breast tumor from spreading to other parts of the body in patients with advanced breast cancer.
