    Description:

    Femara is a type of hormone therapy drug used to treat breast cancer in women who have had their menopause. It is also called Femara.
    Letrozol potently inhibits aromatase derived from a variety of different sources including human placental microsomes, particulate fractions of human breast cancer, rat ovarian microsomes, MCF-7 cells transfected with aromatase (MCF-7Ca), JEG-3 human choriocarcinoma cells , CHO cells and hamster ovarian tissue.

    Letrozol is in a class of medications called nonsteroidal aromatase inhibitors. It works by decreasing the amount of estrogen produced by the body. This can slow or stop the growth of some types of breast cancer cells that need estrogen to grow.

    What is Femara (Femara)?

    Be the first to review this Drug
    Femara, sold under the brand name Femara, is a prescription drug used to treat breast cancer in its advanced stages, and in women who have finished menopause.

    Doctors may use Femara off-label in fertility treatments to help encourage egg release (ovulation) in women.

    Femara belongs to a class of cancer drugs known as aromatase inhibitors, which work by preventing the body from converting a hormone called androgen into estrogen.

    This treatment has proven beneficial in cancers whose growth seems to be encouraged by excess estrogen in the body, like certain types of breast cancer.

    Originally manufactured by Novartis, the Food and Drug Administration (FDA) first approved Femara in 1997.

    Usage:

    Letrozol is used treat early breast cancer in women who have experienced menopause and who have had other treatments, such as radiation or surgery to remove the tumor. It is also used to treat early breast cancer in women who have experienced menopause and who have already been treated with a medication called tamoxifen (Nolvadex) for 5 years.

    Letrozol is also used in women who have experienced menopause as a first treatment of breast cancer that has spread within the breast or to other areas of the body or in women whose breast cancer has worsened while they were taking tamoxifen.
