Letrozole(Femara) Description
Femara is a powerful Aromatase Inhibitor that was developed to fight breast cancer. For athletes and bodybuilders, it is a drug used to combat the estrogenic side effects of anabolic steroids water-retention, acne and gynocomastia. It will also raise testosterone levels because of the lowered estrogen in the body. Side effects from include a lowered sex drive and continuous use can lead to lowered lipid function and an impaired immune system. Femara is intended for use only by women who are no longer of childbearing age. Possible candidates must have already ceased to menstruate. It is often used in patients who have already undergone other cancer treatments, such as radiation, chemotherapy, and used other cancer drugs, like tamoxifen. This nonsteroidal aromatase inhibitor may help prevent any remaining cancer cells from spreading. Femara is used for the treatment of post-menopause breast cancer. Letrozole Femara is approved by the United States Food and Drug Administration (FDA) for the treatment of local or metastatic breast cancer that is hormone receptor positive or has an unknown receptor status in postmenopausal women.

Clinically it is used to treat postmenopausal women with either estrogen receptor positive or estrogen receptor unknown breast cancer. In women with breast cancer, it has been shown to reduce estrogen levels by 98% or more (1). However, it’s use and benefits are not limited to eliminating estrogen in women. For pre-contest bodybuilders, Letrozole is almost a necessity to eliminate water retention and achieve the ripped look necessary to compete in today’s bodybuilding world. However, in my experience, it is only necessary to be used for the last 4-6 weeks, to eliminate excess estrogen and water retention. After using Letrozole I recommend staying away from any estrogen suppression for at least a month to try to normalize the body.Letrozole(Femara) Effect

Femara is a new drug developed for the treatment of advanced breast cancer in women. Femara is the second in a new class of third-generation selective oral aromatase inhibitors. It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen. Since many forms of breast cancer cells are stimulated by estrogen, it is hoped that by reducing amounts of estrogen in the body the progression of such a disease can be halted. This is the basic premise behind Nolvadex, except this drug blocks the action and not production of estrogen. The effects of Femara can be quite dramatic to say the least. A daily dose of one tablet (2.5 mg) can produce estrogen suppression greater than 80 % in treated patients. With the powerful effect this drug has on hormone levels, it is only to be used (clinically) by post-menopausal women whose disease has progressed following treatment with Nolvadex. Side effects like hot flushes and hair thinning can be present, and would no doubt be much more severe in pre-menopausal patients. Femara is approved by the United States Food and Drug Administration (FDA) for the treatment of local or metastatic breast cancer that is hormone receptor positive or has an unknown receptor status in postmenopausal women.Femara is intended for use only by women who are no longer of childbearing age.

Letrozoles lowers estrogen levels in postmenopausal women, which may slow the growth of certain types of breast tumors that need estrogen to grow in the body. Letrozoles is an aromatase inhibitor. It works by reducing the total amount of estrogen produced primarily in the body. This helps to starve cancer cells by depriving them of estrogen. Letrozoles is used to treat breast cancer (such as hormone-receptor-positive breast cancer) in postmenopausal women. It is often given to women who have been taking tamoxifen (Nolvadex, Soltamox) for 5 years. Primarily treating certain kinds of breast cancer in women past menopause. It may also be used for other conditions as determined by your doctor. Letrozoles is also used to help prevent the cancer from returning. Some breast cancers are made to grow faster by a natural hormone called estrogen. Letrozoles decreases the amount of estrogen the body makes and helps to slow or reverse the growth of these breast cancers. This medication may also be used to treat infertility in women.Letrozole(Femara) Specifications
