Product Description:
 
 

1. Letrozole is an anti-Estrogen of the Aromatase Inhibitor (AI) family and is one of the most potent and powerfully effective of all AI’s. In fact, its potency is sometimes too much for some to handle when used for off label use. Letrozole first gained U.S. FDA approval in 1997 and would hit the market under the brand name Femara through Novartis.

2. Although Femara is the dominating trade name of the AI, unlike most AI’s it is the only one generally known by its chemical name Letrozole far more commonly than its dominating brand name.

3. Letrozole was first developed in an effort to combat breast cancer in post-menopausal women. In fact, it would prove to be virtually identical to the already popular AI in Arimidex (Anastrozole). While intended for breast cancer treatment, like many AI’s, it has found a welcomed home among anabolic steroid users.

4. Letrozole is one of the most commonly used anti-estrogens among steroid users during steroid use to combat possible estrogenic related side effects. It is so effective as an anti-estrogen in this regard many anabolic steroids have effectively reversed gynecomastia symptoms with Letrozole.

 

 

Letrozole Functions :

1. Letrozole is an AI, which holds the purpose of blocking the aromatase enzyme, which is in turn responsible for the production of estrogen. By inhibiting estrogen production, this lowers total serum estrogen levels in the body.

2. This will be useful to the breast cancer patient on the basis of such cancer often feeding off the estrogen hormone. It will be beneficial to the anabolic steroid user as excess estrogen often leads to some of the most commonly associated side effects of anabolic steroid use.

3. Letrozole also carries the ability to increase natural estrogeneproduction through an increase in Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH). There have been physicians who have chosen Letro as it’s often known to treat low testosterone conditions, but this is normally not the preferred method of treatment.

4. Without question, when it comes to low testosterone treatment exogenous testosterone is generally the only thing that makes sense. However, Letrozole can be useful in such a plan in conjunction with exogenous testosterone in order to combat possible side effects. We will look into this in the effects section.

 
Application:
 
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. 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. 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.
 
 
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.
