Letrozole 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.

Applications

 

Letrozole 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.In fact,it would prove to be virtually identical to the already popular AI in Arimidex .Letrozole 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.

It will also raise testosterone levels because of the lowered estrogen in the body.

 


Dosage for Anabolic Steroid Use


The general range of Letrozole doses are approximately 1.25mg – 2.5mg daily. There does exist a very large margin for adjustment and user preference when it comes to Letrozole dosages, as each individual should slowly adjust their dose depending on how they feel the body is responding. This is especially so for Letrozole, which is the most powerful and potent AI of the three. Even 1.25mg daily is too much for many anabolic steroid users, and often times the recommended dose is actually 1.25mg every other day, and often can be even less frequent especially considering the half-life of Letrozole is that of 2 – 4 days. These Letrozole doses can easily be adjusted if the user feels it is not working well enough, or if it is reducing Estrogen levels too much.

Functions

 

Letrozole holds the purpose of blocking the aromatase enzyme, which is in turn responsible for the production of estrogen.

It 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.
