2.Description:

 

Exemestane is a steroidal Aromatase Inhibitor (AI) that is most commonly known as Aromasin. In fact, the Aromasin brand name is the only pharmaceutical grade brand of the Exemestane AI due to the tight patent Upjohn has maintained on the product. While tightly controlled by the pharmaceutical giant, Aromasin is available in numerous countries around the globe.

Aromasin was first released on the U.S. market in 2000 after shortly gaining FDA approval a few months prior in 1999. The primary purpose of use as with most AI's would be to combat breast cancer in post-menopausal women. Shortly after, the AI would begin to gain a lot of popularity among anabolic steroid users for its ability to protect against estrogenic related side effects. This action is very similar to the older and more popular AI's in Arimidex and Femara It would also gain a fair amount of popularity in Post Cycle Therapy (PCT) plans among steroid users. It was not the first AI to gain such popularity but would prove to be a little more advantageous for this purpose than most AI's

Aromasin is officially classified as a steroidal suicide Aromatase Inhibitor, and carries the ability to inhibit the aromatase enzyme, which is responsible for the production or conversion of testosterone to estrogen. Aromasin has the ability to block aromatization, which in turn inhibits the production of estrogen, and thereby lowers the body's serum estrogen levels. This will prove useful to breast cancer patients as breast cancer often feeds off the estrogen hormone. It will also prove useful to the anabolic steroid user.

 


3.Applications :

 

The third generation aromatase inhibitors, used in the treatment of metastatic breast cancer and used as aid in the treatment of early breast cancer.

Many breast cancers are stimulated to grow by the female sex hormones oestrogen and progesterone. These breast cancers are called hormone sensitive or hormone receptor positive and can be treated with drugs that block the effects of these hormones.

In women who have had their menopause, oestrogen is mainly produced by changing androgens (sex hormones produced by the adrenal glands) into oestrogens. This process is called aromatisation and happens mainly in the fatty tissues, muscle and the skin. It needs a particular enzyme called aromatase. Exemestan blocks the process of aromatisation. So it lowers the amount of oestrogen in the body. In early breast cancer, taking exemestane can help to stop breast cancer coming back. In advanced breast cancer the cancer cells may grow more slowly or stop growing completely.

Hormones are chemical substances that are produced by glands in the body, which enter the bloodstream and cause effects in other tissues. For example, the hormone testosterone made in the testicles and is responsible for male characteristics such as deepening voice and increased body hair. The use of hormone therapy to treat cancer is based on the observation that receptors for specific hormones that are needed for cell growth are on the surface of some tumor cells. Hormone therapies work by stopping the production of a certain hormone, blocking hormone receptors, or substituting chemically similar agents for the active hormone, which cannot be used by the tumor cell. The different types of hormone therapies are categorized by their function and/or the type of hormone that is affected.

Exemestan is an aromatase inhibitor. This means it blocks the enzyme aromatase (found in the body's muscle, skin, breast and fat), which is used to convert androgens (hormones produced by the adrenal glands) into estrogen. In the absence of estrogen, tumors dependent on this hormone for growth will shrink.

5.How it works:

 

Some breast cancers are stimulated to grow by the hormone oestrogen. In women who have been through the menopause, oestrogen is no longer produced by the ovaries. But some oestrogen is still made in body fat using an enzyme (a type of protein) called aromatase. Aromatase inhibitors stop this enzyme from working so there’s less oestrogen in the body.

Exemestane will only be prescribed if your breast cancer has receptors within the cell that bind to the hormone oestrogen, known as oestrogen receptor positive or ER+ breast cancer. All breast cancers are tested for oestrogen receptors using tissue from a biopsy or after surgery. When oestrogen binds to these receptors, it can stimulate the cancer to grow.

When oestrogen receptors are not found (oestrogen receptor negative or ER- breast cancer) tests may be done for progesterone (another hormone) receptors. The benefits of hormone therapy are less clear for people whose breast cancer is only progesterone receptor positive (PR+ and ER-). Very few breast cancers fall into this category. However, if this is the case for you your specialist will discuss with you whether exemestane is appropriate.

If your cancer is hormone receptor negative, then exemestane will not be of any benefit.

 


6.Usage:

 

This medication is used to treat certain types of breast cancer (such as hormone-receptor-positive breast cancer) in women after menopause. Exemestane is also used to help prevent the cancer from returning. Some breast cancers are made to grow faster by a natural hormone called estrogen. Exemestane decreases the amount of estrogen the body makes and helps to slow or reverse the growth of these breast cancers.

Exemestane is usually not used in women of childbearing age.

 


7.Dosage:

In a study, Aromasin dosed at 25mg per day increased total testoste by 60% in only 10 days. Even better than that, is the fact that free (useable) testoster increased over 100% in the same time frame! In addition, Aromasin also increases IGF-1 levels. There is no estrogen rebound from Aromasin, and it is also a very powerful and effective treatment for gynecomastia. All of this makes Aromasin a no-brainer for post cycle therapy as well as on cycle estrogen control.
