Anti Estrogen Steroids CAS 120511-73-1 Anastrozole Powder

Anastrozole (INN) (marketed under the trade name Arimidex by AstraZeneca) is a non-steroidal aromatase-inhibiting

drug approved for treatment of breast cancer after surgery, as well as for metastasis in both pre and post-menopausal

women. The severity of breast cancer can be increased by estrogen, as sex hormones cause hyperplasia, and

differentiation at estrogen receptor sites. Anastrozole works by inhibiting the synthesis of estrogen. The patent on

Arimidex by AstraZeneca expired June 2010.

It is on the World Health Organization's List of Essential Medicines, a list of the most important medications needed

in a basic health system.

Function & Application

1. Anastrozole is an extremely powerful anti-estrogen officially belonging to the aromatase inhibitor (ai) family.

developed in the early 1990’s by zenaca pharmaceuticals and released in 1995 under the trade name arimidex,

this is perhaps the most commonly used ai and one of the most common anti-estrogens on the market.

2. Anastrozole has proven to be very effective in breast cancer treatment, even more so than traditional novadex

(tamoxifen citrate), and is a favorite anti-estrogen among many anabolic steroid users. countless anabolic steroid

users rely on arimidex for on cycle estrogenic protection. 

3. Many anabolic steroids have the ability to aromatase and lead to excess estrogen, which in turn can lead to

some of the most commonly associated side effects of anabolic steroid use.

4. As an anti-estrogen, anastrozole is valuable to the breast cancer patient as many forms of breast cancer feed

off of the estrogen hormone. while perhaps an oversimplification, by administering arimidex the effect starves

the cancer. 

5. For decades nolvadex was used for this purpose. nolvadex has the ability to bind to the estrogen receptors,

which in turn prevents estrogen from binding. 

6. However, ai’s like anastrozole actively inhibit the production of estrogen and reduce the actual amount of

circulating hormone. in short, there is no estrogen available to cause damage to the breast cancer patient.

7. Anastrozole has become the leading anti-estrogen in the treatment of hormone receptor-positive breast cancer,

especially among post-menopausal women. once the cancer has subsided, it is not uncommon for nolvadex to be

introduced in order to keep the cancer at bay.
