Anastrozole. For what purposes is it used?


All you need to know about AnastrozoleThe main purpose of using Anastrozole is the breast cancer treatment. This drug in the form of oral tablets is often prescribed to women who have a diagnosis of a breast cancer and have already gone through menopause. It is an effective drug which is used both in case of early breast cancer and advanced breast cancer treatment. Also, it is prescribed for the treatment of breast cancer with metastases (in a case when cancer has spread to other organs or part of the body). This drug is prohibited for taking by women who haven’t got through the menopause yet. In a case when you become pregnant when taking this medication, you have to stop it’s taking immediately, otherwise, it can be dangerous both for you and your child.

The mechanism of Anastrozole’s action is based on the blocking of the estrogen production. Being the aromatase inhibitor, Anastrozole maximally blocks the production of a female hormone – estrogen, which is one of the main factors that stimulate the breast cancer.

In the organisms of postmenopausal women, a special hormone – androgen under the influence of the aromatase enzyme transforms into the estrogen hormone. The mechanism of the Anastrozole’s action is aimed at the blocking the work of this enzyme, thereby significantly decreasing the amount of the estrogen produced.

Also, this medication is actively used in sport by professional bodybuilders. The main goal of the Anastrozole course is to avoid water retention in the body, gynecomastia and a number of other side effects that occur after the end of a long course of taking serious anabolic steroids.

Anastrozole has a very pronounced effect: 1 mg of this substance can reduce the content of estradiol in the blood by 80%. Even such a popular drug as Tamoxifen does not have such a powerful effect. However, comparing these two drugs is not correct, because the principle of their action is completely different. Effects of the Anastrozole use:

·A serious reduction in the level of aromatization (up to 80 percent of the initial level).

·Blocking the estrogen synthesis.

·Significant inhibitory effect.

·Rapid effect of the drug. The limiting concentration of the active substance in the blood can be observed already after 2 hours after use, which makes it possible to stop the aromatization process very quickly.

·It is extremely effective for athletes with a tendency to aromatize.
