About Arimidex 1mg

Arimidex, also known as an aromatase inhibitor, works by inhibiting the activity of aromatase, suppressing the production of estrogen and suppressing the growth of breast cancer.

In clinical trials, once-daily administration to postmenopausal advanced breast cancer patients reported that aromatase activity was inhibited by approximately 96%. In addition, in postmenopausal hormone-sensitive breast cancer, clinical results have been reported to surpass those of the anti-estrogen drug tamoxifen (Nolvadex), so it can be said to be a drug of the new generation.

A drug used in postmenopausal hormone therapy

In breast cancer, the goal is radical cure by resection, but drug therapy also plays an important role.

There are two main types of drug therapy: hormone therapy and chemotherapy using anticancer drugs.

Hormone therapy is a treatment that attempts to suppress the growth of breast cancer by using hormone-related drugs to reduce the effects of female hormones (estrogens). By performing it after surgery, it can be expected to have the effect of preventing recurrence, and it can be expected to have the effect of suppressing the progression of advanced or recurrent breast cancer.

Treatment methods vary depending on the purpose of treatment, the type of breast cancer, whether it is premenopausal or postmenopausal, the degree of progression, and the degree of malignancy.

It has the effect of suppressing the growth of breast cancer

The female hormone (estrogen) that promotes the growth of breast cancer cells is produced in different places before and after menopause.

In premenopausal women, it is mainly produced by the ovaries, but in postmenopausal women, the ovaries cannot produce it because the ovarian function has decreased. Instead, a small amount of estrogen is produced by the action of an enzyme called aromatase on male hormones (androgens) produced by the adrenal glands.

This is why different medications may be used for premenopausal and postmenopausal women.

Some breast cancers require estrogen for the proliferation of cancer cells, and account for 60-70% of all breast cancers.

Arimidex inhibits the production of estrogen in the body by inhibiting aromatase activity, thus inhibiting the growth of breast cancer.

Contains the active ingredient Anastrozole

The active ingredient anastrozole inhibits the production of estrogen from androgens by inhibiting the activity of aromatase, thereby suppressing the growth of breast cancer. After menopause, estrogen is produced from androgens (male sex hormones) in the adrenal glands via an enzyme called aromatase.

Anastrozole works by inactivating aromatase, which reduces the production of estrogen. Because of these actions, they are also called aromatase inhibitors.
