A non-steroidal aromatase inhibitor called Arimidex (anastrozole) is used to treat breast cancer in women after menopause. Arimidex works by lowering estrogen levels in the body, which aids in reducing breast tumor size and growth. Usually, one dose of arimidex is taken each day, with or without food.

Health Benefits

It has been demonstrated that Arimidex works well in the treatment of breast cancer. Arimidex has been demonstrated to significantly lower by 65% the risk of the cancer returning or spreading in postmenopausal women with early-stage breast cancer who participated in a clinical trial. Compared to tamoxifen, arimidex also delayed the progression of the cancer and had fewer adverse effects.

Other hormone-sensitive cancers, like ovarian, endometrial, and prostate cancers, may also be treated with arimidex.

Side Effects

Hot flashes, joint pain, fatigue, and nausea are some of the most typical side effects of Arimidex. Additionally, arimidex may elevate cholesterol levels. Weight gain, bone pain, depression, and headache are less common side effects.

Call your doctor right away if you experience any of the following side effects:

- Breathing problems

- Facial, throat, tongue, lip, eye, hand, foot, ankle, or lower leg swelling

- Rash or hives

- scratching

- breathing or swallowing issues

- a hoarse voice

Mechanism of Action

Arimidex works by preventing the enzyme aromatase, which is in charge of turning testosterone into estrogen, from doing its job.Arimidex lessens the body's estrogen levels, which in turn slows the development and enlargement of breast tumors.

Dosage and Administration

The dosages of Arimidex tablets are 0.5 mg and 1 mg. Arimidex should be taken once daily with one tablet.

You can take arimidex with or without food. Take Arimidex with food if you experience nausea while taking it.

Take Arimidex as soon as you remember if you miss a dose. Skip the missed dose and carry on with your regular schedule if it is almost time for your next dose. Never take two doses of Arimidex at once.


Tamoxifen, warfarin, and estrogen-containing drugs may all interact with arimidex. Any medication you take should be disclosed to your doctor. Pregnancy should not be the time to take Arimidex.


Arimidex is quickly absorbed after being taken orally. Within 3 to 4 hours, Arimidex reaches its highest blood concentration. The body widely distributes arimidex, which is 99% bound to plasma proteins. CYP3A4 breaks down arimidex in the liver. The urine and feces are where Arimidex's metabolites are eliminated.
