ARIMIDEX Information

Learn about ARIMIDEX

If you have been newly diagnosed with breast cancer or are new to hormonal treatment, it’s time to learn how ARIMIDEX may help reduce your risk of breast cancer recurrence.

ARIMIDEX is a prescription medicine approved for postmenopausal women with hormone receptor-positive early breast cancer. ARIMIDEX is a hormonal treatment that helps fight breast cancer by lowering the amount of the hormone estrogen in the body.

Ask your doctor about ARIMIDEX, the most prescribed aromatase inhibitor.*

The science of ARIMIDEX

Series of reactions

Click to enlarge

In a complex series of reactions, the adrenal gland makes certain hormones, including androgens (male hormones) and estrogens (female hormones)

Androgens

Click to enlarge

When women have gone through menopause, their ovaries no longer make estrogen. Most of their estrogen is created by changing the androgens to estrogens. An enzyme called aromatase helps in this process. Androgens change to estrogens in various places in the body, such as in muscle, fat, and the liver, and also in breast tumors

Tumor growth

Some breast cancer tumors grow when the hormone estrogen is present. ARIMIDEX binds to aromatase, stopping — or inhibiting — aromatase activity and the production of estrogen. For this reason, ARIMIDEX is called an aromatase inhibitor

  • ARIMIDEX significantly lowers the concentration of certain estrogens in your body.

Side effect profile

ARIMIDEX offers women who’ve had breast cancer proven, powerful protection against recurrence, while being less likely to cause certain side effects than tamoxifen. Patients taking ARIMIDEX were less likely than those taking tamoxifen to stop treatment because of side effects. See Important Safety Information below, and talk to your doctor to see if ARIMIDEX is right for you.

In the early breast cancer clinical trial, the most common side effects seen with ARIMIDEX include hot flashes, joint symptoms, weakness, mood changes, pain, sore throat, nausea and vomiting, depression, high blood pressure, osteoporosis, swelling of arms/legs and headache. Fractures (including fractures of the spine, hip, and wrist) occurred more frequently with ARIMIDEX than with tamoxifen (10% vs 7%).
