Aromatase inhibitor Wikipedia

Hormone-sensitive breast cancers are fueled by the natural hormones estrogen or progesterone. Although mostly a concern for people with metastatic breast cancer who get higher doses of bisphosphonates or denosumab, these drugs can cause bone, joint and muscle pain [115,122]. This type of pain usually only lasts for 1-2 days, and only with the first treatment. Additional studies are underway to determine whether aromatase inhibitors may reduce the risk of breast cancer in people with genetic mutations that increase breast cancer risk.

Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. Advise your oncologist about any medications you are taking, whether they are pharmaceutical, over-the-counter, recreational, or traditional to avoid drug interactions. Sign up to be a Komen Advocacy Insider and get informed when action is needed on drug coverage issues at the state or national level. Hormone therapy drug costs can quickly become a financial burden for you and your family. Our team is made up of doctors andoncology certified nurses with deep knowledge of cancer care as well as journalists, editors, and translators with extensive experience in medical writing.

This includes breast cancer surgery and possibly chemotherapy. Treatment with aromatase inhibitors can be started at the same time with radiation therapy. Aromatase inhibitors are a hormone therapy (also called endocrine therapy). They are used to treat hormone receptor-positive early, locally advanced and metastatic breast cancers. Firstly, it blocks oestrogen receptors, in a similar way to tamoxifen.

  • You might also have calcium and vitamin D supplements to help reduce the effect on your bones.
  • Fulvestrant is also approved for postmenopausal women with HR-positive, HER2-negative locally advanced or metastatic breast cancer who have not previously been treated with hormone therapy (11).
  • Because hormone-positive breast and ovarian cancers are dependent on estrogen for growth, AIs are taken to either block the production of estrogen or block the action of estrogen on receptors.
  • Komen supports state and federal efforts to require insurers to provide the same or better coverage for oral cancer drugs as they do for IV and injectable cancer drugs.

A small amount comes from the adrenal glands and other tissues. An enzyme called aromatase takes other hormones and converts them into estrogen. Depending on your circumstances, you may undergo tests to monitor your medical situation. These tests help watch for cancer recurrence or progression during hormone therapy. Results of these tests can give your oncologist an idea of how you’re responding to the treatment. All three aromatase inhibitors work the same way and reduce the production of estrogen in the body.

Aromatase is the enzyme that catalyzes a key aromatization step in the synthesis of estrogen. It converts the enone ring of androgen precursors such as testosterone, to a phenol, completing the synthesis of estrogen. Because hormone-positive breast and ovarian cancers are dependent on estrogen for growth, AIs are taken to either block the production of estrogen or block the action of estrogen on receptors. There is growing evidence that aromatase may benefit more than just postmenopausal women. A number of studies shown that the drugs may be beneficial in premenopausal women whose ovaries have suppressed with gonadotropin-releasing hormone agonists (GnHRa). A 2018 study in the Journal of Clinical Oncology also noted that the risk of diabetes was 240% greater in women on than in the general population.

Current research suggests at least five years of hormone therapy. You and your health care provider can work together to decide how long you should take them. Aromatase inhibitors are medicines that reduce the amount of estrogen in the body. This medicine deprives breast cancer cells of the hormones they need to grow. Tests in a lab can show whether the cancer cells have receptors for estrogen or progesterone.

Anastrozole – Brand name: Arimidex

LHRH drugs work by blocking a hormone made in the pituitary gland that stimulates your ovaries to make and release oestrogen. So you won’t have periods or release eggs while you are having the injections. Your doctor will think about your general health and possible side effects of the drugs when deciding which hormone treatment will be best for you. You might have hormone therapy when secondary breastcancer is first diagnosed. Surgery is the main treatment for breast cancer, but some women have health problems that mean they can’t have surgery. You have check ups with your doctor during neo adjuvant hormone therapy to see if your cancer is getting smaller.

Who can and cannot take anastrozole

Most people who take anastrozole will have had surgery, radiotherapy or sometimes chemotherapy to treat their breast cancer first. It works by lowering the levels of oestrogen hormones in your body. However, there’s not enough research to conclude that breast cancer patients can replace aromatase inhibitors with grape seed extract or other dietary choices, cautions Proctor.
