Aromatase Inhibitors AIs: Definition, Uses, Side Effects, and More
This treatment arm was discontinued from the trial see ClinicalStudies. Based on clinical and pharmacokinetic results from the ATACtrial, tamoxifen should not be administered with anastrozole. Hormone therapy is sometimes used for the neoadjuvant treatment of HR-positive breast cancer in postmenopausal women who cannot tolerate chemotherapy or when surgery needs to be delayed. Estrogen and progesterone also promote the growth of some breast cancers, which are called hormone-sensitive (or hormone-dependent) breast cancers.
Aromasin side effects
- Aromatase can start to work soon after you take your first dose.
- Both are prescribed with hormone therapy, specifically an aromatase inhibitor drug or fulvestrant (Faslodex).
- Trastuzumab (Herceptin) is the most common medicine used to treat HER2-positive breast cancer.
- Other tips for managing nausea include eating small amounts throughout the day (instead of having three main meals) and avoiding greasy or fatty foods.
- Docetaxel is indicated for use in combination with doxorubicin and cyclophosphamide for adjuvant treatment of operable node-positive breast cancer.
The safety and effectiveness of Aromasin haven’t been tested in children. Serious side effects from Aromasin aren’t common, but they can occur. But if they become more severe or don’t go away, https://www.pintoressolidarios.org/danabol-50-mg-balkan-pharmaceuticals-2/ talk with your doctor or pharmacist. These lists contain examples of serious side effects that can occur with Aromasin, with Arimidex, or with both drugs (when taken individually).

People who are suffering from breast cancer should always stay updated on recent breakthroughs in cancer treatment and consult oncologists for expert care. It belongs to the medication class known as aromatase inhibitors It is used to treat hormone-dependent breast cancer in postmenopausal women. Currently, AIs—which include the drugs anastrozole, exemestane, and letrozole—are only FDA-approved for breast cancer treatment, not prevention, but there have been a number of promising studies.
Letrozole (Femara)is in a class of medications called aromatase inhibitors. Letrozole (Femara) works by decreasing the amount of estrogen produced by the body. Letrozole (Femara) is used treat early breast cancer in women who have experienced menopause and who have had other treatments, such as radiation or surgery to remove the tumor.
These often contain phytoestrogens (plant oestrogens) and the safety of taking these supplements with hormone therapy for breast cancer has not been established. Patients should talk with their oncologist about the benefits of taking aromatase inhibitors for a longer duration than five years. This is balanced with a higher risk of bone-related side effects.
If you have any questions about eating certain foods with Aromasin, talk with your doctor. For more about possible side effects of Aromasin, see the “Aromasin side effects” section above. And if you want more information on how alcohol may affect Aromasin, talk with your doctor or pharmacist. They can tell you how much alcohol is safe for you to drink during your treatment. The safety and effectiveness of Aromasin in children hasn’t been studied.
Effectiveness for breast cancer
Prior therapy should have included an anthracycline and a taxane in either the adjuvant or the metastatic setting. Epirubicin is indicated as a part of adjuvant therapy in patients with evidence of axillary-node tumor involvement after resection of primary breast cancer. 142 It can be used as a single agent, but such use is much less common in the setting of recurrent or metastatic disease. Epirubicin is a cell cycle phase inhibitor–nonspecific anthracycline derivative of doxorubicin with maximum cytotoxic effects on the S and G2 phases of the cell cycle. Arimidex (anastrozole) is a non-steroidal aromatase inhibitor used to treat breast cancer in postmenopausal women. Arimidex is often given to women whose cancer has progressed even after taking tamoxifen (Nolvadex, Soltamox).
It is also a possible treatment for breast cancer that has spread to other parts of the body. Protocol B-33 of the National Surgical Adjuvant Breast and Bowel Project (NSABP) is randomizing patients who are disease-free after 5 years of tamoxifen to 2 years of either exemestane or placebo. The survival benefit in this study was interpreted cautiously, as it was evident only in patients who received the lower, 1 mg dose.
These results open a new avenue for the treatment of these de novo endocrine resistant breast cancers. Anastrozole significantly lowers serum estradiol concentrations by inhibiting the conversion of adrenally generated androstenedione to estrone. It is used as first-line treatment of breast cancer in postmenopausal women with hormone receptor–positive or hormone receptor–unknown locally advanced or metastatic disease. It is also used to treat advanced breast cancer in postmenopausal women with disease progression after tamoxifen therapy. Studies conducted using in vitro and in vivo models have demonstrated that letrozole is the most potent of the third-generation AIs.
