Comparing Aromatase Inhibitors: Which Has the Least Side Effects?
Ask your doctor what other medications are better options for you. Arimidex may not be right for you if you have certain medical conditions or other factors that affect your health. Talk with your doctor about your health history before you take Arimidex. If your doctor confirms you had a serious allergic reaction to Arimidex, they may have you switch to a different treatment. For example, they may recommend taking an OTC pain reliever, such as acetaminophen or ibuprofen, to help ease this side effect. In some rare cases, side effects can result in permanent damage, even after you stop treatment with Arimidex.
One day last summer, when I was recuperating following my DIEP surgery, it hit me – I was feeling better – regarding AI side effects. I haven’t written about the drugs we love to hate in a while and thought it was time I did. I’m sharing a couple personal updates as well as a couple research-backed updates about these drugs, or more specifically, the management of side effects from said drugs. Living Beyond Breast Cancer is a national nonprofit organization that Halotestox 5 mg P&B Labs seeks to create a world that understands there is more than one way to have breast cancer. To fulfill its mission of providing trusted information and a community of support to those impacted by the disease, Living Beyond Breast Cancer offers on-demand emotional, practical, and evidence-based content.
- In the brain, estradiol synthesis is increased in areas related to sexual arousal.
- This review article summarizes the structure and function of aromatase enzyme, discovery and evolution of AIs, clinical efficacy of AIs, and recent insights into the mechanisms of AI resistance.
- Most of these side effects are reduced with acupuncture (Hershman et al., 2018) or manageable through multiple methods.
- From protein powders to creatine, there are many different over-the-counter supplements that you can try that are aimed at putting on muscle mass, losing fat, and overall keeping you healthy.
- Nevertheless, the benefit of AIs is often limited by the emergence of resistance.
- When given before surgery to shrink a tumor, it’s called neoadjuvant hormonal therapy.
Aromasin vs. letrozole
If you have ER-positive breast cancer, aromatase inhibitor therapy significantly reduces your risk that breast cancer will come back. One early study compared outcomes for those who took the aromatase inhibitor letrozole after tamoxifen and people who didn’t. The study showed that taking letrozole reduced the risk of dying of breast cancer by 24% to 35%.
For acquired resistance to AIs, we have developed an intratumoral aromatase breast cancer model to evaluate mechanisms of resistance to different AIs 12, 89. This model mimics hormone receptor-positive breast cancer in postmenopausal women. In our experiments, xenografts with tumors of MCF-7 cells overexpressing aromatase (MCF-7Ca) were treated with letrozole and tumors were collected at different time points 90. We found that by 28 weeks after treatment, there was a significant decrease in total ERα expression. However, the levels of phosphorylated ERα (p-ERα) in letrozole-resistant tumors were significantly higher than p-ERα level at baseline.

The catalytic portion of cytochrome P450 aromatase contains a heme group as well as a steroid binding site 29. There are still several areas of aromatase function that are not thoroughly understood, such as the third aromatization step, as well as the underlying reason for its high substrate specificity. To address this, some investigators have utilized homology models of aromatase, based on other P450 enzyme structures 30.
It does this via three oxidation reactions of the androstenedione A ring, with each reaction consuming a molecule of both oxygen and NADPH per reaction. Of these three steps, the third is unique to aromatase, while the first two are common to P450 cytochrome proteins 19. Breast cancer tissues have been shown to express aromatase and produce higher levels of estrogens than non-cancerous cells.
All the treatments that stop your ovaries working give you an early menopause, but this might be temporary with goserelin. You are likely to have menopausal symptoms that start very suddenly. Check what is the name of the hormone therapy with your doctor or nurse, then take a look at our A to Z list of cancer drugs.
For instance, some interactions can interfere with how well a drug works. Other interactions can increase the number of side effects or make them more severe. Researchers found that the 2.2% of women who took Aromasin had a complete response compared with 1.2% of women who took megestrol acetate. A partial response was seen in 12.8% of women who took Aromasin compared with 11.2% of women who took megestrol acetate. You should take Aromasin according to your doctor’s or healthcare provider’s instructions.
Most men think of estrogen as an exclusively female hormone, but You know what?! Testosterone is the precursor of estradiol, an estrogen, and the primary female sex hormone. Although these symptoms may become less frequent and less intense over time, they can still be hard to manage. Weight-bearing exercise (exercise that involves standing rather than sitting, such as walking and dancing) and resistance training (such as lifting weights and lunges) can help strengthen and protect your bones 140. How long a medication remains good can depend on many factors, including how and where you store the medication.
