Aromasin 25 mg per day resulted in a 5-year disease-free survival rate of 88%, but ranged between 85. 8% and 89. 9% of women. Femara 2. 5 mg per day led to a 5-year disease-free survival rate in 89. 4%, with a range between 87. 3% to 91. 1% of women. Survival rate is the number of patients still alive at the conclusion of a study.
By lowering estrogen levels in the body, these medications help slow or stop the growth of breast cancer cells. Arimidex and Aromasin can only be obtained with a prescription. Continue reading to learn more about the similarities and differences between Arimidex and Aromasin. What are the main differences between Arimidex and Aromasin?
Hormone therapy (also called hormonal therapy, hormone treatment, or endocrine therapy) slows or stops the growth of hormone-sensitive tumors by blocking the body's ability to produce hormones or by interfering with effects of hormones on breast cancer cells.
. The three aromatase inhibitor drugs are: Letrozole Anastrozole Exemestane Men with breast cancer may be given an aromatase inhibitor, although another drug called tamoxifen is more commonly used. 2. Is there a difference between letrozole, anastrozole and exemestane?
Aromatase inhibitors (AIs), like arimidex, aromasin and femara, are also used to help fight cancer cell regrowth. These drugs work to block cell receptors like estrogen and progesterone in breast cancers that are hormone receptor positive. Aromatase inhibitors have similar side effects to those of Tamoxifen but also affect bone health.
Top 5 anastrozole alternatives The following are some of the most common alternatives to anastrozole. 1. Femara (letrozole) Femara is the brand name of the medication letrozole and is another type of aromatase inhibitor. Like anastrozole, letrozole is nonsteroidal and used to treat hormone receptor-positive breast cancer in postmenopausal women.
The AIs are divided into steroidal inactivators (exemestane) and nonsteroidal inhibitors (letrozole, anastrozole). Exemestane is a steroidal analogue of androstenedione and binds irreversibly to aromatase . Nonsteroidal inhibitors, like letrozole or anastrozole, bind reversibly to the heme group of the enzyme by way of a basic nitrogen atom.
The steroidal inhibitor exemestane is partially non-cross-resistant with nonsteroidal aromatase inhibitors and is a mild androgen and could prove superior to anastrozole regarding efficacy and toxicity, specifically with less bone loss.
Doctors & Departments Overview Hormone therapy for breast cancer is a treatment for breast cancers that are sensitive to hormones. Some forms of hormone therapy for breast cancer work by blocking hormones from attaching to receptors on cancer cells. Other forms work by decreasing the body's production of hormones.
Aromasin (exemestane) and Femara (letrozole) are both aromatase inhibitors (third generation) and are used to treat specific forms of breast cancer. If breast cancer growth is increased by estrogen then the breast cancer is called estrogen dependent (or sometimes called ER-positive breast cancer).
Results In the study, 7,576 women (median age, 64. 1 years) were enrolled. At median follow-up of 4. 1 years, 4-year EFS was 91% for exemestane and 91. 2% for anastrozole (stratified hazard ratio, 1. 02; 95% CI, 0. 87 to 1. 18; P = . 85). Overall, distant disease-free survival and disease-specific survival were also similar.
These third-generation aromatase inhibitors (letrozole/Femara (Novartis Pharmaceuticals, Basel, Switzerland) and anastrozole/Arimidex (AstraZeneca, Pharmaceuticals, Macclesfield, Cheshire, UK .
Anastrozole and letrozole are two non-steroidal aromatase inhibitors that are widely used to treat breast cancer. However, they have different pharmacokinetic and pharmacodynamic properties that may affect their efficacy and safety. This article reviews the evidence on the differences between these two drugs and their clinical implications for breast cancer patients who need to reduce estrogen .

Published on August 27, 2021 Key takeaways: Anastrozole (Arimidex) and exemestane (Aromasin) are aromatase inhibitors (AIs) used for treating estrogen receptor-positive (ER+) breast cancer in people who have gone through menopause. Research shows that both anastrozole and exemestane are similarly effective in achieving cancer-free survival.

The aromatase inhibitors anastrozole (Arimidex), exemestane (Aromasin) and letrozole (Femara) all have a similar treatment benefit [1]. They also have similar side effects. However, a person may tolerate one drug better than another. Learn more about aromatase inhibitors, including possible side effects.
Steroidal inhibitors such as formestane and exemestane inhibit aromatase activity by mimicking the substrate androstenedione. Nonsteroidal enzyme inhibitors such as anastrozole and letrozole inhibit enzyme activity by binding with the heme iron of the enzyme. First-generation aromatase inhibitors such as aminoglutethimide are relatively weak .
Aromatase inhibitors are a class of medicines that reduce the amount of estrogen in your body, depriving breast cancer cells of the fuel they need to grow and thrive. Three aromatase inhibitors are currently approved in the United States for breast cancer treatment: anastrozole (Arimidex), exemestane (Aromasin) and letrozole (Femara).
Uncertainty exists about the optimal schedule of adjuvant treatment of breast cancer with aromatase inhibitors and, to our knowledge, no trial has directly compared the three aromatase inhibitors anastrozole, exemestane, and letrozole.
Aromasin is the brand name of the drug Exemestane. It too is an AI (Aromatase Inhibitor) just as Arimidex is. The difference, however, is that this one is steroidal, as opposed to Arimidex, which is a non-steroidal AI. This drug, it should come as no surprise to learn, was developed for medical purposes and as a result, it is legally available .
