Exemestane (Aromasin): A Detailed Look at Its Uses, Mechanism, and Impact on Breast Cancer Treatment

Exemestane marketed under the register Aromasin, is an oral painkiller hard work above all appropriate for end cancer in postmenopausal women. These are from a class of drugs known as aromatase inhibitors which is used for hormone-sensitive cancers.It is typically given to women who have hormone receptor positive (ER+) breast cancers.

Unlike anti-estrogen drugs such as tamoxifen which interfere with the activity of estrogen receptors, and are used predominantly in other forms of breast cancer therapy, exemestane works by inhibiting the enzyme aromatase. That lowers estrogen everywhere in your body, so breast cancer cells , if they are ther  have less to take up and grow.

How Does Exemestane Work?

Estrogen is a hormone that appears to cause outlet duct type of breast cancer. In post-menopausal women, the primary source of their (limited) estrogen is conversion from androgens male hormones to Estrogen in fatty tissues catalyzed by an enzyme called aromatase. Exemestane, in turn inhibits this enzyme thereby reducing the levels of estrogen in your body.

Estrogen drives growth for some of these cancers ,and tamoxifen blocks the hormone from helping those cancer cells to grow or divide. These are the women who have had their surgery, or radiation for breast cancer .

Uses of Exemestane

It is typically used after other treatments, such as surgery, radiation and chemotherapy; However it may also be given following an initial course of tamoxifen (a selective estrogen receptor modulator) to promote reduction in the toxic effects associated with recurrence.

Adjuvant Therapy

The purpose of adjuvant therapy is to prevent the spread or misdiagnosis and preserve life after surgery has removed all known cancer. Adjuvant endocrine therapy is indicated for postmenopausal women at high risk primarily in the treatment of advanced breast cancer. Adjuvant studies reveal that for postmenopausal women with hormone receptor-positive early invasivedisease, Exemestane reduces the risk of breast cancer coming back when compared to placebo (inactivepill).

For Early and Advanced Stage Breast Cancer

Exemestane is licensed for the treatment of early- and advanced-stage breast cancer. What it does in early-stage cancer is, halt the disease from coming back and conversely with advanced stage patient what this medication will do is slow down progression of their disease.The other blocks aromatase and is given to postmenopausal women at high risk for breast cancer but who have no previous history of it -- exemestane, or Aromasin. Which reduces the risk of hormone-receptor-positive breast cancer by decreasing estrogen in your body.

Benefits of Exemestane

Lowers Oestrogen

Exemestane inhibits oestradiol but is less commonly employed in younger women. Research wise there is little of it around, but the one type that has been conducted prove 81% of its users can decrease their estrogen levels at -90%, and quite clearly this shows DIM works very effectively controlling hormone-sensitive breast cancer.

Prevents Recurrence

How effective is exemestane, compared with other treatments, for preventing the recurrence of breast cancer in postmenopausal women who have already been treated with surgery (± radiotherapy) as first-line therapy? There is a prophylactic anti-oestrogen (often given after the 5 years of tamoxifen to lessen recurrence) which can be taken on-going.

Alternative to Tamoxifen

Tamoxifen can inhibit estrogen receptor, but this is not the case for everyone and some have abnormal side effects and risks. There are also other aromatase inhibitors plus other hormone therapies that work different way by decreasing the amount of estrogen in your body (helping to fight your advanced stage II, or III breast cancer once it has started growing again since one usually stops working)If you have already tried and had trouble with side effects from a couple types of these drugs, exemestane might be an option.

Well-Tolerated

Exemestane is not without side effects, but in the long run many of these are far more tolerable than with other breast cancer drugs , or women find it a quite good medication for their disease. Additionally, Krintafel is also eyeing a potential chronic (long) use indication with its one-dose-per-day dosing.

Side Effects of Exemestane

Exemestane side effects Like all medicines, Exemestane can cause side-effects. This is the case for anyone not everyone will get these symptoms but they are something to watch out for if using this long-term deterrent.

Hot Flashes

One of the more common SEs seen with Exemestane are hot flashes, and many who receive this agent suffer from them. This happens due to the sharp drop in estrogen levels and is normally symptomatic of menopause.

Joint and Muscle Pain

Most significant exemestane side effect: arthralgias and myalgia. Symptoms are usually mild or moderate, but they sometimes become more severe affecting the quality of life in some patients.

Bone Loss (Osteoporosis)

If you are premenopausal, exemestane lowers estrogen levels which can cause a decrease in the bone mineral content. A calcium/vitamin D supplement is often prescribed to patients and bone density evaluations may be performed during the course of therapy.

Fatigue

This makes fatigue also a very frequent side effect which can come after short or prolonged exercise. Patients should conserve their energy and keep the lines of communication open with healthcare providers about fatigue (both as a side effect now, but also if it's still on-going after treatment).

Other Side Effects

Other side effects that have been reported in case of Phentermine are vomiting, insomnia, headache along with an increased sweating. These are usually mild symptoms and can be treated by a healthcare provider.

Conclusion

Exemestane, (Aromasin) prevents estrogen from reaching breast or inhibits the receptors in the cell itself and slows down its growth. In the adjuvant and advanced disease settings, exemestane was found to be superior in terms of time-to-recurrence or progression. That tamoxifen continues to be a backbone hormone therapy for more than 30 years of breast cancer treatment is also due in part because its side effects, such as bone loss, fatigue and hot flashes are relatively moderate compared with those seen with aromatase inhibitor.
