If you’re interested in this option, check with your doctor, pharmacist, or insurance provider. If you still have questions about the cost of exemestane, talk with your doctor or pharmacist. They may be able to give you a better idea of what you’ll pay for this drug. But if you have health insurance, you’ll need to talk with your insurance provider to learn the actual cost you’ll pay for exemestane.
Not only did these treatments have more side effects, but the chances of recurrence of breast cancer were also high. The development in medical science has led to the establishment of various novel treatments, one of which is the use of Aromatase Inhibitors. This article will help you in giving a detailed overview of the role of aromatase inhibitors in breast cancer therapy. To our knowledge, there is a conflict regarding the use of AIs and subsequent SCLE or SLE prevalence. So far, some data suggest that antiestrogen therapy may have beneficial effects in patients with SLE, while there are studies showing increased incidence of rheumatic diseases with the use of both SERMS and AIs 33.

- It is thought that the relative proportions of each determine whether the ligand will act as an oestrogen or an antioestrogen for a specific gene.
- If the above recommendations are not effective, a vaginal dilator may ease dyspareunia.

- Clinical trials have shown that aromatase inhibitors are about 30% more effective in preventing breast cancer recurrence than tamoxifen or raloxifene.
Aromatase inhibitors inhibit the aromatization step in estrogen synthesis, converting androgen precursors like testosterone to phenols. Hormone-positive breast and ovarian cancers rely on estrogen for growth, so AIs block estrogen production or estrogen’s action on receptors. Hot flashes and night sweats are common in women who take aromatase inhibitors 105. Aromatase inhibitors cause a loss of bone density, which leads to higher rates of osteoporosis and bone fractures compared to tamoxifen 10,120.

Assessment of the role of complementary approaches in adjuvant breast cancer treatment relies Steroids buy on adequate participation in clinical trials. Recruitment to clinical trials has always been challenging (45), and non-therapeutic trials offer less incentive for patients diagnosed with life-threatening diseases such as cancer. Our target population was postmenopausal women with stage I or II ER+ breast cancer, as these are the patients who would be prescribed aromatase inhibitors.
Although the FDA has not yet approved aromatase inhibitors for any of these purposes, many believe that supporting research will one day broaden the current treatment recommendations. Some interactions may decrease the concentration of the aromatase inhibitor in the blood and require a dose adjustment to compensate for the effect. These losses can lead to osteoporosis, a condition characterized by the collapse of spinal vertebras, stooped posture, a loss of height, and an increased risk of bone fractures. Aromatase inhibitors work by binding to aromatase and preventing aromatization from occurring. By doing so, the production of estrogen may be reduced by as much as 95% in postmenopausal women. Aromatase inhibitors block a process that occurs within these cells called aromatization—the conversion of the male hormone testosterone into estrone and estradiol (the two primary forms of estrogen) via an enzyme known as aromatase.
When an aromatase inhibitor is taken after tamoxifen, the drugs are taken for a combined total of 5-10 years. The adoption of costly treatments in public health care systems, such as exists in Canada, must take into account their “clinical benefit to side effect” profiles and “value for money” in an attempt to maximize health gains within current budget constraints. The demographic and clinical characteristics of study participants are summarized in Table 1.
