What is Exemestane (107868-30-4) used for?

Exemestane is a medication used in the United States for specific medical purposes. Its primary use is related to the treatment of hormone receptor-positive breast cancer, particularly in postmenopausal women. Here are its main uses:

Breast Cancer Treatment: Exemestane is primarily prescribed as an adjuvant treatment for postmenopausal women with early-stage breast cancer. It is often recommended following surgery, radiation, or other therapies to reduce the risk of cancer recurrence. Exemestane works by inhibiting the production of estrogen in the body, as estrogen can promote the growth of hormone receptor-positive breast tumors.

Advanced Breast Cancer: In cases of advanced or metastatic breast cancer, where the cancer has spread to other parts of the body, Exemestane may be used to slow down the progression of the disease. It is commonly prescribed when other hormonal therapies have not been effective.
