Exemestane is used in the adjuvant treatment of hormonally-responsive breast cancer in postmenopausal women. It irreversibly binds to the active site of the enzyme resulting in permanent inhibition. It is an oral steroidal aromatase inhibitor.. Reference standards of Exemestane API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below
