Abiraterone acetate, sold under the brand name Zytiga among others, is a medication used to treat prostate cancer.[1] Specifically it is used together with a corticosteroid for metastatic castration-resistant prostate cancer (mCRPC) and metastatic high-risk castration-sensitive prostate cancer (mCSPC).[2][3] It should either be used following removal of the testicles or along with a gonadotropin-releasing hormone (GnRH) analog.[2] It is taken by mouth.[9]
