Abiraterone acetate, sold under the brand name Zytiga among others, is a medication used to treat prostate cancer.[9] 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]

Common side effects include tiredness, vomiting, headache, joint pain, high blood pressure, swelling, low blood potassium, high blood sugar, hot flashes, diarrhea, and cough.[9][2] Other severe side effects may include liver failure and adrenocortical insufficiency.[2] In males whose partners can become pregnant, birth control is recommended.[2] Supplied as abiraterone acetate it is converted in the body to abiraterone.[2] Abiraterone acetate works by suppressing the production of androgens – specifically it inhibits CYP17A1 – and thereby decreases the production of testosterone.[9] In doing so, it prevents the effects of these hormones in prostate cancer.[9]

Abiraterone acetate was described in 1995, and approved for medical use in the United States and the European Union in 2011.[10][2] It is on the World Health Organization's List of Essential Medicines.[11][12] It is available as a generic medication.[13]
