Abstract

Androgen deprivation is the mainstay therapy for metastatic prostate cancer. Another way of suppressing androgen receptor signaling is via AR antagonists or antiandrogens. Despite being frequently prescribed in clinical practice, there is conflicting evidence concerning the role of AR antagonists in the management of prostate cancer. In the castrate resistant settings of prostate cancer, docetaxel has been the only treatment option for decades. With recent evidence that castrate resistant prostate cancer is far from AR-independent, there has been an increasing interest in developing new AR antagonists. This review gives a concise overview of the clinically available antiandrogens and the experimental AR antagonists that tackle androgen action with a different approach.
