Men who have prostate cancer that has spread or returned after previous treatment may receive a chemotherapy drug called enzalutamide. This prescription medicine comes as a capsule that is taken once a day. It works by preventing testosterone from stimulating the cancer. People who have a history of seizures, strokes, or certain other medical conditions may not be able to safely use this drug.
What Is Enzalutamide?
Enzalutamide (Xtandi®) is a prescription medication approved to treat castration-resistant prostate cancer that has spread to other parts of the body. Castration-resistant prostate cancer is prostate cancer that has returned or progressed despite medical or surgical treatments to lower testosterone levels. Enzalutamide is approved for use in men who have previously been treated with a chemotherapy medicine known as docetaxel (Docefrez™, Taxotere®).
