Enzalutamide (brand name- Xtandi) is an FDA-approved treatment for prostate cancer in men that no longer responds to hormone therapy or surgical treatment to lower testosterone and has spread to other body parts. It is unknown whether it is safe and effective in females and children.
Enzalutamide belongs to a class of medicines called anti-androgens. By blocking testosterone, enzalutamide helps slow down the growth of prostate cancer cells. It also helps to shrink the tumor and reduce the symptoms of prostate cancer.
Let us walk you through the key things you need to know about Enzalutamide.
