Xtandi, or Enzalutamide, is used to treat cancer of the prostate. It belongs to a class of drugs known as androgen receptor inhibitors, which target the androgen receptor, which plays an essential role in prostate cancer development.

It occurs when prostate cancer persists despite suppressed testosterone levels, which usually fuel cancer growth.

In addition to blocking the androgen receptor, Xtandi is a magnet for male hormones such as testosterone. Prostate cancer cells are effectively inhibited from growing and multiplying when Xtandi blocks this receptor.

Once a day, this medication is taken by mouth as a capsule. There is only one strength available: 40 mg.
