What is apalutamide?

Apalutamide is to treat prostate cancer that has spread to other parts of the body (metastatic) and still responds to a medical or surgical treatment that lowers testosterone.

Apalutamide is also used to treat prostate >cancer that has not spread to other parts of the body, after surgery or other treatments did not work or have stopped working.

Apalutamide belongs to a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of cancer cells.

This medicine is not approved for use in women or children.
