1. What is Enzalutamide Sandoz and what is it used for

Enzalutamide Sandoz contains the active substance enzalutamide. Enzalutamide is used to treat adult men with prostate cancer:

• that has stopped responding to hormone therapy or surgical treatment to reduce testosterone,

or

• that has spread to other parts of the body and responds to hormone therapy or surgical treatment to reduce testosterone,

or

• who have undergone prior prostate removal or radiation and have a rapid increase in PSA, but the cancer has not spread to other parts of the body and responds to hormone therapy to reduce testosterone.

How Enzalutamide works

Enzalutamide is a medicine that works by blocking the activity of certain hormones called androgens (such as testosterone). By blocking androgens, enzalutamide causes prostate cancer cells to stop growing and dividing.
