Abiraterone is a new type of hormone therapy. It is also called abiraterone acetate, CB7630 or Zytiga. It is used to treat prostate cancer that has spread to other parts of the body. It may help some men to live longer. It can also help control symptoms. Clinical trials are also using abiraterone for earlier stages of prostate cancer and advanced breast cancer. Abiraterone is associated with a not uncommon rate of serum enzyme elevation during therapy, but has not been clearly linked to cases of clinically apparent liver injury with jaundice.
