Abiraterone Acetate is a hormonal therapy that is used to stop the essential function of the tumor. The growth of prostate cancer cells is mainly stimulated by androgen or testosterone. If there is any interference that stops the production of these hormones then the survival rate of prostate cancer increases.
Zytiga interferes with the activity of an enzyme that is expressed in adrenal testicular and prostatic tumor tissues, which is one of the major parts of the body's androgen producing process. When this activity is handed then the production decreases. It blocked the androgen production from three different sources; adrenal gland testis as well as from the tumor cells.
