SORASAB (Abiraterone) acetate classified as an “adrenal inhibitor” interferes with an enzyme that is expressed in testicular, adrenal, and prostatic tumor tissues and is required as part of the body’s androgen producing process. Because of this interference, the amount of androgens produced are decreased. Abiraterone acetate blocks androgen production at three sources; the testes, the adrenal glands, as well as from the tumor itself.
Abiraterone acetate is indicated for use in combination with prednisone for the treatment of men with metastatic castration-resistant prostate cancer who have already received prior chemotherapy containing docetaxel.
