Abiraterone Acetate

This page provides concise information on the drug abiraterone acetate, including its indications, dosage and administration guidelines, mechanism of action, associated brands with their strengths, as well as important warnings and common side effects.

Background and Date of Approval

Abiraterone acetate, in conjunction with prednisone, received approval from the U.S. FDA on April 28, 2011, for the treatment of patients with metastatic castration-resistant prostate cancer who have undergone prior chemotherapy containing docetaxel.

Mechanism of Action of Abiraterone Acetate

Prostate cancer arises from an overproduction of male hormones (androgens/testosterone). Androgens are generated by the testicles, adrenal glands, and metastatic tumor. Abiraterone acetate functions by disrupting and inhibiting the enzyme CYP17A1, a catalyst in androgen production. This inhibition decreases the quantity of androgens synthesized in the body.
