Abiraterone Acetate


Abiraterone Acetate is a CYP17 inhibitor indicated in combination with prednisone for the treatment of patients with

  • Metastatic castration-resistant prostate cancer (CRPC).
  • Metastatic high-risk castration-sensitive prostate cancer (CSPC).


Abiraterone is an orally active inhibitor of the steroidal enzyme CYP17A1 (17 alpha-hydroxylase/C17,20 lyase). It inhibits CYP17A1 in a selective and irreversible manner via covalent binding mechanism. CYP17A1 is an enzyme that catalyzes the biosynthesis of androgen and is highly expressed in testicular, adrenal, and prostatic tumor tissue. More specifically, abiraterone inhibits the conversion of 17-hydroxyprognenolone to dehydroepiandrosterone (DHEA) by the enzyme CYP17A1 to decrease serum levels of testosterone and other androgens.


Dosage & Administration

Metastatic castration-resistant prostate cancer: Abiraterone 1,000 mg orally once daily with prednisone 5 mg orally twice daily.

Metastatic castration-sensitive prostate cancer: Abiraterone 1,000 mg orally once daily with prednisone 5 mg orally once daily.

Patients receiving Abiraterone should also receive a gonadotropin-releasing hormone (GnRH) analog concurrently or should have had bilateral orchiectomy. Abiraterone must be taken on an empty stomach with water at least 1 hour before or 2 hours after a meal. Do not crush or chew tablets.

Dose Modification:

  • For patients with baseline moderate hepatic impairment (Child-Pugh Class B), reduce the Abiraterone starting dose to 250 mg once daily.
  • For patients who develop hepatotoxicity during treatment, hold Abiraterone until recovery. Retreatment may be initiated at a reduced dose. Abiraterone should be discontinued if patients develop severe hepatotoxicity.

CYP3A4 Inducers: Avoid concomitant strong CYP3A4 inducers during Abiraterone treatment. If a strong CYP3A4 inducer must be co-administered, increase the Abiraterone dosing frequency.

CYP2D6 Substrates: Avoid co-administration of Abiraterone with CYP2D6 substrates that have a narrow therapeutic index. If an alternative treatment cannot be used, exercise caution and consider a dose reduction of the concomitant CYP2D6 substrate.


Hypersensitivity to the Abiraterone acetate or to any of the excipients of Abiraterone.
