What is Abiraterone 500 mg?

Abiraterone 500 mg is designed for patients whose cancer has progressed despite other traditional hormone therapies.

Patients should use Abiraterone 500 mg under strict medical supervision to monitor dosages and evaluate treatment response. The combination of efficacy and safety profile makes it a trusted choice in modern prostate cancer care.
Uses of Abiraterone 500 mg
How Abiraterone 500 mg Works
Abiraterone 500 mg works by selectively inhibiting an enzyme called CYP17A1, which is critical for androgen production not only in the testes but also in the adrenal glands and prostate tumor tissue. Androgens such as testosterone play a central role in the development and progression of prostate cancer.
By blocking androgen synthesis, Abiraterone reduces the hormone supply that prostate cancer cells rely on for growth and survival. This hormone deprivation leads to a reduction in tumor activity and helps control the spread of the disease.
The medication is often combined with low-dose corticosteroids to prevent potential side effects related to mineralocorticoid excess caused by CYP17 inhibition, ensuring a balanced hormonal environment during therapy.
How to take Abiraterone 500 mg
Abiraterone 500 mg should be taken exactly as prescribed by your healthcare provider. It is usually administered orally once daily on an empty stomach—patients should avoid eating for at least two hours before and after taking the medication.
The tablet should be swallowed whole with water and must not be crushed or chewed. Adherence to the prescribed schedule is critical to maintain consistent drug levels in the body and achieve the best therapeutic outcome.
Regular medical follow-up is essential to monitor treatment response and adjust dosage if necessary. Patients should inform their physician about all other medications they are taking to prevent interactions.
