Summary
abiraterone

Abiraterone (Zytiga) is a medicine used with prednisone to treat prostate cancer that has spread. It works by lowering the amount of androgen your body makes.

What It Treats
abiraterone

It is also used for high-risk castration-sensitive prostate cancer. You will take this medicine with prednisone.

spironolactone (acne)

Spironolactone can treat heart failure by helping you live longer, managing swelling, and reducing hospital visits. It also treats high blood pressure, which lowers the risk of strokes and heart attacks. This medicine can also manage swelling caused by liver problems or a kidney problem called nephrotic syndrome when other treatments don't work well enough. It can also treat primary hyperaldosteronism, a condition where your body makes too much aldosterone.

How It Works
abiraterone

Abiraterone blocks an enzyme called CYP17, which your body needs to make androgens. Androgens can help prostate cancer grow. By blocking this enzyme, abiraterone lowers androgen levels and slows cancer growth.

spironolactone (acne)
