Abiraterone (Zytiga®)

Abiraterone

Brand Name: Zytiga®

Abiraterone is used in the treatment of prostate cancer.

Abiraterone is a type of hormone therapy, though it works a bit differently than other hormone treatments for prostate cancer. Specifically, this drug is known as an androgen biosynthesis inhibitor. The male hormone testosterone may stimulate the growth of prostate cancer, and therefore preventing the production of testosterone can slow or stop the growth of cancer. The majority of testosterone is made in the testes, but some is also produced in other tissues and in tumor cells. An enzyme called cytochrome P17 (CYP17) is essential to the production of testosterone. Abiraterone works by blocking CYP17, which in turn stops the testes and other tissues in the body from making testosterone.

This medication is given as a tablet taken by mouth. Abiraterone should be taken on an empty stomach about one or two hours before eating. Usually, this drug is taken once a day, and should be taken at around the same time each day. The tablets should be swallowed whole, and should not be split, chewed, or crushed. The exact dose and schedule of abiraterone depends on the condition being treated, how well the cancer is responding, and several other factors. Your doctor will determine the best regimen for you.

Abiraterone side effects

To prevent problematic interactions between abiraterone and other drugs, be sure to tell your doctor if you are allergic to any medications, and what other medications and supplements you are currently taking. You should also inform your doctor if you have or ever had liver tumor, liver disease, kidney disease, pituitary gland problems, high blood pressure, irregular heartbeat, low levels of potassium in your blood, or if you are experiencing unusually high levels of stress.

This drug is for use in men only. Men taking this drug must use a condom during sex with a pregnant woman during treatment and for 1 week afterwards. If you are having sex with someone who may become pregnant, you must use a condom and one other form of birth control during treatment and for 1 week afterwards.
