Guide to Abiraterone

Prostate Cancer

Abiraterone acetate is the generic name for the prescription drug, Zytiga. It is typically used in combination with prednisone or prednisolone in the treatment of patients with metastatic castration-resistant prostate cancer. It is a type of hormone therapy and is classified as an “adrenal inhibitor.” As an adrenal inhibitor, it helps interrupt the androgen-making process which can play a significant role in the treatment of prostate cancer. Lowering the androgen levels in prostate cancer cells is crucial in helping to shrink the cancer cells or cause them to grow more slowly.

In a clinical trial in patients with CRPC, a treatment combination of Abiraterone and prednisone showed to be helpful in prolonging patients’ overall survival rate when compared to a placebo. Some of the most common adverse reactions reported during clinical trials included: joint swelling, muscle discomfort, hot flush, urinary frequency, hypertension, nausea, high cholesterol, and cough.

How is Abiraterone Taken?

Abiraterone (Zytiga) is usually prescribed along with prednisone to patients who have received prior chemotherapy containing docetaxel. It must be taken on an empty stomach. No food should be consumed for at least one hour before the medication, or patients should wait two hours after a meal before taking it.

A dose of 1,000 mg is typically administered once daily, combined with 5mg of oral prednisone. The medication should be taken approximately the same time every day, and tablets should be swallowed whole with water. Abiraterone should be avoided by patients with severe hepatic impairment.

What Does Abiraterone Look Like?

250 mg Abiraterone acetate tablets are white to off-white in color, oval in shape, and stamped with AA250 on one side.

Is Abiraterone a Form of Chemotherapy?

Despite its use in helping to treat prostate cancer, Abiraterone is considered hormone therapy and is not a form of chemotherapy.

While Abiraterone is not a cure for prostate cancer, it can work as a treatment for the disease, helping to slow the growth of prostate cancer cells and keep it under control. It has been shown to help some patients live longer, while managing some of the symptoms related to the illness.

How Does Abiraterone Work?

Abiraterone works differently than other androgen inhibitors in the sense that it interferes with an enzyme found in testicular, adrenal, and prostatic tumor tissues, stopping androgen production at the three main production sites. This results in the decreased production of the male hormone testosterone, the hormone that can cause cancer cells to grow.
