Abiraterone acetate is a medication used primarily to treat advanced prostate cancer. It works by inhibiting the production of androgens, such as testosterone, which can fuel the growth of cancer cells. By lowering androgen levels, abiraterone acetate helps slow down the progression of the disease and can improve survival rates in patients. This drug is often prescribed in combination with prednisone, a corticosteroid that helps manage side effects and improve treatment effectiveness. Abiraterone acetate is typically administered as an oral tablet and is part of a broader treatment plan that may include other therapies, depending on the patient's condition.
