Abiraterone is a prescription medication used to treat prostate cancer that has spread to other parts of the body. It is an anti-androgen drug, meaning it blocks the effects of androgens, such as testosterone, which can help slow the growth of the cancer. Abiraterone is typically used in combination with prednisone. Common side effects of the drug include joint and muscle pain, fatigue, headache, high blood pressure, and diarrhea.
Abiraterone acetate, sold under the brand name Zytiga among others, is a medication used to treat prostate cancer. Here's a detailed breakdown of its characteristics:
Type of drug:
- Androgen synthesis inhibitor: Abiraterone acetate works by blocking the production of androgens, specifically testosterone, in the body. Androgens play a crucial role in the growth and development of prostate cancer cells.
Conditions treated:
- Metastatic castration-resistant prostate cancer (mCRPC): This is an advanced stage of prostate cancer where the cancer cells have spread to other parts of the body and are no longer responsive to castration (reduction of testosterone levels).
- Metastatic high-risk castration-sensitive prostate cancer (mCSPC): This is a type of prostate cancer that has a high risk of spreading to other parts of the body, even though testosterone levels have been reduced through castration.
Mechanism of action:
- Abiraterone acetate primarily targets the 17α-hydroxylase/17,20-lyase enzyme, which is essential for the production of testosterone in the testes, adrenal glands, and tumors. By inhibiting this enzyme, Abiraterone acetate decreases testosterone production and thereby hinders the growth and spread of prostate cancer cells.
Administration:
- Abiraterone acetate is administered orally as tablets, typically taken once daily with a meal containing fat to improve absorption.
Important to remember:
- Abiraterone acetate is always used in combination with a corticosteroid medication like prednisone to prevent a serious side effect called mineralocorticoid deficiency.
- It is not a cure for prostate cancer, but it can help slow the progression of the disease and improve symptoms like pain and difficulty urinating.
- Abiraterone acetate can cause side effects, including fatigue, high blood pressure, joint pain, hot flashes, and diarrhea. It's crucial to discuss the potential risks and benefits with your doctor before starting treatment.
