1. What is Abiraterone Synthon and what is it used for
Abiraterone Synthon is a medicine that contains abiraterone acetate. It is used in adult men to treat prostate cancer that has spread to other parts of the body. Abiraterone Synthon works by blocking the production of testosterone in the body; this can slow down the growth of prostate cancer.
When Abiraterone Synthon is used at an early stage of the disease that responds to hormonal therapy, it is given together with therapy that reduces testosterone levels (androgen suppression therapy).
During treatment with this medicine, your doctor will also prescribe another medicine called prednisone or prednisolone. This is to reduce the risk of high blood pressure, fluid retention, or low potassium levels in the blood.
2. Important information before taking Abiraterone Synthon
When not to take Abiraterone Synthon:
- in women, especially during pregnancy. Abiraterone Synthon is only used in men;
- in combination with the medicine Ra-223 (used to treat prostate cancer).
Do not take this medicine if any of the above situations apply to you. If you are unsure, consult your doctor or pharmacist before taking this medicine.
Warnings and precautions
Before starting treatment with this medicine, discuss it with your doctor or pharmacist:
- the need to take this medicine with prednisone or prednisolone;

Tell your doctor if you have any heart or blood vessel disorders, including heart rhythm disturbances (arrhythmia), or if you are taking medicines for these conditions.
Tell your doctor if you have yellowing of the skin or eyes, dark urine, severe nausea or vomiting, which may be signs of liver function disorders. Rarely, acute liver failure may occur, which can be life-threatening.
There may be a decrease in the number of red blood cells, decreased sex drive, muscle weakness, and (or) muscle pain.
Abiraterone Synthon should not be taken in combination with Ra-223 due to the possible increased risk of bone fractures or death.
