Arsenic Trioxide
Arsenic Trioxide is used to treat a type of blood cancer called acute promyelocytic leukaemia (APL). It may be used in combination with another medicine called tretinoin for patients with APL, or for patients whose APL has come back or has not responded to previous treatment with chemotherapy.
The exact way Arsenic Trioxide works is not completely understood. It is thought to work by causing cancer cells to break down and die. It also damages a specific abnormal protein found in APL cancer cells, helping to stop the cancer from growing.
