1. Why am I using ARX-SUNITINIB?

ARX-SUNITINIB contains the active ingredient sunitinib. ARX-SUNITINIB is an indolinone derivative and tyrosine kinase inhibitor with potential antineoplastic activity. It interferes with the growth of cancer cells, which are eventually destroyed.

ARX-SUNITINIB is used for treatment of

  • advanced renal cell carcinoma (RCC), a type of renal cancer
  • gastrointestinal stromal tumour (GIST) GIST is a cancer of the stomach and bowels. It is caused by the uncontrolled growth of cells in the wall of the stomach or bowel. ARX-SUNITINIB slows down the growth of these cells.
  • pancreatic neuroendocrine tumours. This is a rare cancer in the cells of the pancreas that release hormones.

Ask your doctor if you have any questions about why ARX-SUNITINIB has been prescribed for you.

Your doctor may have prescribed it for another purpose.

ARX-SUNITINIB is only available with a doctor’s prescription. It is not addictive.
