Zoledronic acid belongs to a group of drugs called bisphosphonates. It can be used to treat:
- a raised calcium level in the blood caused by cancer that has spread to the bones
- bone weakness or pain caused by myeloma or by breast cancer that has spread to the bones.
- to help prevent cancer spreading to the bones in women who have been treated for breast cancer and are post-menopausal.
Cancer that has spread to the bones is called secondary bone cancer. It happens when cells from the original (primary) cancer spread to form a new tumour (secondary cancer or metastasis) in the bone.
Myeloma is a cancer of a type of blood cell called plasma cells. The abnormal plasma cells build up inside bones causing pain and weakness.
Zoledronic acid can be given alongside other cancer treatments.
