Clodronate belongs to a group of drugs called bisphosphonates. It can be used to treat:
- high levels of calcium in the blood caused by cancer that has spread to the bones
- bone weakness or pain caused by myeloma or breast cancer that has spread to the bones.
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.
Clodronate can be given with other cancer treatments.
