Zoledronic acid (brand name-Zometa) is an FDA approved treatment for bone diseases (such as due to multiple myeloma, Paget’s disease, osteoporosis etc) in patients who have cancer. It is not used in cancer chemotherapy, and it will not slow or stop the spread of cancer.
Zoledronic acid is in a class of medications called bisphosphonates. It works by slowing bone breakdown, increasing bone density (thickness), and decreasing the amount of calcium released from the bones into the blood.
