Forbes, June 27, 2007 GALVESTON -- A new study has found a link between bisphosphonates -- drugs used to treat bone cancers, osteoporosis and other conditions -- and serious jawbone problems. Previous studies have found an association between the use of intravenous bisphosphonates and osteonecrosis of the jaw or facial bones. In osteonecrosis, poor blood supply leads to bone death and deterioration. Biphosphonates are used to fight cancer-related bone lesions, elevated levels of calcium in the blood, or reduced bone density. For the study, published in the June 26 online issue of the Journal of the National Cancer Institute, researchers from the University of Texas Medical Branch in Galveston identified more than 14,000 people with cancer who were treated with bisphosphonates (either pamidronate or zoledronic acid) and more than 28,000 patients who did not receive these medications.
