Zoledronic acid is a medication used primarily to treat conditions related to bone health, such as osteoporosis and certain types of cancer. It belongs to a class of drugs known as bisphosphonates, which work by slowing down the process of bone loss. This helps to strengthen bones and reduce the risk of fractures. The drug is typically administered through an intravenous infusion, usually once a year for osteoporosis or more frequently for cancer-related conditions. Patients receiving zoledronic acid may experience side effects, including flu-like symptoms, but it is generally well-tolerated and effective in improving bone density.
