Pamidronate is a medication belonging to a class of drugs called bisphosphonates. It is primarily used to treat conditions related to high levels of calcium in the blood, such as those caused by certain cancers. Pamidronate works by inhibiting the activity of cells that break down bone, helping to maintain bone density and strength. This drug is often administered intravenously in a clinical setting. In addition to managing hypercalcemia, Pamidronate is also used in the treatment of osteoporosis and Paget's disease of bone. Patients receiving this medication are monitored for potential side effects, including flu-like symptoms and gastrointestinal issues.
