As a bisphosphonate, tiludronate keeps the patient’s bones strong by increasing bone density and preventing bone breakdown.


Tiludronate is used for treating Paget’s disease, which is a condition that makes the bones soft, weak, painful and easily deformed or broken. It works by slowing down bone breakdown and increasing the density of bones, making them stronger and less likely to break. Tiludronate also reduces the bone pain that comes with this condition. It belongs to a class of medications known as bisphosphonates.
