Denosumab (Prolia)
Denosumab (Prolia) is a biologic medication used to treat fragile bones, also known as osteoporosis, and prevent bone fractures. As a biologic drug, it is human-made and closely resembles naturally occurring antibodies in the body. In this case, it stops a molecule, called RANKL, which normally causes bone metabolism. By blocking RANKL, it helps to build and strengthen bones.
