Historical perspectives on the clinical development of bisphosphonates in the treatment of bone diseases

Abstract

Bisphosphonates (formerly termed diphosphonates) were first synthesized in the late 1800s; however, their clinical use has been relatively recent. The bisphosphonates' affinity for hydroxyapatite crystal surface led Procter and Gamble to test these compounds in dental, then medical applications. With key input from university researchers, this led to the medical use of the first bisphosphonate, etidronate disodium in 1968 to treat a young patient with myositis ossificans progressiva. Further clinical research led to widespread medical application for the bisphosphonate class including use as a diagnostic in radionuclide bone imaging agents, treatment of osteoporosis, Paget's disease of bone, hypercalcemia of malignancy and metastatic bone disease. The historical development of bisphosphonates provides an excellent example of how observations and knowledge obtained at the basic science level were applied and successfully tested in the clinic. The end result of these efforts has provided health care professionals with diagnostic and therapeutic tools to improve the lives of patients.
