NameEtidronic acid
Groups approved
DescriptionEtidronic acid is a first generation bisphosphonate similar to [clodronic acid] and [tiludronic acid].[A203111] These drugs were developed to mimic the action of pyrophosphate, a regulator of calcification and decalcification.[A1923] Etidronate’s use has decreased over the years in favor of the third generation, nitrogen containing bisphosphonate [zoledronic acid], [ibandronic acid], [minodronic acid], and [risedronic acid].[A203111] Etidronic acid was granted FDA approval on 1 September 1977.[L13901]
