In medicine, bisphosphonates are medications which "contain P-C-P bonds, where P stands for phosphonates or phosphonic acids. These compounds affect calcium metabolism. They inhibit ectopic calcification and slow down bone resorption and bone turnover. Technetium complexes of diphosphonates have been used successfully as bone scanning agents."[1]
Bisphosphonates are used to prevent fractures among patients with osteoporosis or low bone mass.
Examples of bisphosphonates include alendronate, risedronate, etidronate, ibandronate, pamidronate, and zoledronic acid.
Adverse effects
Atrial fibrillation may be caused by zoledronic acid.[2]
Osteonecrosis of the jaw was first reported in September, 2003; however, one publication suggested biphosphonates were causal[3] whereas the other study did not make this assertion as the patients were also taking other medications[4]. The following month, Novartis which is the manufacturer of Zometa, tried to refute the claim.[5] A series of 63 patients were reported in 2004 in which the author asserted that biphosphosphonates were causal.[6] A systematic review of published cases was reported in 2006.[7] In March, 2004. The Food and Drug Administration asked Novartis to revise the label for Aredia.[8]
