In large studies, women taking bisphosphonates for osteoporosis have had unusual fractures ("bisphosphonate fractures") in the femur (thigh bone) in the shaft (diaphysis or sub-trochanteric region) of the bone, rather than at the femoral neck, which is the most common site of fracture. However, these fractures are rare (12 in 14,195 women ...
Denosumab, sold under the brand names Prolia among others, is a human monoclonal antibody used for the treatment of osteoporosis, treatment-induced bone loss, metastases to bone, and giant cell tumor of bone. [11] [12] The most common side effects are joint and muscle pain in the arms or legs. [13]
They are usually prescribed for patients with osteoporosis or other metastatic bone diseases [clarification needed], such as Paget's disease, osteogenesis imperfecta and fibrous dysplasia. [28] [29] The two main types of anti-resorptive drugs are bisphosphonate and denosumab. These drugs help to decrease the risk of bone fracture and bone pain.
Several other drugs, which treat bone loss or osteoporosis, including Merck's Fosamax, Amgen's Xgeva and Evenity, already come with safety information that warn against prescribing the drug to ...
Different bisphosphonates have not been directly compared, therefore it is unknown if one is better than another. [122] Fracture risk reduction is between 25 and 70% depending on the bone involved. [122] There are concerns of atypical femoral fractures and osteonecrosis of the jaw with long-term use, but these risks are low.
Bisphosphonates are popular drugs for treatment of osteoporosis. [1] Clodronic acid is a bisphosphonate used as a drug to treat osteoporosis. In biochemistry and medicinal chemistry, phosphonate groups are used as stable bioisosteres for phosphate, such as in the antiviral nucleotide analog, Tenofovir, one of the cornerstones of anti-HIV therapy.
Alendronate, a common bisphosphonate drug, has a three carbon length side chain for example. [17] Risedronate has heterocyclic structure containing nitrogen. Heterocyclic nitrogen containing bisphosphonates have revealed better results in terms of activity compared to earlier bisphosphonates with nitrogen bound to carbon chain. Studies on ...
The Agency recommended that doctors who prescribe bisphosphonate-containing medicines should be aware that atypical fractures may occur rarely in the femur, especially after long-term use, and that doctors who are prescribing these medicines for the prevention or treatment of osteoporosis should regularly review the need for continued treatment ...
