Bisphosphonates are widely used in the treatment of clinical disorders characterized by increased bone resorption, including osteoporosis, Paget's disease, and the skeletal complications of malignancy. The antiresorptive potency of the nitrogen-containing bisphosphonates on bone in vivo is now recognized to depend upon two key properties, namely mineral binding affinity and inhibitory activity ...
Adverse effects associated with the use of bisphosphonates are infrequent and consist of pyrexia, renal function impairment, and hypocalcemia. Bisphosphonates-associated osteonecrosis of the jaws is an uncommon but potentially serious complication of intravenous bisphosphonate therapy in cancer patients. The degree of risk for osteonecrosis in patients taking oral bisphosphonates, such as alend...
Introduction Bone metastases are a major cause of morbidity for patients with many types of cancer including multiple myeloma, breast cancer, prostate cancer, and other solid tumors. The clinical complications of bone metastases include pain, fracture, spinal cord compression, and hypercalcemia of malignancy. Although there are important differences in the biology of bone metastases from differ...
osteoporosis, characterized by low bone mass and microarchitectural deterioration of bone tissue leading to enlarged bone fragility and a consequent increase in fracture risk is a leading cause of morbidity and mortality in elderly people. the mortality rate in elderly persons with hip fracture approaches 20%. half of them will be disabled in the remained life. iranian multicenter osteoporosis ...
Bisphosphonates are powerful drugs. Their ability to reduce the risk of osteoporotic fractures has saved thousands of people from becoming a fracture patient. Osteoporosis is due to an imbalance in the maintenance remodeling of the skeleton. This remodeling is different from the repair processes following fracture or bone surgery. Because research on the use of bisphosphonates has mostly focuse...
abstract numerous clinical studies have shown bisphoshonates (bps) to be useful and cost-effective options for the fractures prevention and postmenopausal bone loss. the use of oral bisphoshonates is an established option for managment of osteoporosis in postmenopausal women, but many of them complaint from gastrointestinal side effect or frequently dosed oral regimens. to improve upon the subo...
We investigated three series of sulfonium bisphosphonates for their activity in inhibiting the growth of three human tumor cell lines. The first series consisted of 6 cyclic sulfonium bisphosphonates, the most active species having an (average) IC50 of 89 microM. The second consisted of 10 phenylalkyl and phenylalkoxy bisphosphonates, the most active species having an IC50 of 18 microM. The thi...
Although for many decades bisphosphonates were used for adult bone loss, bisphosphonate administration in pediatric patients is new and was initiated in the past 15-year. The indications for pediatric bisphosphonates was extended to childhood malignancies with bone involvement, after additional effects were unveiled for bisphosphonates with recent research. In this article we review childhood b...
