  The Effects of Parathyroid Hormone and Alendronate Alone or in Combination in Postmenopausal Osteoporosis - New England Journal of Medicine
Save This Article To My Filing Cabinet Email This Article Conclusion: There was no evidence of synergy between parathyroid hormone and alendronate. Changes in the volumetric density of trabecular bone, the cortical volume at the hip, and levels of markers of bone turnover suggest that the concurrent use of alendronate may reduce the anabolic effects of parathyroid hormone. Longer-term studies of fractures are needed to determine whether and how antiresorptive drugs can be optimally used in conjunction with parathyroid hormone therapy...
  The Effects of Parathyroid Hormone, Alendronate, or Both in Men with Osteoporosis - New England Journal of Medicine
Save This Article To My Filing Cabinet Email This Article Conclusion: Alendronate impairs the ability of parathyroid hormone to increase the bone mineral density at the lumbar spine and the femoral neck in men.
