Controversies in Osteoporosis Management

Women who have significant bone loss or a new fracture on monotherapy are considered for combination therapy. Combination therapies increase bone density more than monotherapy by targeting different parts of the osteoclast pathway.

In early postmenopausal women who are symptomatic, the use of combination antiresorptives should include hormone therapy with a bisphosphonate or with bazodoxifene. In women who initially receive a weaker antiresorptive such as the SERM raloxifene, a combination with bisphosphonates and calcium supplementation is necessary to prevent bone loss. In older women over 65 years of age who often have impaired calcium absorption, the combination of calcitriol with bisphosphonates has been shown to increase bone density more than monotherapy.
