The ideal choice and duration of antiresorptive therapy are not yet defined, however. In the Comparison of Alendronate or Raloxifene following Denosumab (CARD) study, we demonstrated that 12 months of alendronate was better able to maintain the bone mineral density (BMD) gains achieved with 12 months of denosumab versus 12 months of raloxifene.
