Osteoporosis, a major worldwide health problem, affects 4 millionto 6 million women and 1 million to 2 million men in the UnitedStates. Even more people have decreased bone mass, which, inaddition to other risk factors, can be a major therapeutic challenge.1Fractures, the most important consequence of osteoporosis, areassociated with enormous costs and substantial morbidity andmortality. The prevention and treatment of this disease aretherefore of paramount importance. Since postmenopausal osteoporosisis characterized by bone resorption that exceeds bone formation,antiresorptive agents can help to restore skeletal balance byreducing bone turnover, primarily at the . . .
