[Improvement of QOL in osteoporotic patients by calcitonin treatment].

Quality of life (QOL) is impaired in patients with osteoporosis, to which bodily pain greatly contributes. The presence of vertebral fractures detrimentally affects the patients' QOL in a dose-dependent manner. Calcitonin, with its potent analgesic action, markedly improves the various aspects of patients' QOL. Efficacy for the treatment of osteoporosis should be evaluated in terms of QOL also, in addition to the increase in bone mineral density and fracture prevention.
