The patients received teriparatide 20 µg daily by subcutaneous injection, for a maximum of 24 months. Safety and effectiveness analyses were based on data from 1,847 patients who were predominantly female (92.6%) with a mean age of 75.4 years. A total of 157 adverse drug reactions (ADRs) were reported in 140 (7.58%) patients; the most common ADRs were hyperuricemia, nausea, and dizziness. Only six (0.32%) patients reported serious ADRs, the most common being nausea (two patients; 0.1%). Persistence with teriparatide treatment was 60.8% and 39.1% at 18 and 24 months, respectively. There were significant increases in biomarkers for bone formation (procollagen type I N-terminal propeptide and bone-specific alkaline phosphatase) and bone resorption (collagen type I cross-linked C telopeptide and tartrate-resistant acid phosphatase 5b) throughout the study. These were accompanied by significant increases in bone mineral density and low incidences of new vertebral and nonvertebral fractures. Patient-reported measurements for health-related quality of life revealed significant improvements from baseline in back pain and overall health-related quality of life (Short Form-8™ health survey). The results of this 24-month postmarketing surveillance study imply that teriparatide has a favorable safety profile and is effective in the treatment of patients with osteoporosis at high risk of fracture in Japan. Teriparatide may also be a useful treatment for osteoporosis in other societies with aging populations. Keywords: parathyroid hormone, bone biomarkers, bone mineral density, quality of life, safety
