Treatment of osteoporosis with parathyroid hormone: evidence and perspective

Parathyroid hormone (PTH) is a promising bone formation-stimulating agent, and the recent large-scale randomized controlled trial (RCT) revealed that parathyroid hormone increases and reduces lumbar bone mineral density and fracture risk, respectively, more potently than bisphosphonates. Moreover, PTH is also effective for male or glucocorticoid-induced osteoporosis. However, the recent studies showed that the co administration of PTH and bisphosphonate is not good. The further accumulation of evidence about the combined or subsequent therapy is expected.
