Daily administration of eldecalcitol (ED‐71), an active vitamin D analog, increases bone mineral density by suppressing RANKL expression in mouse trabecular bone

Eldecalcitol (ED-71) is a new vitamin D₃ derivative recently approved for the treatment of osteoporosis in Japan. Previous studies have shown that the daily administration of ED-71 increases bone mineral density (BMD) by suppressing bone resorption in various animal models. In this study, we examined how ED-71 suppresses bone resorption in vivo, by analyzing bone histomorphometry and ex vivo osteoclastogenesis assays. Daily administration of...
