The result showed a dose of calcitriol 0.75 microgram/day for one month significantly decreased the level of PTH, bone marker for resorption and NMID osteocalcin 61.55, 69.92, 60.02 percent respectively (p=0.000). The other group which took calcitriol 0.5 microgram/day had little change to such markers. The active form of vitamin D benefits bone health by enhancing osteocalcin formation, in addition vitamin D has moderate antiresorption and suppression of PTH secretion.Mahidol UniversityMedicineConference PaperSCOPUS
