Greater BMD after 1 year for ALN/D5600 compared to calcitriol treatment in osteoporosis .
Alendronate sodium/vitamin D3 combination tablet versus calcitriol for osteoporosis in Chinese postmenopausal women: a 6-month, randomized, open-label, active-comparator-controlled study with a 6-month extension
Osteoporos Int. 2015 Sep;26(9):2365-74.219 postmenopausal Chinese women with osteoporosis were randomized to receive one of two medications: a weekly dose of alendronate sodium with vitamin D3 (ALN/D5600) or a daily dose of calcitriol. The purpose of the study was to determine if ALN/D5600 provided greater benefits for bone mineral density and other measures of osteoporosis compared to calcitriol and to assess the safety of alendronate treatment. ALN/D5600 resulted in significantly greater increases in bone mineral density, serum 25(OH)D, and reductions in biochemical markers of bone turnover in comparison to calcitriol, at up to 1-year follow-up. ALN/D5600 also had a higher rate of drug-related adverse events, but the number of serious adverse events was similar between groups.
