Summary

This study will evaluate whether the once weekly administration of the combination tablet alendronate/vitamin D3 (FOSAMAX PLUS) will increase lumbar spine bone mineral density (BMD) more than the daily use of calcitriol.

Detailed Description

This was a 6-month, randomized, open-label, active-comparator controlled, parallel-group study with a 6-month extension to evaluate the safety and efficacy of alendronate sodium 70 mg plus vitamin D3 5600 IU combination tablets versus calcitriol in the treatment of osteoporosis in postmenopausal women in China. Participants were randomly assigned to receive alendronate 70 mg plus vitamin D3 5600 IU combination tablet once weekly orally or calcitriol 0.25 μg daily orally.
