Efficacy of risedronate with cholecalciferol on bone mineral density in Korean patients with osteoporosis
Abstract
UNLABELLED: The efficacy of once-weekly risedronate with and without cholecalciferol in bone mineral density (BMD) in Korean patients with osteoporosis was compared. After 12 months, both spine and hip BMD increased significantly in both groups, but there was no significant difference between two groups.
INTRODUCTION: This study investigated the efficacy and safety of once-weekly risedronate with and without cholecalciferol in BMD in Korean patients with osteoporosis.
METHODS: This was a prospective, 12-month, randomized, open-labeled, actively controlled trial involving 41 hospitals. A total of 841 subjects with osteoporosis were randomized to once-weekly risedronate (35 mg) and cholecalciferol (5600 IU) in a single pill (RSD+, n = 642) or once-weekly risedronate (35 mg) alone (RSD, n = 199). BMD was measured via dual-energy X-ray absorptiometry at the lumbar spine and hip, and the serum levels of 25-hydroxy vitamin D (25(OH) D), parathyroid hormone (PTH), and alkaline phosphatase (ALP) were assayed at baseline and after 12 months of treatment.
RESULTS: After 12 months, the lumbar spine, femoral neck, and total hip BMD increased significantly in both groups; there was no significant difference between two groups. Women in the RSD+ group exhibited significantly increased lumbar spine BMD, and subjects with previous fracture history in the RSD+ group had significantly increased total hip BMD compared with the RSD group. The serum 25(OH) D level increased significantly in the…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 841 participants or records.
