Systemic evaluation and Meta-analysis of Xianling Gubao capsule in treatment of primary osteoporosis in randomized controlled trials

Abstract

To evaluate the efficacy and safety of Xianling Gubao capsule in the treatment of osteoporosis (OP). Eight Chinese and English databases were retrieved (from establishment to February 2017), and clinical trials were screened according to the preset inclusion criteria and exclusion criteria. Then risk assessment tools were used for quality evaluation of the studies, and data extraction and analysis were conducted by using RevMan 5.3 software for Meta-analysis. A total of 1 895 articles were retrieved, and finally 54 studies were included. The total sample number was 5 030, including 2 543 cases in experimental group and 2 487 cases in control group. As compared with CT (routine therapy) intervention, Xianling Gubao capsules showed higher SOP efficiency and improved bone mineral density in patients with OP [MD=0.08, 95%CI (0.06, 0.10)]. As compared with control group, Xianling Gubao capsule+CT showed higher efficiency in PMOP and SOP, increased bone mineral density in OP patients [MD=0.04, 95%CI (0.03, 0.05)], POP patients [MD=0.08, 95%CI (0.05, 0.10)], and SOP patients [MD=0.06, 95%CI (0.05, 0.07)], relieved osteoporotic pain in OP patients [MD=-0.93,95%CI(-1.16, -0.70), increased alkaline phosphatase level in OP patients [MD=7.53, 95%CI (5.91, 9.14), blood calcium in OP patients [MD=0.03, 95%CI (0.01, 0.06)], and osteocalcin level in OP patients [MD=4.09, 95%CI (3.20, 4.98)], and increased serum phosphorus level in SOP patients [MD=0.03, 95%CI (0.00, 0.05)]. The main adverse reactions reported were liver injury and gastrointestinal symptoms. Xianling Gubao capsule alone or combined use with other medicines had better efficacy than western medicine alone in the treatment of osteoporosis. However, because of potential bias in the included studies, more high-quality randomized controlled trials would be needed to improve the level of evidence.
