After the extraction of data from eligible studies, randomized controlled trials (RCTs) were assessed for quality and analyzed statistically. Standardized mean difference (SMD) and risk ratio (RR) with 95% CIs were used to evaluate efficacy and safety end-points. Sensitivity analyses and subgroup analyses based on intervention times were also performed.</p> <p><b>Results</b>: Five RCTs with 847 patients were included. Compared to metformin alone, ipragliflozin as an adjuvant to metformin reduced glycated hemoglobin (HbA1c) in 12 weeks and 24 weeks, respectively [12 w: SMD −0.30, 95% CI −0.51 to −0.10%, p = 0.004; 24 w: SMD −0.88, 95% CI −1.04 to −0.72%, p < 0.00001; Total: SMD −0.66, 95% CI −0.79 to −0.53%, p < 0.00001]. In addition, ipragliflozin as adjuvant therapy to metformin body weight (Total: SMD −1.47, 95% CI [−1.80,-1.14], p < 0.00001), waist circumference (Total: SMD −1.09, 95% CI [−1.62,-0.56], p < 0.00001), and blood pressure (SBP Total: SMD −3.36, 95% CI [−5.11.-1.61], p = 0.0002; DBP Total: SMD −2.18, 95% CI [−3.63,-0.74], p = 0.003). Compared to metformin alone, ipragliflozin as an adjuvant to metformin showed significant risks in the skin and subcutaneous tissue disorders and constipation.</p> <p><b>Conclusion:</b> Compared to metformin alone, ipragliflozin plus metformin significantly improved glycemic control, reduced body weight, and lowered blood pressure; however, further high-quality trials are required to determine their long-term efficacy and safety.</p> 2019-09-05 17:26:53 Ipragliflozin metformin type 2 diabetes mellitus SGLT2 inhibitor meta-analysis
