Efficacy and safety of sodium-glucose cotransporter 2 inhibitors as add-on to metformin and sulfonylurea treatment for the management of type 2 diabetes: a meta-analysis
Abstract
This study evaluates the efficacy and safety of sodium-glucose cotransporter 2 (SGLT2) inhibitors as add-on to metformin and sulfonylurea treatment for type 2 diabetes management. The literature search was conducted in electronic databases and meta-analyses of mean differences in the changes from baseline in selected disease endpoints (efficacy endpoints) or odds ratios (for safety endpoints) were performed to compare outcomes between SGLT2 inhibitor- and placebo-/comparator-treatments. Seven studies (5,143 patients; age 56.75 years [95% CI: 56.19, 57.37]; body mass index 29.53 kg/m2 [28.23, 30.83]; and 51.87% [50.46, 53.57] males) were included. Compared to placebo, SGLT2 inhibitors significantly (p < 0.00001) reduced glycated hemoglobin (HbA1c; –0.79% [95% CI: –0.90, –0.68]), fasting plasma glucose (FPG; –1.73 mmol/L [–1.86, –1.60]) and body weight (–1.85 kg [–2.11, –1.59]) after 52–78 weeks of treatment. There were no significant differences in reduction of either HbA1c, FPG or body weight between 18–24 weeks and after 52–76 weeks of treatment. Treatment with SGLT2 inhibitors as add-on to metformin and sulfonylurea was also associated with significant reductions in blood pressure and triglycerides and increase in high-density lipoprotein-cholesterol. Incidence of hypoglycemia was significantly higher, but incidence of hyperglycemia was significantly lower in SGLT2 inhibitor group. Overall, drug-related adverse events were more common in SGLT2 group mainly due to higher…
