Efficacy and safety of empagliflozin for type 2 diabetes: a systematic review and meta-analysis
Abstract
AIM: To assess the efficacy and safety of the novel sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin compared with placebo or other antidiabetic agents in patients with type 2 diabetes. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials. We searched Medline, Embase and the Cochrane Library through December 2013 and grey literature. Two reviewers working independently extracted relevant data and carried out risk-of-bias assessments. We synthesized results using random-effects models and computed weighted mean differences (WMDs) and odds ratios (ORs). RESULTS: We included 10 studies with 6203 participants. Compared with placebo, mean changes in haemoglobin A1c were -0.62% [95% confidence interval (CI) -0.68 to -0.57%] for empagliflozin 10 mg and -0.66% (-0.76 to -0.57%) for empagliflozin 25 mg. Empagliflozin 25 mg daily had glycaemic efficacy similar to metformin or sitagliptin (WMD -0.11%; 95% CI -0.25 to 0.03%), without increasing risk for hypoglycaemia. It was also associated with body weight loss (WMD -1.84; 95% CI -2.30 to -1.38 kg vs. placebo) and had a favourable effect on blood pressure. Incidence of hypoglycaemia with empagliflozin was similar to placebo (OR 1.10; 95% CI 0.87 to 1.39); nevertheless we noted an increased risk for genital tract infections (OR 3.31; 95% CI 1.55 to 7.09). Findings were similar for the 10-mg dosing regimen. CONCLUSIONS: Empagliflozin effectively lowers blood glucose and provides…
