Background: Liraglutide has been shown to improve glucose tolerance and lose weight in individuals with type 2 diabetes. To date, no meta-analysis of liraglutide???s safety and efficacy in individuals without diabetes has been conducted.Objectives: The aim of this study is to carry out a meta-analysis to assess the efficacy and safety of liraglutide in the obese, non-diabetic individuals.Methods: A literature review was performed to identify all published randomised control trials (RCT) of liraglutide for the treatment of obesity in non-diabetic individuals. The search included the following databases: EMBASE, MEDLINE and the Cochrane Controlled Trials Register.Results: We included five publications involving a total of 4,754 patients that compared liraglutide with placebo and found that liraglutide to be an effective and safe treatment for weight loss in individuals without diabetes. Primary efficacy end points: mean weight loss (MD = -5.52, 95% CI = -5.93 to -5.11, p<0.00001); lost more than 5% of body weight (OR = 5.46, 95% CI=3.57 to 8.34, p<0.00001) and key secondary efficacy end points: SBP decreased (the MD = -2.56, 95% CI = -3.28 to -1.84, p<0.00001). Safety assessments included the proportion of individuals who were withdrawn due to AE (OR = 2.85, 95% CI= 0.84 to 9.62, p=0.009), and nausea indicated that liraglutide was well tolerated. Conclusion: This systematic review and meta-analysis indicates that liraglutide to be an effective and safe treatment for weight loss in the obese, non-diabetic individuals.Keywords: liraglutide, weight loss, meta-analysis.
