Introduction: Liraglutide is a glucagon-like peptide-1 receptor agonist (GLP-1 receptor agonist), also known as incretin mimetics. This is the new approach for management of weight among diabetic patients along with glycemic controls. The study aims to explore the efficacy of Liraglutide on weight (body mass index) and glycemic control (HbA1C) among adult patients with type 2 diabetes mellitus in primary care center. Methods: Retrospective chart review of 149 adult patients with type II diabetic taking Liraglutide as a monotharepy for 6 months and more were included in the study. Analysis was done in SPSS version 22. Results: Total 149 chart reviews were done. The mean age of participants were 55.52 (SD: 8.167). Of total 58.4% were female and 70% were on insulin. Paired sample statistics reported that pre- and post-change in BMI and weight was significantly different with P value < 0.001. However pre- and post-change in the value of HBA1c was not significantly different with P value 0.561. Conclusion: Through this retrospective study we can conclude that Liraglutide has important effect on weight loss and reduction in BMI. However, further longitudinal studies with large sample size and multi-center randomized controlled trials are needed to generalize the effectiveness of Liraglutide among Saudi population.
