The aim of this narrative review is to critically assess the renoprotective effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in managing albuminuria among patients with type 2 diabetes mellitus within the framework of personalized medicine. By integrating current evidence from clinical trials and meta-analyses, the review highlights how GLP-1RAs not only enhance glycemic control but also reduce blood pressure, induce weight loss, and mitigate inflammatory responses. While these given factors may vary according to individual patient profiles, they also collectively contribute to slowing the progression of diabetic kidney disease (DKD). Additionally, the discussion emphasizes the dual cardiovascular and renal benefits from these agents, underscoring their role in reducing albuminuria and preserving renal function. The review also identifies gaps in knowledge, suggesting future research directions for optimizing patient selection and treatment regimens to maximize therapeutic benefits.
