Abstract
Cardiovascular disease and renal complications raise the risk of death and morbidity in patients with type 2 diabetes (T2D). Sodium/glucose cotransporter-2 inhibitors (SGLT2i) are a novel class of glucose-lowering drug that increases urine glucose excretion while decreasing blood glucose levels in type 2 diabetes patients by inhibiting glucose reabsorption. In the present article, we review the discovery and development of SGLT2i as a new T2D treatment approach for T2D; thereafter, we consider different cell-based methods for the evaluation of SGLT2i. Finally, we provide evidences from both clinical and experimental studies which bring up the cardio-renal protective effects of SGLT2i. We performed a literature search using PubMed, Google Scholar, and Web of Science to identify publications on preclinical and clinical studies of cardiorenal protective action of SGLT2i and their suggested mechanisms. SGLT2i have shown good effects in the improvement of cardiovascular and renal complications independent of glucose lowering effects. Besides controlling blood glucose levels, SGLT2i were found to exhibit therapeutic benefits on the kidney and cardiovascular system by lowering diabetic glomerular hyperfiltration, blood pressure (BP), body weight, uric acid concentrations, lipid peroxidation, inflammation, etc. As a result of their distinct mode of action, SGLT2i have emerged as a promising treatment option for T2D and maybe T1D due to their increased urine excretion of glucose. It has been demonstrated that SGLT2i have considerable protective effects on diabetic nephropathy (DN) and cardiomyopathy in well-designed experimental and clinical investigations.
