Practical Approach to Initiating SGLT2 Inhibitors in Type 2 Diabetes.

Sodium-glucose co-transporter 2 (SGLT2) inhibitors are an attractive novel therapeutic option for the treatment of type 2 diabetes. They block the reabsorption of filtered glucose in kidneys, mainly in proximal renal tubules, resulting in increased urinary glucose excretion and correction of the diabetes-related hyperglycemia. Beyond improving glucose control, SGLT2 inhibitors offer potential benefits by reducing body weight and blood pressure. On the basis of the efficacy demonstrated in clinical trials, SGLT2 inhibitors are recommended as second- or third-line agents for the management of patients with type 2 diabetes. Beneficial effects on kidney disease progression, cardiovascular and all-cause mortality, and hospitalization for heart failure have also been demonstrated with one SGLT2 inhibitor (empagliflozin). Potential adverse events resulting from their mechanism of action or related to concomitant therapies are reviewed. A treatment algorithm for the adjustment of concomitant therapies after initiating SGLT2 inhibitors is also proposed.
