1.8.3.0 Direct Renal Effects of Glucose-Lowering Medications
Some glucose-lowering medications also have effects on the kidney that are direct, i.e., not mediated through glycemia. For example, SGLT2 inhibitors reduce renal tubular glucose reabsorption, weight, systemic blood pressure, intraglomerular pressure, and albuminuria and slow GFR loss through mechanisms that appear independent of glycemia (18,40–43). Glucagon-like peptide 1 receptor agonists (GLP-1 RA) also have direct effects on the kidney and have been reported to improve renal outcomes compared with placebo (44-47). Renal effects should be considered when selecting antihyperglycemia agents (see Section 9 “Pharmacologic Approaches to Glycemic Treatment”).
