We suggest that SGLT2 inhibitors provide renal protection by modifying predisposing factors in the development of CKD, specifically albuminuria and GFR decrease. Other beneficial effects of these agents on blood pressure and sympathetic nerve activity might be considered as a possible mechanism for improving renal hemodynamics.
