SGLT2 inhibition to address the unmet needs in diabetic nephropathy

Current treatment of diabetic nephropathy is effective; however, substantial gaps in care still remain and new therapies are urgently needed to reduce the global burden of the complication. Desirable properties of an “ideal” new drug should include primary prevention of microalbuminuria, additive/synergistic anti‐proteinuric effect in combination therapy with renin angiotensin system blockers, reduction of chronic kidney disease progression to lower the risk of end‐stage renal disease, and cardiovascular protection. Growing evidence suggests that sodium‐glucose cotransporter 2 inhibitors (SGLT2i) may fulfil many of these criteria and represent novel tools to cover the unmet needs in diabetic nephropathy care. However, the underlying mechanisms of SGLT2i renal benefits are still poorly understood and promising results from cardiovascular outcome trials with SGLT2i need confirmation in dedicated renal outcome trials.
