The effectiveness of an angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker for the reduction in urinary protein excretion and renoprotection in proteinuric chronic kidney disease patients is well known, and coadministration of and sodium-glucose cotransporter inhibitor and the mineralocorticoid receptor blocker eplerenone has recently demonstrated an additive albuminuria-lowering effect in chronic kidney disease patients. This evidence concerns the gene NR3C2 and chronic kidney disease.
