What are the effects of angiotensin converting enzyme inhibitors on diabetic nephropathy? 
Angiotensin converting enzyme inhibitors (ACEIs) have been found to have positive effects on diabetic nephropathy. Studies have suggested that ACEIs can improve renal function and reduce proteinuria in normotensive and type 2 diabetic patients with microalbuminuria. They have also been shown to delay the progression of nephropathy in normotensive type 1 diabetic patients with microalbuminuria, and to reduce cardiovascular and renal outcomes in type 2 diabetic patients with raised excretion of urinary albumin. Additionally, ACEIs have been found to have a stabilizing effect on plasma creatinine levels and proteinuria in normotensive type II diabetic patients.
