[Converting enzyme inhibitors in diabetes]

ACE inhibitors are used on a large scale basis in hypertensive diabetics, while the association between diabetes and hypertension is frequent and harmful. This is due to their excellent tolerance and efficacity. No specific advantage has been reported in their use regarding tolerance, i.e., they may not alter insulin sensitivity consistently. Conversely, ACE inhibitors may offer the specific advantage of protecting kidney function against diabetic microangiopathy, since their effects on glomerular haemodynamics seem independent from their hypotensive effect.
