Hi. I'm a type 1 age 45 and have had diabetes for 20 years. I've been on Vasotec (enalapril maleate) for about 9 years now. I started at 10mg./day but now take 40 mg. I was originally put on it to "protect my kidneys"; my blood pressure was only a little high then. It apparently keeps the little capillaries in the kidney's open, since its a "vaso-dialater", I think it's called. The medicine has worked wonderfully for me, my bp is usually around 120/80.
