What is the role of ACE inhibitors in diabetes?

These drugs can help people with diabetes reduce their risk of heart attack, stroke, and premature death. They may also delay the onset and progression of kidney disease. In addition, ACE inhibitors can help reduce other complications of diabetes, such as foot ulcers and eye damage (retinopathy). Retinopathy is the leading cause of blindness for people with diabetes. They can help prevent diabetic complications in people who do not have high blood pressure.

ACE inhibitors include the drugs benazepril (brand name Lotensin), captopril (>Capoten), enalapril (>Vasotec), fosinopril (>Monopril), lisinopril (>Prinivil or >Zestril), moexipril (>Univasc), quinapril (>Accupril), ramipril (>Altace), perindopril (>Aceon), and trandolapril (>Mavik).

People who take ACE inhibitors run a slightly increased risk of low blood sugar. Therefore, if you have diabetes, you should have your blood sugar levels closely monitored for the first few weeks after you start taking an ACE inhibitor, or after increasing the dosage.
