Effects of angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, and their combination on microalbuminuria in normotensive patients with type 2 diabetes.

The goal of this study was to compare the effects of lisinopril, losartan, and their combination on microalbuminuria in normotensive patients with type 2 diabetes mellitus. Patients were randomly assigned to 3 groups: group 1 (n=9), group 2 (n=9), and group 3 (n=8) received 10 mg lisinopril, 50 mg losartan, and 10 mg lisinopril plus 50 mg losartan, respectively, each day. For 12 mo, the 24-h urine albumin excretion rate was assessed at 3-mo intervals. At study completion, the urine albumin excretion rate had been reduced significantly in each group (P=.001); however, no significant differences were noted among groups (P=.587). Investigators in the present study have concluded that lisinopril, losartan, and their combination have similar effects on microalbuminuria in normotensive patients with type 2 diabetes mellitus, and that combination therapy does not provide additional benefit.
