It is unknown whether the angiotensin receptor antagonist valsartan exerts a renoprotective effect on patients with type 2 diabetes and diabetic nephropathy independent of its hypotensive effects. Forty patients with type 2 diabetes participated in this study. All patients received valsartan 40 mg, a dose with no clinical effect on blood pressure levels. Blood pressure, urinary albumin excretion (UAE), and creatinine clearance were determined at baseline and at the end of the 6-month treatment period. Antihypertensive and/or antidiabetic drugs, including insulin, were permitted throughout the study. After 6 months of valsartan therapy, mean UAE decreased from 86.8±196 to 46.9±97 μg/min (n
