Comparative effects of enarapril versus losartan on the prevention of diabetic nephropathy in type 2 diabetes patients with microalbuminuria

A prospective randomized open-labeled study was performed to compare the renoprotective effects of enarapril and losartan on the development of microalbuminuria in type 2 diabetic patients with hypertension. Diabetic patients who have hypertension and microalbuminuria at base line (n=19) were recruited. Enarapril (n=11) or losartan (n=8) was randomly chosen by envelope methods and was prescribed for one year. At the end of this study, the blood pressure of patients in these two groups decreased significantly. Urine albumin-creatinine ratio (U-ACR) also decreased in these two groups, however, U-ACR of enarapril group was not significantly different from that of losartan group at any time of this study. Body mass index, HbA1c, blood pressure, and serum lipid profiles were not significantly different between the two groups. From these results, we conclude that the effects of enarapril and losartan on the development of microalbuminuria in type 2 diabetic patients along with hypertension seem to be equivalent in terms of clinical renoprotection.
