ABSTRACT
BACKGROUND/AIMS: Oxidative stress plays an important role in the pathogenesis and progression of diabetic complications and antagonists of renin-angiotensin system and amlodipine have been reported previously to reduce oxidative stress. In this study, we compared the changes in oxidative stress markers after valsartan and amlodipine treatment in type 2 diabetic patients with hypertension and compared the changes in metabolic parameters. METHODS: Type 2 diabetic subjects with hypertension 30 to 80 years of age who were not taking antihypertensive drugs were randomized into either valsartan (n = 33) or amlodipine (n = 35) groups and treated for 24 weeks. We measured serum nitrotyrosine levels as an oxidative stress marker. Metabolic parameters including serum glucose, insulin, lipid profile, and urine albumin and creatinine were also measured. RESULTS: After 24 weeks of valsartan or amlodipine treatment, systolic and diastolic blood pressure decreased, with no significant difference between the groups. Both groups showed a decrease in serum nitrotyrosine (7.74 ± 7.30 nmol/L vs. 3.95 ± 4.07 nmol/L in the valsartan group and 8.37 ± 8.75 nmol/L vs. 2.68 ± 2.23 nmol/L in the amlodipine group) with no significant difference between the groups. Other parameters including glucose, lipid profile, albumin-to-creatinine ratio, and homeostasis model assessment of insulin resistance showed no significant differences before and after treatment in either group. CONCLUSIONS: Valsartan and amlodipine reduced the oxidative stress marker in type 2 diabetic patients with hypertension.
