Activation of renin angiotensin system is implicated in insulin resistance. In mega trials, it has been suggested that angiotensin receptor blockers may be beneficial on insulin sensitivity in hypertensive patients. We conducted a multicenter, open-label, parallel-group trial to compare the effects of olmesartan and valsartan on insulin sensitivity and adiponectin levels in 206 hypertensive patients with diabetes mellitus or impaired glucose tolerance. Patients were randomly assigned to either olmesartan 20 mg/day or valsartan 80 mg/day treatment for 24 weeks. Blood pressure, fasting glucose, fasting insulin, glycosylated hemoglobin (HbA1c), homeostasis model assessment for insulin resistance (HOMA-IR), and serum adiponectin levels were measured.
