Background: Angiotensin II regulates the production of adipokines. The objective was to study the effect of treatment with irbesartan versus olmesartan in obese hypertensive women.

Subjects: A sample of 34 obese hypertensive women was analyzed in a prospective way with a randomized trial. Patients were randomized to irbesartan (300 mg/day) or olmesartan (40 mg/day) for 3 months. Weight, body mass index, blood pressure, basal glucose, insulin, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, HOMA and visfatin were determined at basal time and after 3 months of treatment.

Results: Thirty four patients gave informed consent and were enrolled in the study. A significative decrease in systolic and diastolic blood pressures was reached without changes in weight.

Patients treated with olmesartan had a significative decrease of total cholesterol, LDL cholesterol, insulin, HOMA and visfatin levels. Decrease in total cholesterol and LDL cholesterol was similar with both angiotensin receptor blockers. Decrease in insulin (2.28±2.77 vs 0.66±4.4 mUI/L: p Conclusion: The administration of olmesartan improved blood pressure, insulin, HOMA, visfatin and lipid profile in hypertensive obese women. Irbesartan improved blood pressure and lipid levels.
