Background and aim: Beta-blockers have unfavorable effects on metabolic parameters in hypertensive treatment. New generation beta-blockers with vasodilatory capabilities are superior to traditional beta-blockers, but studies examining their effects on metabolic parameters are still lacking. This study aimed to compare the effects of 2 new generation beta-blockers, carvedilol and nebivolol, on insulin resistance (IR) and lipid profiles in patients with essential hypertension. Methods: This was a prospective, randomized, open-label, single-center clinical trial. A total of 80 patients were randomized into 2 groups: the carvedilol group (n = 40, 25 mg of carvedilol daily) and the nebivolol group (n = 40, 5 mg of nebivolol daily). Follow-up was performed for 4 months. Fasting plasma glucose, insulin levels, and the lipid profile (high-density lipoprotein [HDL], low-density lipoprotein [LDL], total cholesterol, triglyceride, apolipoprotein AI, and apolipoprotein B levels) were measured and IR was calculated by the homeostasis model assessment (HOMA) index. These variables were compared before and 4 months after treatment. Results: Blood pressure and heart rate were significantly and similarly reduced in the carvedilol and nebivolol groups after treatment compared to those before treatment (both P <.001). Serum glucose (P <.001), insulin (P <.01), HOMA-IR (P <.01), HDL (P <.001), LDL (P <.001), total cholesterol (P <.001), and apolipoprotein B (P <.05) levels decreased in a similar manner in the carvedilol and nebivolol groups after treatment compared to those before treatment. Serum triglyceride and apolipoprotein AI levels did not change after treatment with both drugs. Conclusion: New generation beta-blockers, carvedilol and nebivolol, efficiently and similarly decrease blood pressure. They have similar favorable effects on glucose, insulin, IR, and the lipid profile.
