    Abstract:
    An open, comparative, cross-over 8-week trial of beta-blockers nebivolol and metoprolol in 30 patients with arterial hypertension (AH) studied the office, ambulatory blood pressure and heart rate levels, endothelium-dependent vasorelaxation, endothelial NOS and NO production. It was found that nebivolol activated the system eNOS-NO and improved vasomotor parameters of the endothelium. Metoprolol failed to activate enzyme eNOS activity and NO production to the same level and did not improve the endothelial vasomotor function. The antihypertensive activity of nebivolol was higher than that of metoprolol. Thus, nebivolol can be used in patients with AH and cardiovascular risk factors to correct endothelial dysfunction.
