Multicenter, double-blind randomized study conducted in six Spanish centers. We enrolled outpatients between the ages of 40 and 65 years with mild or moderate essential hypertension (systolic blood pressure, SBP ≥ 140 mmHg to ≤ 179 mmHg and diastolic blood pressure, DBP ≥ 90 mmHg to ≤ 109 mmHg after a 2-week run-in placebo period). Patients received nebivolol 5 mg or atenolol 50 mg once daily. At week 3, atenolol could be titrated up to 100 mg qd for non-responders. Additionally, patients not achieving normal blood pressure after 6 weeks could be treated with 25 mg hydrochlorothiazide. Follow-up visits were at 3, 6 and 10 weeks.

Nebivolol hydrochloride (R067555), is a new antihypertensive drug. Aromatic and alicyclic hydroxylation at the benzopyran ring systems of nebivolol are important metabolic pathways. Generally, NMR is used to unambiguously assign the sites of hydroxylation. Because of the low dose rates and the extensive metabolism of nebivolol in the different species, NMR identification is not always possible, and therefore another spectroscopic technique was searched for to address this problem. UV-chromophore absorption is affected by the kind and arrangement of adjacent atoms and groups (auxochromes). The effect of these auxochromes (e.g. -NH2, -NR2, -SH, -OH, -OR and halogens) can be strongly influenced by the pH. This paper proves that HPLC at high pH combined with on-line diode-array detection is an excellent technique for the location of the hydroxyl functions in hydroxylated metabolites of nebivolol. With this technique it is possible to differentiate between glucuronidation at the automatic and aliphatic or alicyclic hydroxyl functions.

In hypertensive kidney transplant recipients, the effects of nebivolol vs metoprolol on nitric oxide (NO) blood level, estimated glomerular filtration rate (eGFR), and blood pressure (BP) have not been previously reported. In a 12-month prospective, randomized, open-label, active-comparator trial, hypertensive kidney transplant recipients were treated with nebivolol (n=15) or metoprolol (n=15). Twenty-nine patients (nebivolol [n=14], metoprolol [n=15]) completed the trial. The primary endpoint was change in blood NO level after 12 months of treatment. Secondary endpoints were changes in eGFR, BP, and number of antihypertensive drug classes used. After 12 months of treatment, least squares mean change in plasma NO level in the nebivolol kidney transplant recipient group younger than 50 years was higher by 68.19% (99.17% confidence interval [CI], 13.02-123.36), 69.54% (99.17% CI, 12.71-126.37), and 66.80% (99.17% CI, 12.95-120.64) compared with the metoprolol group younger than 50 years, the metoprolol group 50 years and older, and the nebivolol group 50 years and older, respectively. The baseline to month 12 change in mean arterial BP, eGFR, and number of antihypertensive drug classes used was not significantly different between the treatment groups. In hypertensive kidney transplant recipients, nebivolol use in patients younger than 50 years increased blood NO.

Until recently elevated blood pressure was considered as a hemodynamic entity representing an increase in workload for the heart and the arterial tree. Control of hypertension meant hemodynamic unloading, through inhibition of vasoconstrictor pathways, principally renin-angiotensin system and sympathetic system. In recent years however a new pharmacological approach has evolved as a result of (i) the dissociation of endothelial dysfunction and vascular pathology from increased blood pressure; (ii) the recognition that endothelial dysfunction regards not only the vascular reactivity, but also promotes atherosclerosis and thrombosis; and (iii) an improved understanding of the complexity of local-tissue renin angiotensin system and of the vasodilatory and cytoprotective role of natriuretic peptides. This has led to a reconsideration of existing medicines in terms of specification on endothelial function, more rationalized application of drugs and search for new compounds targeting both vasodilatory and anti-proliferative pathways. Examples include beta1-adrenergic antagonists, such as Nebivolol and Carvedilol, and vasopeptidase inhibitors, such as Omapatrilat, that inhibit simultaneously the angiotensin converting enzyme and neutral endopeptidase. Furthermore the identification of genetic polymorphisms in the effectors involved in the pathophysiology of hypertension or in the response to anti-hypertensive drugs, such as the p22phox subunit of NADPH oxidase, alpha-adducin or adrenergic receptors, has promoted the prospective of both better understanding of hypertension and individualized strategies for its treatment.

The beta-adrenergic receptor blockers play an important role in the management of cardiovascular disease, including hypertension and chronic heart failure. However, concerns regarding safety and tolerability with currently available agents can limit their use. The beta-blockers vary with regard to several pharmacologic properties, including beta1/beta2 selectivity, intrinsic sympathomimetic activity, and, with the newest beta-blockers, vasodilation. These pharmacologic differences may result in clinically important differences in tolerability and hemodynamic properties. Nebivolol is a novel beta-blocker with both a greater degree of selectivity for beta1-adrenergic receptors than other agents in this class and an ability to stimulate endothelial nitric oxide production, leading to vasodilation and other potential clinical effects. Published randomized, controlled, multicenter studies with nebivolol have shown that once-daily treatment significantly reduces systolic and diastolic blood pressure in patients with mild-to-moderate hypertension, compared with placebo, in a dose-dependent manner, and is well tolerated, with an adverse event profile similar to that of placebo. When compared with other beta-blockers as well as with other antihypertensive classes of agents in head-to-head trials, nebivolol demonstrated similar antihypertensive efficacy and a lower incidence of adverse events. Nebivolol has also been shown to significantly reduce morbidity and mortality in a large population of elderly patients with chronic heart failure, independent of left ventricular ejection fraction. Nebivolol is currently available in Europe for the management of hypertension and is expected to be available soon in the United States.

We conclude that 24-hour ambulatory hemodynamic monitoring is feasible in clinical trials. The rate-slowing effects of nebivolol (both N and V/N) cause lower ambulatory cardiac oxygen consumption compared to V alone but at the same time, N and V/N cause an increase in stroke load. Absolute and relative heart rate variability is higher with V than N or V/N. These results are driven primarily by the effects in blacks.(Figure is included in full-text article.).

After pretreatment with paroxetine, the exposure to nebivolol was increased by 6·1-fold for the parent drug and 5·7-fold for the hydroxylated active metabolite. Paroxetine influenced nebivolol pharmacokinetics in healthy volunteers, but it did not have a significant effect on nebivolol pharmacodynamic parameters measured at rest, although the clinical relevance of this drug interaction needs further investigation.

Patients with CSF had higher body mass index (26.5 ± 3.3 vs. 23.8 ± 2.8, p < 0.001), mitral inflow isovolumetric relaxation time (IVRT) (114.9 ± 18.0 vs. 95.0 ± 22.0 msec, p < 0.001) and lower left ventricular ejection fraction (LVEF) (63.5 ± 3.1% vs. 65.4 ± 2.2, p = 0.009), HDL-cholesterol (39.4 ± 8.5 vs. 45.8 ± 7.7 mg/dL, p = 0.003) and brachial flow-mediated dilatation (FMD) (6.1 ± 3.9% vs. 17.6 ± 4.5%, p < 0.001). There were significant correlations between FMD and the presence of CSF (r = 0.800, p < 0.001) and HDL-cholesterol (r = 0.349, p = 0.003). Among Patients with CSF, although pretreatment mean FMD values were similar (6.1 ± 4.3% vs. 6.0 ± ,6%, p = 0.917) compared to aspirin alone group, posttreatment FMD was significantly higher in patients treated with aspirin plus nebivolol (6.0 ± 3.5% vs. 8.0 ± 2.9%, p = 0.047). Treatment with nebivolol was associated with a significant increase in FMD (6.0 ± 3.6 to 8.0 ± 2.9 %, p = 0.030) whereas treatment with aspirin alone was not.

159 patients undergoing coronary angiography (CAG) who had at least one risk factor for CIN were divided into nebivolol (+) and (-) groups. CIN was defined as a rise in sCr of 0.5mg/dl or a 25% increase from the baseline value. Serum Cr, glomerular filtration rate (eGFR) and NGAL levels were assessed before and 48 h after CAG. Mehran risk scores were calculated for both groups.
The present study was to assess whether nebivolol could activate beta(3)-adrenergic receptors (ARs) in the human heart.
These data suggest a new mechanism of action of nebivolol that may explain in part the reported NO activity.

The pharmacokinetics of nebivolol is enantioselective, with a greater plasma proportion of l-nebivolol. CKD increased the area under the concentration-time curve (AUC) of l-nebivolol (6.83 ng.h ml(-1) vs. 9.94 ng.h ml(-1) ) and d-nebivolol (4.15 ng.h ml(-1) vs. 7.30 ng.h ml(-1) ) when compared with the control group. However, the AUC values of l-nebivolol (6.41 ng.h ml(-1) ) and d-nebivolol (4.95 ng.h ml(-1) ) did not differ between the haemodialysis and control groups. The administration of a single dose of 10 mg nebivolol did not alter the heart rate variation induced by isometric exercise in the investigated patients.

Nebivolol administration attenuated cerebral vasospasm both by increasing NO levels and by decreasing oxidative stress. Our study also demonstrated that nebivolol administration reverses SAH created imbalance between SOD and GSH-Px by increasing GSH-Px activity relative to SOD.
Inflammation reduces pharmacological response to β1-blockers by down-regulating the target receptor protein. This may contribute to the sub-optimal response to pharmacotherapy with β-blockers. Nebivolol is a third generation β-adrenoceptor (AR) blocker with high selectivity for blocking β1 and β3-agonistic properties. We studied whether response to nebivolol is also reduced by inflammation. Male Sprague-Dawley rats (Inflamed; Mycobacterium butyricum induced) and Control (healthy) were orally administered single doses of 2 mg/kg nebivolol (n=5) or 25 mg/kg propranolol (positive control, n=7-8); ECG recorded for PR and RR interval measurements; serial blood samples were collected for pharmacokinetic assessment. Subsequently, the myocardial β1, β2 and β3-AR levels were measured in homogenized hearts. For propranolol, inflammation resulted in increased concentration but reduced response and down-regulation of β1- AR. The action and disposition of nebivolol were, however, unaffected by inflammation despite the reduced β1-AR levels. The levels of β2 and β3-AR were unaffected by inflammation. The consistency of response to nebivolol despite inflammation may be due to the predominance of contribution of β2 and β3-AR. The lack of an inhibitory effect of inflammation on the clearance of nebivolol is suggestive of mechanisms other than an efficient hepatic metabolism for its low bioavailability. If extrapolated to human, nebivolol may be a more effective cardiovascular drug when inflammatory conditions are present.

Despite nebivolol and atenolol having the same blood-pressure-decreasing effect, only nebivolol was able to prevent endothelial dysfunction. This study demonstrates for the first time that the acute NO-mediated vasodilatory action of nebivolol is also present during chronic treatment. Hence, nebivolol might become a new therapeutic tool with which to exert vascular protective effects against end-organ damage in conditions associated with NO deficiency.

This randomized, double-blind, placebo-controlled study investigated the effects of nebivolol on blood pressure, plasma renin and vasoactive hormones (aldosterone and atrial natriuretic peptide) and the heart (arrhythmias, left ventricular mass and ejection fraction) in 32 hypertensive Chinese patients aged 25-65 years. Patients received either placebo (3 men, 11 women) or nebivolol 5 mg (5 men, 13 women) once daily for 4 weeks. In the nebivolol group, a significant decrease in blood pressures (P less than 0.001) and heart rate (P less than 0.01) was seen. Nebivolol therapy also suppressed plasma renin and aldosterone concentration (P less than 0.02) but increased plasma atrial natriuretic peptide levels (P less than 0.03). No significant changes in routine blood biochemistry were demonstrated in either group. There was a tendency for left ventricular mass to decline, and left ventricular ejection fraction to rise during nebivolol therapy, but these changes did not reach statistical significance. There was no significant change in ectopic activity. None of the 32 subjects had adverse experiences requiring cessation of therapy. In conclusion, nebivolol in a dose of 5 mg daily is effective and well tolerated in patients with essential hypertension. It suppresses plasma renin and aldosterone and stimulates plasma atrial natriuretic peptide.

A simple, specific, accurate and stability indicating reversed phase liquid chromatographic method was developed for the determination of nebivolol hydrochloride in tablet dosage forms. A phenomenex Gemini C-18, 5 μm column having 250×4.6 mm i.d., with mobile phase containing methanol: acetonitrile: 0.02 M potassium dihydrogen phosphate (60:30:10, v/v/v; pH 4.0) was used. The retention time of nebivolol hydrochloride was 2.6 min. The linearity for nebivolol hydrochloride was in the range of 0.2-10 μg/ml. The recovery was found to be in the range of 98.68-100.86%. The detection limit and quantification limit were found to be 0.06 μg/ml and 0.2 μg/ml, respectively. Nebivolol stock solutions were subjected to acid, alkali and neutral hydrolysis, chemical oxidation and dry heat degradation. The degraded product peaks were well resolved from the pure drug peak with significant difference in their retention time values. The proposed method was validated and successfully applied to the estimation of nebivolol hydrochloride in tablet formulations.
