Beta-blockers play a pivotal role in the treatment of chronic systolic heart failure. However, the pharmacological family of beta-blockers is inhomogeneous regarding their pharmacological properties and their clinical effects can differ substantially according to different pharmacological properties. Because of vasodilator effects, the third generation of beta-blockers has additional potential across the cardiovascular diseases, from hypertension to heart failure. Nebivololol has both high selectivity for beta1-adrenergic receptors, no intrinsic sympathetic activity and ability to stimulate endothelial nitric oxide production. Such properties result in specific hemodynamic effects compared with others beta-blockers. Such properties also result in both high tolerability and positive metabolic effects which are crucial in high-risk groups. In the SENIORS trial, nebivolol demonstrated its efficacy and high tolerability in elderly patients with chronic heart failure irrespective of the left ventricular ejection fraction. More clinical trials would be useful to exhibit specific benefits of nebivolol in other high-risk groups of patients.

Current evidence indicates that nebivolol 5 mg once daily is a well tolerated beta-blocker, which is as effective as once daily atenolol and other classes of antihypertensive agents. It may therefore be recommended as a useful alternative first-line treatment option for the management of patients with mild to moderate uncomplicated essential hypertension.

Nebivolol, a clinically important antihypertensive drug, mainly metabolized by cytochrome P450 (CYP) 2D6, shows wide interindividual variability in pharmacokinetics. The CYP2D6*10 allele (100C>T; rs1065852), present at a high frequency in the Chinese population, is associated with alteration in the pharmacokinetics of many drugs, but its effect on the pharmacokinetics of nebivolol is unknown. The aim of our study was to investigate whether the CYP2D6*10 genotype and phenotype are associated with changes in the pharmacokinetics of nebivolol in Chinese subjects.

Twelve healthy subjects were randomized in an open, two-way cross-over study. beta 1-Blocking potency and beta 1-adrenoceptor selectivity of nebivolol 5 mg once daily (o.d.) were compared with those of atenolol at three doses (25, 50 and 100 mg) o.d. Measurements were performed after 1 and 7 days of drug intake. beta 1-Adrenoceptor potency was assessed by the percentage decrease in exercise-induced tachycardia (delta EIT) during beta-blockade. beta 1-Selectivity of nebivolol and atenolol were investigated using the heart rate response to isoprenaline at equipotent beta 1-blocking dosages of both drugs. alpha 1-Blockade of nebivolol was measured using the phenylephrine dose-response test.

Mirabegron resulted in a relaxation of phenylephrine-evoked CC contractions in a concentration-dependent manner and SR59230A antagonised the mirabegron-induced relaxations in HCC and rat CC. Other inhibitors, L-NAME, ODQ, and methylene blue, did not affect the mirabegron-induced relaxation responses. Mirabegron relaxation responses at concentrations (0.1-10 μm) were enhanced by fasudil (ROCK inhibitor) in rat but not in HCC strips. KCl-induced contractions in HCC and rat CC were partially inhibited by mirabegron. In vivo, ICI of mirabegron (doses of 0.1-1 mg/kg) had a minor effect on ICP when compared with vehicle administration. Immunohistochemistry data showed β3 -adrenoceptors localised in the smooth muscle cells of the HCC and rat CC.

Nebivolol is a beta-adrenergic receptor antagonist with a dual mechanism of action. It shows high selectivity for beta(1)-adrenergic receptors and appears to have nitric oxide-mediated vasodilatory activity. Once-daily nebivolol effectively lowered BP in patients with mild to moderate hypertension in four randomized, double-blind, placebo-controlled, 12-week trials. Trough sitting DBP and SBP were reduced to a significantly greater extent in nebivolol than in placebo recipients in trials in demographically heterogenous hypertensive patient groups, as well as in trials involving only Black patients and in patients continuing previous stable antihypertensive drug therapies. Treatment response (defined as a mean sitting DBP <90 mmHg or a >or=10 mmHg reduction from baseline) rates were significantly higher in nebivolol versus placebo recipients in trials enrolling patient groups considered representative of the US hypertensive population (46-65% vs 25%), in Black patients (57-64% vs 27%), and in patients concurrently treated with other antihypertensive drugs (53-65% vs 41%). Nebivolol was generally well tolerated in the treatment of hypertension, with the majority of adverse events described as being mild or moderate in severity. The incidences of fatigue, bradycardia, dyspnea, depression, and erectile dysfunction (events commonly associated with beta-adrenergic receptor antagonist use) did not significantly differ between nebivolol and placebo recipients in the 12-week trials.

With the perspective of functional myocardial regeneration, we investigated small cardiomyocytes bordering on microdomains of fibrosis, where they are dedifferentiated re-expressing fetal genes, and determined: (1) whether they are atrophied segments of the myofiber syncytium, (2) their redox state, (3) their anatomic relationship to activated myofibroblasts (myoFb), given their putative regulatory role in myocyte dedifferentiation and redifferentiation, (4) the relevance of proteolytic ligases of the ubiquitin-proteasome system as a mechanistic link to their size, and (5) whether they could be rescued from their dedifferentiated phenotype. Chronic aldosterone/salt treatment (ALDOST) was invoked, where hypertensive heart disease with attendant myocardial fibrosis creates the fibrillar collagen substrate for myocyte sequestration, with propensity for disuse atrophy, activated myoFb, and oxidative stress. To address phenotype rescue, 4 weeks of ALDOST was terminated followed by 4 weeks of neurohormonal withdrawal combined with a regimen of exogenous antioxidants, ZnSO4, and nebivolol (assisted recovery). Compared with controls, at 4 weeks of ALDOST, we found small myocytes to be: (1) sequestered by collagen fibrils emanating from microdomains of fibrosis and representing atrophic segments of the myofiber syncytia, (2) dedifferentiated re-expressing fetal genes (β-myosin heavy chain and atrial natriuretic peptide), (3) proximal to activated myoFb expressing α-smooth muscle actin microfilaments and angiotensin-converting enzyme, (4) expressing reactive oxygen species and nitric oxide with increased tissue 8-isoprostane, coupled to ventricular diastolic and systolic dysfunction, and (5) associated with upregulated redox-sensitive proteolytic ligases MuRF1 and atrogin-1. In a separate study, we did not find evidence of myocyte replication (BrdU labeling) or expression of stem cell antigen (c-Kit) at weeks 1-4 ALDOST. Assisted recovery caused complete disappearance of myoFb from sites of fibrosis with redifferentiation of these myocytes, loss of oxidative stress, and ubiquitin-proteasome system activation, with restoration of nitric oxide and improved ventricular function. Thus, small dedifferentiated myocytes bordering on microdomains of fibrosis can re-differentiate and represent a potential source of autologous cells for functional myocardial regeneration.

Both NEB as well as E2 decreased cellular stiffness to a similar extent (NEB: 0.83 +/- 0.03 pN/nm, E2: 0.87 +/- 0.03 pN/nm, vehicle: 2.19 +/- 0.07 pN/nm), whereas metoprolol had no effect on endothelial stiffness (2.07 +/- 0.04 pN/nm, all n = 60, P < 0.01). The decrease in stiffness occurred as soon as 5 min after starting NEB incubation. The effects are mediated through nongenomic ER[beta] pathways, as ER[alpha] is not translated into measurable protein levels in EAHy-926. Furthermore, NEB increased cell volume by 48 +/- 4% and apical surface by 34 +/- 3%. E2 had comparable effects. Tamoxifen, ICI and N[omega]-nitro-L-arginine methyl ester substantially diminished the effects of NEB and E2.

Slow coronary flow (SCF) is the phenomenon of slow progression of angiographic contrast in the coronary arteries in the absence of stenosis in the epicardial vessels in some patients presenting with chest pain. There are no definite treatment modalities for patients with SCF. Our aim was to investigate the efficacy of nebivolol in patients with slow coronary flow by monitoring its effects on endothelial function and different markers of inflammation. Forty-two patients (16 females, 26 males; mean age, 55 +/- 10) with slow coronary flow (SCF) were included in the study. After baseline assessment, the patients were administered nebivolol 5 mg once daily. After 12 weeks of nebivolol therapy, the biochemical and ultrasonographic examinations were repeated. Chest pain relief was detected in 38 patients after treatment (90%). Systolic and diastolic blood pressure and high sensitive CRP were significantly decreased after nebivolol therapy. Among brachial artery dilation variables that reflect endothelial function, basal resistive index (RI), post-flow mediated dilation RI, and post-nitrate mediated dilation RI were significantly decreased after therapy. Nebivolol is effective at improving endothelial function in patients with SCF. It controls chest pain, decreases CRP, and has favorable effects on brachial artery dilation variables in patients with coronary slow flow.

It is unclear whether carvedilol and nebivolol produce different effects on short-term left ventricle (LV) systolic function in heart failure (HF). These drugs could improve systolic and diastolic functions of the LV. Thus, we aimed to compare their effects on LV systolic functions in patients with non-ischemic HF.

The aim of the current study was to characterize the effects of the novel β-adrenergic antagonist nebivolol on central aortic blood pressures, arterial properties, and nitroxidergic activity in individuals with prehypertension. Prehypertension is emerging as a major risk factor for several adverse cardiovascular consequences. Increased pulse wave velocity, aortic augmentation index, and aortic blood pressures have been linked with augmented risk of cardiovascular disease and mortality. While the effects of antihypertensive drugs on these parameters in hypertensive patients have been studied, there are limited data so far in prehypertension. Fifty individuals with prehypertension were randomized to either nebivolol (5 mg per day) or placebo in a double-blind clinical trial. Patients underwent measurement of pulse wave velocity as well as aortic blood pressure and aortic augmentation index via pulse wave analysis at baseline and 8 weeks. Patients also had blood and urine biochemistries done at each visit. Nebivolol achieved significant reductions in central aortic systolic (P=.011), diastolic (P=.009), and mean arterial blood pressure (P=.002). Pulse wave velocity trended toward improvement but did not achieve significance (P=.088). Nitric oxide production, measured as urinary nitrite/nitrite excretion, also rose substantially in the nebivolol group (by approximately 60%, P=.030). Central blood pressures can be effectively lowered by β-blockade while patients are still in the prehypertension phase, and the effects may be coupled to improve nitric oxide release by the drug.

(D-L) Nebivolol is a new beta 1-selective adrenoceptor blocker which in normal individuals preserves rest and exercise hemodynamics. We assessed the effects of the enantiomers (L- and D-nebivolol) on left ventricular (LV) systolic and diastolic function and compared their effects with those of the racemic mixture. LV angiography (+Millar) was performed before and after intravenous (i.v.) infusion of either D- or L-nebivolol (1.25-2.5 mg, n = 22) in patients with ischemic heart disease and previous myocardial infarction. Neither L- nor D-nebivolol produced significant changes in heart rate (HR), peak (+) dP/dt, (dP/dt) DP40, cardiac index (CI) or ejection fraction (EF). Diastolic distensibility, evaluated from the shift of the pressure-volume data at the time of mitral valve opening, did not improve after D- or L-enantiomers administration. In contrast, both D-L-nebivolol 2.5 mg (n = 9) and atenolol 15 mg (n = 9) significantly reduced HR and peak (+) dP/dt, but in comparison to atenolol D-L nebivolol improved EF (+4% after D-L nebivolol vs. -4% after atenolol; p < 0.05 D-L nebivolol vs. atenolol) and maintained cardiac output CO, (+2% vs. -21%; p < 0.05 between groups). Moreover, unlike any of the other drugs in the study, the racemate shifted the diastolic pressure-volume data downward, suggesting improved LV distensibility. The beneficial effects of nebivolol on LV systolic and diastolic function appears to require the presence of both D- and L-enantiomers.

The objective of this 12-week double-blind randomized multicentre study was to compare the efficacy and tolerability of nebivolol, a recently developed beta-blocking agent with vasodilating properties, to the classical beta-blocker atenolol. After a placebo run-in phase, 205 mild-to-moderate middle-age essential hypertensives were randomized to either nebivolol 5 mg daily (n = 105) or atenolol 100 mg daily (n = 100) over a period of 12 weeks. The primary endpoint of the study was the change in sitting systolic and diastolic blood pressure (SBP and DBP respectively) from baseline to week 12 of treatment. The two drugs induced similar significant antihypertensive effects, the SBP and DBP reduction amounting to -18.2 +/-14.0 and -14.6 +/-7.9 mmHg (mean +/- SD) for atenolol and -19.1 +/-12.9 and -14.8 +/- 7.1 for nebivolol (p < 0.01 for all). This was the case also for standing blood pressure. Sitting and standing heart rate values were significantly reduced by both drugs, the bradicardic response induced by nebivolol treatment being significantly less than atenolol. Distribution of responders and non- responders was similar for nebivolol and atenolol, while the former drug showed a better tolerability profile and a lower incidence of side-effects. These data provide evidence, that, for the same antihypertensive effects, nebivolol shows a better tolerability profile than atenolol and a lower incidence of adverse effects.

The third generation β-blockers possess important ancillary properties besides inhibiting β-adrenoceptors. Among them, nebivolol activates nitric oxide synthase (NOS). Nebivolol and carvedilol preserve NOS activity by reducing asymmetrical dimethylarginine (AMDA) and enhance the bioavailability of nitric oxide (NO) because of their antioxidant properties. Concerning the treatment of hypertension and chronic heart failure, these third generation β-blockers show distinct advantages resulting from their NO-dependent effects (vasodilatation, anti-proliferation and cardioprotection), which may translate into a more effective clinical outcome than that obtained with the conventional β-blockers. Impaired NOS activity and reduced NO bioavailability are common initiators of cardiovascular dysfunction. Thus, owing to their NO-mediated actions, the new generation β-blockers should find more clinical applications in the treatment of cardiovascular diseases.

This study assessed blood pressure (BP) reductions and response rates following addition of nebivolol to ongoing antihypertensive therapy in patients with uncontrolled stage I-II hypertension despite antihypertensive treatment. Patients with an average sitting diastolic BP (SiDBP) > or =90 and < or =109 mm Hg while taking an antihypertensive regimen were included in this double-blind, placebo-controlled, parallel-group study. The primary efficacy end point was reduction from baseline to week 12 in mean trough SiDBP. In total, 669 patients were randomized to once-daily nebivolol 5, 10 or 20 mg or placebo. Addition of nebivolol 5, 10 and 20 mg significantly reduced BP; placebo-subtracted least squares mean reductions in trough SiDBP were -3.3, -3.5 and -4.6 mm Hg, respectively (P<0.001) and -5.7, -3.7 and -6.2 mm Hg in trough sitting systolic BP (SiSBP), respectively (P< or =0.015). Adding nebivolol 5-20 mg resulted in significantly more responders (SiDBP <90 or > or =10 mm Hg reduction; range: 53.0-65.1 vs 41.3% with placebo; P< or =0.028) and significantly better control rates (SiSBP/SiDBP <140/90 mm Hg; range: 41.3-52.7 vs 29.3% with placebo; P< or =0.029). Nebivolol was well tolerated; the incidence of adverse events with nebivolol was similar to that with placebo (40.2 vs 38.9%, respectively; P=0.763). Addition of once-daily nebivolol to ongoing antihypertensive therapy provided significant additional BP reductions and better response rates in patients with uncontrolled hypertension and was well tolerated.

We studied 3741 patients with mild hypertension for 6 months who were being treated with the beta-blocker nebivolol 5 mg daily. Blood pressures were measured after 10 minutes in the supine position and after 1 minute in the standing position. Overall, systolic and diastolic blood pressures rose slightly while standing, whereas pulse pressures remained unchanged. When previously untreated patients (n=2085) >60 and <60 years of age were assessed separately, supine pulse pressures were consistently higher in the elderly group compared with those of the younger subjects by 6 to 11 mm Hg (P<0.001 to 0.0001). However, while standing, pulse pressures rose in the younger subjects, whereas they tended to fall in the elderly group. After 6 months of beta-blockade, this pattern was unchanged in the younger subjects but reversed into significant rise of pulse pressures in the elderly group by 4 (SD 1) mm Hg (P<0.001). In the patients previously treated with other classes of antihypertensive drugs (n=712), the effects were essentially the same.

In the present study, we investigated the cardiovascular effects of dl-nebivolol, a newly synthetized, chemically novel, beta 1-adrenoceptor antagonist and its enantiomers, d-nebivolol (SRRR) and l-nebivolol (RSSS), in closed-chest anesthetized dogs, using atenolol as a reference substance. Results from preliminary studies in vitro indicate that d-nebivolol is the beta 1-adrenoceptor antagonist and that l-nebivolol is practically devoid of beta-adrenoceptor-blocking properties. Unlike atenolol, dl-nebivolol does not depress left ventricular function and slightly, but significantly, reduces peripheral vascular resistance over the dose range from 0.0025 to 0.04 i.v. These observations are likely to be clinically relevant because one daily oral dose of 5 mg dl-nebivolol effectively lowers arterial blood pressure in patients with hypertension. The favorable hemodynamic profile of dl-nebivolol can be ascribed to the l-enantiomer because the cardiovascular effects of this enantiomer are similar to those of the racemate. The cardiovascular profile of the d-enantiomer is similar to buy bystolic that of atenolol, albeit that its depressant effect on left ventricular function occurs at higher doses.

Neurohormonal activation with attendant aldosteronism contributes to the clinical appearance of congestive heart failure (CHF). Aldosteronism is intrinsically coupled to Zn and Ca dyshomeostasis, in which consequent hypozincemia compromises Zn homeostasis and Zn-based antioxidant defenses that contribute to the CHF prooxidant phenotype. Ionized hypocalcemia leads to secondary hyperparathyroidism with parathyroid hormone-mediated Ca overloading of diverse cells, including cardiomyocytes. When mitochondrial Ca overload exceeds a threshold, myocyte necrosis follows. The reciprocal regulation involving cytosolic free [Zn]i as antioxidant and buy bystolic [Ca]i as prooxidant can be uncoupled in favor of Zn-based antioxidant defenses. Increased [Zn]i acts as a multifaceted antioxidant by: (1) inhibiting Ca entry through L-type channels and hence cardioprotectant from the Ca-driven mitochondriocentric signal-transducer effector pathway to nonischemic necrosis, (2) serving as catalytic regulator of Cu/Zn-superoxide dismutase, and (3) activating its cytosolic sensor, metal-responsive transcription factor that regulates the expression of relevant antioxidant defense genes. Albeit present in subnanomolar range, increased cytosolic free [Zn]i enhances antioxidant capacity that confers cardioprotection. It can be achieved exogenously by ZnSO4 supplementation or endogenously using a β3-receptor agonist (eg, nebivolol) that enhances NO generation to release inactive cytosolic Zn bound to metallothionein. By recognizing the pathophysiologic relevance of Zn dyshomeostasis in the prooxidant CHF phenotype and by exploiting the pharmacophysiologic potential of [Zn]i as antioxidant, vulnerable cardiomyocytes under assault from neurohormonal activation can be protected and the myocardium spared from adverse structural remodeling.

Nebivolol is a novel, highly selective beta(1)-receptor blocker that causes peripheral vasodilation by increasing the production and release of nitric oxide and decreasing nitric oxide degradation. The nitric oxide-mediated effects of nebivolol lead to decreases in systemic vascular resistance and large artery stiffness and possible reversal of endothelial dysfunction. Clinical studies have shown nebivolol to be at least as effective at lowering blood pressure as other antihypertensive drugs, including other beta-blockers. The most frequent adverse events reported in nebivolol clinical trials were transient headache, dizziness, and tiredness. In a large trial in patients with heart failure, nebivolol was shown to reduce the composite endpoint of mortality and hospitalizations. Nebivolol is highly lipophilic and is rapidly absorbed after oral administration. The nebivolol dose most commonly used in clinical trials for hypertension was 5 mg daily; no significant further decreases in blood pressure were shown with higher doses. The average dose in clinical trials for patients Celebrex 500 Mg with heart failure was 5-10 mg daily. Dosage adjustments are recommended in elderly patients and patients with severe renal impairment.

This review provides a systematic overview of the influence of the third generation beta-adrenoceptor antagonists on vascular and/or endothelial function at a cellular level as well as of the advantages of their application in hypertension, heart failure and coronary artery disease. Drugs antagonizing the beta-adrenoceptors have been in use for the treatment of hypertension for decades. In systolic heart failure and post-myocardial infarction, beta-adrenoceptor antagonists were proven to be effective in decreasing the number of deaths and improving morbidity Strattera Online . However, betaadrenoceptor antagonists are a heterogeneous drug group, consisting of agents with different selectivity for adrenoceptors and/or additional effects in heart and peripheral circulation. Beta-adrenoceptor antagonists comprise a multitude of different agents, which may have additional properties exceeding the pure receptor blockade. These features may provide additional benefit in the treatment of hypertension. The third generation drug nebivolol exerts a nitric oxide-mediated vasodilating activity which has positive effects on intima and media thickness and arterial rigidity, a major risk factor in cardiovascular disease. Moreover, anti-proliferative, anti-inflammatory, and anti-oxidative properties have been detected for carvedilol and nebivolol, contributing to their additional value in treatment of hypertension and heart failure.

The SENIORS trial evaluated the effects of nebivolol and enrolled 2128 patients ≥70 years with Adalat Tablets HF (ejection fraction ≤35%, or recent HF admission). We randomly selected 1400 patients from the full dataset to produce a derivation cohort and the remaining 728 patients were used as a validation cohort. Baseline variables were entered into a bootstrap model with 200 iterations to determine their association with two outcomes, the composite of all-cause mortality or cardiovascular hospitalization, or all-cause mortality alone. Variables retaining a significant association with these outcomes in a multivariate model were used to develop a risk prediction score tested in the validation cohort. Five factors were associated with increased risk of both outcomes in the multivariate model: higher New York Heart Association class, higher uric acid level, lower body mass index, prior myocardial infarction, and larger left atrial (LA) dimension. For the composite outcome, peripheral arterial disease, years with heart failure, right bundle branch block, diabetes mellitus, and orthopnoea were also retained. For all-cause mortality, creatinine, 6 min walk test distance, coronary artery disease, and age were retained.

Nebivolol is a selective β₁-adrenoceptor antagonist which, in addition, displays endothelium-dependent vasodilating properties in humans and other species. β₃-adrenoceptors have been proposed to be a molecular target of nebivolol-induced vasodilatation. Therefore, we have investigated possible β₃-adrenoceptor agonism by nebivolol for relaxation of the human and rat urinary bladder (prototypical β₃-adrenoceptor-mediated responses) as well as for cAMP accumulation in Chinese hamster ovary cells stably transfected with the human β-adrenoceptor subtypes. Nebivolol concentration-dependently relaxed both human and rat isolated urinary bladder strips but with low potency, similar to that reported for vasodilatation. However, nebivolol-induced bladder relaxation in either species was not inhibited by the β₃-adrenoceptor antagonist SR 59,230A (10μM), although this compound inhibited the isoprenaline-induced relaxation with the expected potency. In radioligand binding studies nebivolol had lower affinity for human β₃-adrenoceptors than the other two β-adrenoceptor subtypes, but this low affinity was in line with its potency to relax the bladder or isolated blood vessels. In functional studies nebivolol even in high concentrations did not stimulate cAMP formation via any of the three cloned human β-adrenoceptors or in rat bladder smooth muscle cells. Taken together these data demonstrate that nebivolol can relax not only vascular but also urinary bladder smooth muscle. However, they do not support the hypothesis that nebivolol is an agonist at cloned human β₃-adrenoceptors or in rat or human urinary bladder.

Both NEB as well as E2 decreased cellular stiffness to a similar extent (NEB: 0.83 +/- 0.03 pN/nm, E2: 0.87 +/- 0.03 pN/nm, vehicle: 2.19 +/- 0.07 pN/nm), whereas metoprolol had no effect on endothelial stiffness (2.07 +/- 0.04 pN/nm, all n = 60, P < 0.01). The decrease in stiffness occurred as soon as 5 min after starting NEB incubation. The effects are mediated through nongenomic ER[beta] pathways, as ER[alpha] is not translated into measurable protein levels in EAHy-926. Furthermore, NEB increased cell volume by 48 +/- 4% and apical surface by 34 +/- 3%. E2 had comparable effects. Tamoxifen, ICI and N[omega]-nitro-L-arginine methyl ester substantially diminished the effects of NEB and E2.
