Seventeen patients in class IIIb/IV CHF (group 1) on intermittent intravenous milrinone therapy and 15 patients in class II/IIIa compensated CHF (group 2) on standard triple heart failure therapy were titrated on carvedilol. Success and adverse events during titration were compared between the 2 groups. Fifteen (88%) patients in group 1 and 14 (93%) patients in group 2 were successfully titrated on carvedilol over 8.1 +/- 1.8 weeks and 6.7 +/- 2.8 weeks, respectively. The target dose of carvedilol (25 or 50 mg twice daily) was achieved in 13 (87%) patients (group 1) and 14 (93%) patients (group 2). Seven (47%) patients in group 1 and 4 (28%) patients in group 2 had adverse events during carvedilol titration. Eight (53%) patients in group 1 were weaned off milrinone over a period of 8.4 weeks after carvedilol titration, whereas the rest of the patients had reduction in the frequency of infusion. Ten (63%) patients in group 1 improved by one or more functional classes.

Using Ca/Pi, carvedilol protected mitochondria from MPT induction, particularly in its high conductance form. Its effect was demonstrated by analyzing the decrease in mitochondrial swelling amplitude. Simultaneously, we observed inhibition of protein thiol group oxidation (p < 0.001). By contrast, carvedilol did not show any protective effect with Ca/Catr.

Various beta-blockers with distinct pharmacological profiles are approved in heart failure, yet they remain underused and underdosed. Although potentially of major public health importance, whether one agent is superior in terms of tolerability and optimal dosing has not been investigated. The aim of this study was therefore to compare the tolerability and clinical effects of two proven beta-blockers in elderly patients with heart failure.

Hospitalization for HF or death occurred in 30% of the patients on metoprolol and in 23% on carvedilol. Treatment with carvedilol was associated with a significantly decreased risk of hospitalization for HF or death when compared with metoprolol (hazard ratio [HR]: 0.70, [95% confidence interval (CI): 0.57 to 0.87], p = 0.001). This reduction in risk was further attenuated in the subgroup of cardiac resynchronization therapy with implantable cardioverter-defibrillator (CRT-D) patients (HR: 0.61 [95% CI: 0.46 to 0.82], p = 0.001) and CRT-D patients with left bundle branch block (LBBB) (HR: 0.51 [95% CI: 0.35 to 0.76], p < 0.001). Ventricular arrhythmias occurred in 26% and in 22%, respectively, of the patients receiving metoprolol or carvedilol (HR: 0.80 [95% CI: 0.63 to 1.00], p = 0.050). General use of beta-blockers and adherence in this study was high, and a clear dose-dependent relationship was found in carvedilol, but not in metoprolol.

Cardiodynamic changes due to beta-blocker carvedilol and low-intensity infrared laser radiation were compared in 115 patients with ischemic heart disease (IHD). The comparison has shown a similar positive effect on heart contractility and diastolic function. This gave arguments for feasibility of laser beam usage as a neurohormonal modulator in IHD patients to reduce cardiac remodulation and prevent cardiac failure.

Blood samples were collected for 24 hours after single doses of carvedilol were administered IV (175 microg/kg) or PO (1.5 mg/kg) by use of a crossover nonrandomized design. Carvedilol concentrations were detected in plasma by use of high-performance liquid chromatography. Plasma drug concentration versus time curves were subjected to noncompartmental pharmacokinetic analysis.

The time interval between airway obstruction and CA in the treatment group was significantly longer than in the control group (230 ± 27 vs 203 ± 24 seconds; P < 0.05). The rate of return of spontaneous circulation in the treatment group was significantly higher than in the control group (92% vs 50%; P < 0.05). Acidosis and increased glucose and tumor necrosis factor-α concentrations in the treatment group were significantly lower than in the control group.

In this single-centre, prospective, randomized study, 60 patients with dilated cardiomyopathy with an LVEF less than 40% and already receiving digoxin, ACE inhibitors and diuretics for six months as the standard therapy were randomly assigned to receive either carvedilol (n=30) or placebo (n=30). Patients received an initial dosage of 3.125 mg carvedilol or placebo twice daily for two weeks, which was then increased at two-week intervals (if tolerated), first to 6.25 mg, then to 12.5 mg, and, finally, to a target dosage of 25 mg twice daily. Clinical examinations, radionuclide studies, and determinations of plasma levels of tumour necrosis factor-alpha (TNF-a), interleukin (IL)-2 and IL-6 were performed at baseline and repeated four months after random assignment. Primary end points were New York Heart Association functional class, LV function and plasma cytokines levels. Eight patients died (seven in the placebo group, P=0.05). Patients treated with carvedilol had a significant improvement in functional class compared with the baseline values (P=0.001), with a decrease in the levels of cytokines (IL-6 [P=0.001] and TNF-a [P=0.001]). LVEF increased from 22.14+/-7.85% to 27.85+/-11.80% (P=0.002), but diastolic function did not change in the carvedilol group.

Spherically agglomerated solid dispersions of carvedilol (CAR) were prepared with polyvinyl-pyrrolidone (PVP) using acetone, water and dichloromethane as solvent, non-solvent and bridging liquid, respectively. The prepared agglomerates were evaluated for its percentage yield, drug content, morphology, thermal behavior, micromeritic properties, aqueous solubility and in vitro drug release. Differential scanning calorimetric and powder X-ray diffraction studies confirm that formulation process altered the crystalline nature of carvedilol. The recrystallized agglomerates exhibited significant increase (p < 0.05) in micromeritic properties than untreated carvedilol. Solubility and in vitro drug release studies indicated that the spherical agglomerates showed significant increase (p < 0.05) in solubility and dissolution rate than pure carvedilol alone.

TAC rats showed an increased diastolic interventricular septal thickness at week 5. At 10 weeks, Masson staining showed that left ventricular and renal glomerular fibrosis were significantly reduced in RDN compared with Sham group. In comparison to Sham group, hepatic perivascular fibrosis was attenuated in both RDN and Carvedilol group, so were the media thickness and the media/lumen of aorta. The plasma levels of B-type natriuretic peptide (BNP), Cystatin C (Cys-C), Alanine Transaminase, angiotensin II (Ang II), transforming growth factor beta 1 (TGF-β1), and malondialdehyde increased, and total superoxide dismutase (T-SOD) decreased in Sham but not in RDN group, compared with Control group. Both RDN and Carvedilol reduced the Cys-C and TGF-β1 levels, and restored T-SOD concentration, compared with Sham group. While only RDN lowered the plasma levels of BNP and Ang II. No significant effects of RDN on blood pressure (BP) and heart rate (HR) were oberved.

The subdivision of alpha adrenoceptors into the alpha 1 and alpha 2 classes was the impetus for the design of the selective alpha 1-adrenoceptor antagonists, which remain useful antihypertensives. alpha 2-Adrenoceptor agonists also have application as antihypertensive drugs, based on their ability to reduce sympathetic outflow. Likewise, subdivision of the beta adrenoceptors has lead to the development of selective beta 1-adrenoceptor antagonists as antihypertensive and selective beta 2 agonists as bronchodilators. In the past decade, both the alpha 1 and alpha 2 adrenoceptors have been further subdivided, each into three subclasses. In addition, there is strong functional evidence to suggest the presence of additional adrenoceptor subtypes, such as the "alpha 1L" adrenoceptor and "beta 4" adrenoceptor. alpha 1A (or alpha 1L)-Adrenoceptor antagonists have been evaluated for benign prostatic hyperplasia (BPH), and selective alpha 1A agonists for stress incontinence. Gene knockout experiments in mice suggest an important role for the alpha 1B adrenoceptor in the control of vascular tone. Hence, selective alpha 1B antagonists may offer a new approach toward hypertension. Although targeting of specific adrenoceptors can be used to optimize the therapeutic profile of a drug, there are also cases where blockade of multiple adrenoceptors is desirable, as with the alpha/beta-adrenoceptor antagonist carvedilol in congestive heart failure. It is possible that combination of affinities for selected adrenoceptor subtypes within a single molecule may be desirable for certain applications.

Fibroblasts isolated from hearts of adult rats were grown in 10% serum-containing media which induced an increase in cell number by 94%. After 48 h, treatment with 10 microM NE caused an even greater increase in cell number by 222%, i.e. another 128% (comitogenic effect). In contrast, NE alone had no effect on the growth of serum-deprived cells. EGF and PDGF-AA did not replace serum as the basic mitogen. After addition of NE to proliferating cells under serum conditions, there was a rapid, time-dependent significant activation of the p42/p44(MAPK) and of CREB for up to 60 and 120 min, respectively. In both cases, the maximum of activation was reached after 5 min. Application of FO (0.1-20 microM) caused a strong activation of CREB, while no increase in the phosphorylation of the p42/p44(MAPK) was detected. Treatment with 20 microM FO led to an identical increase in cell number as application of NE. Specific blockade of PKA with RpcAMPS prevented the activation of CREB and also the comitogenic effect of FO as well as of NE. The alpha- and beta-adrenergic receptor blocker carvedilol (10 microM) normalized all NE-induced effects. Prazosin and yohimbine, inhibitors of alpha(1)- and alpha(2)-adrenoceptor activation, respectively, did not influence the NE-evoked increase in cell number. In contrast, the non-selective beta-adrenoceptor blocker propranolol (1 microM) completely suppressed the comitogenic effect of NE. A similar effect was obtained with the specific beta(2)-adrenoceptor blocker ICI 118,551 (5 microM), while the beta(1)-adrenoceptor blocker metoprolol did not influence the increase in cell number.

Carvedilol limits myocardial necrosis resulting from coronary artery occlusion and reperfusion in a more pronounced manner than the pure beta adrenoceptor antagonist, propranolol. The cardioprotective effect of carvedilol, which reduced infarct size by 91%, may result from the combined effects of beta adrenoceptor blockade and vasodilatation, and possibly also from inhibition of intracellular calcium overload in cardiac cells resulting from antagonism of myocardial alpha 1 adrenoceptors and/or calcium channel blockade. The cardioprotection provided by carvedilol may ultimately be of benefit in hypertensive patients who are at risk for acute myocardial infarction.

Beta-adrenoceptor blockade did not affect a visual assessment of the autoradiographic image of 9MPA in hearts subjected to ischemia-reperfusion, but it accelerated the clearance of 9MPA in both the IR and non-IR. The administration of beta-blockade before ischemia could accelerate the recovery from ischemia-reperfusion injury by inhibiting myocardial FA accumulation before beta-oxidation.

Constipation is one of most frequent non-motor symptoms of Parkinson's disease (PD) and it may precede the clinical diagnosis of PD by years, with negative effects on quality of life. In contrast to motor features, levodopa is ineffective and possibly detrimental on constipation. Treatment of constipation in PD is non-specific and frequently unsuccessful. Stemming from a clinical observation of unexpected relief of bothersome constipation, abdominal bloating and pain after treatment with the beta-blocker carvedilol in one patient, we have evaluated the association between the use of beta-blockers and the presence of constipation in a large, unselected PD cohort.

A capillary electrophoresis method was used for assay of some degradation products of carvedilol. The optimized parameters were as; running buffer 80 mM acetate dissolved in methanol/ethanol mixture (65:35% v/v), applied voltage of 19 kV, temperature is 20 ºC and the wavelength range of 200-350 nm. The results indicate that the proposed capillary electrophoresis method could effectively separate carvedilol from its degradation products and can be employed as a stability indicating assay method. In addition, the presence of a new unknown degradation product was discovered by this method. In addition, capillary electrophoresis behaviour of carvedilol in photo/force degradation conditions gave valuable information concerning the dissimilarities of their ionization. Results indicated that the capillary electrophoresis proposed method can be used for the determination of carvedilol in human serum. Finally, accuracy of the proposed method was established by recovery experiments from spiked human serum samples.

Tablet splitting could be safer and easier when drug- and patient-specific criteria have been met. Tablet size, shape, and hardness may also play a role in the decision to split a tablet or not. Tablets containing drugs with a wide therapeutic index and long half-life might be more suitable candidates for division. Dose variation exceeded a proxy USP specification for more than one-third of sampled half tablets of bromazepam, carvedilol, bisoprolol, and digoxin. Drug content variation in half tablets appeared to be attributed to weight variation due to fragment or powder loss during the splitting process.

Prospective propensity-adjusted cohort study over 5 years on 1085 adults diagnosed with HF-PSF for the first time, in an integrated university-based health organization in Spain. The independent relationship between CT-βB and mortality and morbidity was analyzed, stratifying patients for comorbidity, after a multivariable adjustment for potential confounders.

Although we recently demonstrated that opening of a native aortic valve (AV) after left ventricular assist device (LVAD) implantation is a sufficient condition to prevent development of aortic insufficiency (AI), its preoperative predictors remain unknown. Data were obtained from 58 patients who had been treated with continuous flow LVAD for ≥ 6 months at our institute between 2006 and 2014. Opening of native AV was accomplished in 21 patients (36%) at postoperative 6 months. Uni/Multivariate logistic regression analyses demonstrated that a preoperative lower cumulative dose of β-blocker was the only independent predictor for postoperative opening of native AV (P = 0.020, OR 0.905) at the cutoff level of 4.5g (equivalent dose of carvedilol), calculated by an ROC analysis. Prevalence of native AV opening was increased gradually along with improvement of LV ejection fraction only in patients with preoperative insufficient β-blocker treatment during postoperative 6 months (P < 0.05 for both). Patients with opening of native AV had higher exercise capacity and a lower re-admission rate than those with closed native AV during 2-year LVAD support (5% versus 44%, P < 0.05). Opening of native AV during LVAD support is profoundly associated with LV reverse remodeling especially in patients with insufficient preoperative β-blocker exposure probably due to their better responsiveness to combination therapy with β-blocker and LVAD. Patients who accomplished native AV opening can enjoy better exercise performance and avoid re-admission due to cardiovascular events.

In 1983, carvedilol [1-[carbazolyl-(4)-oxy]-3-[(2-methoxyphenoxyethyl)amino]-2-propanol] was designed and developed as a beta-adrenoceptor antagonist with vasodilating activity for efficacious and safe treatment of hypertension and coronary artery disease. Carvedilol belongs to the 'third generation' of beta-adrenoceptor antagonists and shows selectivity for the beta1- rather than beta2-adrenoceptor. Carvedilol is also an alpha1-blocking agents, with around 2- to 3-fold more selectivity for beta1- than alpha1-adrenoceptors. This degree of alpha1-blockade is responsible for the moderate buy coreg vasodilator properties of carvedilol, being different from other beta-adrenoceptor antagonists. In addition, carvedilol is a potent antioxidant, with a 10-fold greater activity than vitamin E. Some carvedilol metabolites found in human plasma also exhibit antioxidative activity approximately 50- to 100-fold greater than carvedilol and other antioxidants. These unique properties of carvedilol, i.e. adrenergic (beta1, beta2 and alpha1) blockade and antioxidative activity, may be important in preventing progressive deterioration of left ventricular dysfunction and chronic heart failure. Recently, carvedilol has been demonstrated to reverse multidrug resistance (MDR) to anticancer drugs in tumor cells in vitro and its reversal effects were comparable with verapamil, which has been used in the first clinical trial for the reversal of MDR. This review introduces the reversal activity and usefulness against MDR, as well as an overview of the pharmacological and pharmacokinetic properties, of carvedilol.

In the carvedilol group, we found a progressive improvement of Doppler ultrasound scanning parameters after 4 months, with a significant increase of A wave (P <.005), deceleration time (DT; P <.02) and isovolumetric relaxation time (IVRT; P <.02). These improvements were confirmed after 1 year of follow-up, whereas patients in the placebo group did not shown any significant modifications. After 1 year, the differences in these groups were more significant for A wave (39 +/- 4 cm/sec carvedilol group vs 30 +/- 4 cm/sec placebo group; P <.0001), for E/A ratio (1.8 +/- 0.2 carvedilol group vs 2.6 +/- 0.5 placebo group; P <.0002), for DT 1(40 +/- 16 msec buy coreg carvedilol group vs 112 +/- 13 msec placebo group; P <.001), and for IVRT (74 +/- 8 msec carvedilol group vs 57 +/- 7 mesc placebo group; P <.0002). These changes seem to happen before systolic and morphological modifications.

The enantiospecific procedure for assaying carvedilol includes the extraction of the drug from plasma or urine with diisopropylether after alkalization of the sample with pH 9.8 buffer. After evaporation of the org. solvent a chiral derivatization is performed using S-(+)-naproxen buy coreg chloride. The HPLC separation of the diastereomeric amides is possible on a silica gel stationary phase with a mixture of n-hexane, dichloromethane, and ethanol as mobile phase. Detection of the products is performed by fluorescence measurement at 285/355 nm. Preliminary pharmacokinetic studies after i.v. infusion of racemic compound to healthy volunteers showed that the concentrations of the R-(+)-enantiomer exceeded those of the S-(-)-enantiomer. Overall, both carvedilol enantiomers exhibited a high clearance with preference for the S-enantiomer. The difference was even more expressed after p.o. dosage indicating a stereoselective first-pass effect with higher extraction of the levorotatory enantiomer, which is more potent with respect to beta-adrenoceptor antagonistic activity.

As an experimental model for reduced liver function rats with surgical portacaval shunts (pcs) may be used. Carvedilol, a nonselective beta-adrenoceptor antagonist with vasodilating activity, is extensively metabolised by phase I as well as phase II pathways. In order to study the stereoselective pharmacokinetics of carvedilol in liver disease, pcs and control rats were given rac-carvedilol intravenously and p.o. The carvedilol enantiomers and their conjugates were assayed in plasma, urine, and bile. Carvedilol was highly bound to plasma proteins; binding buy coreg was reduced by pcs. In all groups, the plasma concentrations of (R)-carvedilol exceeded those of (S)-carvedilol significantly. In comparison to the control group the plasma concentrations of both enantiomers increased after pcs, while the difference between the stereoisomers decreased. The total clearance decreased proportionally to the decrease in liver weight (30%). Both the apparent oral clearance, as well as its stereoselectivity were reduced, by up to 90 and 43%, respectively. The biliary clearance of the parent drug after i.v. dosage increased in rats with pcs due to the reduced hepatic metabolism.

We identified 35 reports, 17 of which met the inclusion criteria. These studies included 3,039 patients with follow-up ranging from 3 months to 2 years. Beta-blockade was associated with a trend toward mortality reduction in 13 studies. When all 17 reports were combined, beta-blockade significantly reduced all-cause mortality (random effect odds ratio [OR] 0.69, 95% confidence interval [CI] 0.54 to 0.88). A trend toward greater treatment effect was noted for nonsudden cardiac death (OR 0.58, 95% CI 0.40 to 0.83) compared with sudden cardiac death (OR 0.84, 95% CI 0.59 to 1.2). Similar reductions in mortality were observed for patients with ischemic (OR 0.69, 95% CI 0.49 to 0.98) and nonischemic cardiomyopathy (OR 0.69, 95% CI 0.47 to 0.99). The survival benefit was greater for trials of the drug buy coreg carvedilol (OR 0.54, 95% CI 0.36 to 0.81) than for noncarvedilol drugs (OR 0.82, 95% CI 0.60 to 1.12); however, the difference did not reach statistical significance (p = 0.10).

A simple, specific, sensitive, inexpensive and rapid HPLC method for enantioselective quantification of carvedilol in human plasma was developed in this study. S(-)- and R(+)-carvedilol and R(+)-propranolol as the internal standard were extracted from human plasma by liquid-liquid extraction using methyl tert-butyl ether. Enantioseparation was performed on a reverse-phase C18 Phenomenex Luna 5micron 150mmx2mm column after chiral derivatization with 2,3,4,6-tetra-O-acetyl-beta-d-glucopyranosyl isothiocyanate. The mobile phase was a mixture of water and acetonitrile. The peaks were detected using a fluorescence detector, where the excitation and emission wavelengths were set at 242 and 344nm, respectively. The limits of quantification for the S(-)- and buy coreg R(+)-carvedilol enantiomers were both 0.5ng/ml. Combined intra- and inter-day variations for both enantiomers were less than 8.3%. The combined accuracy for both enantiomers ranged from 91.7 to 104.7%. This method was used to assay the carvedilol enantiomers in human plasma samples obtained from heavily medicated heart failure patients within the framework of a clinical trial.

Carvedilol, a nonselective beta-adrenoceptor antagonist, has been shown to possess antioxidant effects and reduce the risk of hospitalization and death in patients with severe congestive heart failure, which is featured by the activation of pro-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-alpha), and leads to thrombotic complications. Thrombomodulin (TM) plays protective roles against thrombosis. Treatment of ECs with TNF-alpha resulted in a down-regulation in the TM expression in a time-dependent manner. Pre-treatment of ECs with carvedilol (1 and 10 microM) for 1 h significantly up-regulated the TM expression in ECs in response to TNF-alpha. When ECs were pre-treated with a nuclear factor-kappaB (NF-kappaB) inhibitor, i.e., parthenolide, their TNF-alpha-mediated down-regulation of TM expression was inhibited. Pre-treatment of ECs with carvedilol inhibited the NF-kappaB-DNA binding activity in ECs induced by TNF-alpha. Our findings provide insights into the mechanisms by which carvedilol buy coreg exerts anti-thrombotic effects by inducing TM expression in ECs in response to pro-inflammatory stimulation.

Treatment with beta-blockers is recommended to achieve and maintain adequate blood pressure control in patients with hypertension, and these agents have been shown to decrease cardiovascular risk factors in patients with both hypertension and type 2 diabetes mellitus. However, beta-blocker therapy also may worsen glycemic and lipidemic control and may lead to microalbuminuria. A recent study showed a better metabolic profile with carvedilol than with metoprolol in patients with both type 2 diabetes and hypertension in the presence of renin-angiotensin system blockade. This beneficial effect on metabolic components has been proposed as attributable to carvedilol's alpha-blocking effects or antioxidant properties. In this article, the pathophysiology of hypertension and type 2 diabetes and the association between them are reviewed, the pharmacologic properties Imdur 10 Mg of carvedilol are discussed, and clinical studies in the literature comparing carvedilol with selective beta-blockers in patients with both type 2 diabetes and hypertension are identified and evaluated. This information should be useful to practitioners when selecting the optimum beta-blocker for treating hypertension in patients with type 2 diabetes.

We previously reported that vitamin E prevents apoptosis in neurons during cerebral ischemia and reperfusion in stroke-prone spontaneously hypertensive rats (SHRSP). In this paper, we analyzed the effects of antihypertensives as well as vitamin E, which were added to neuron cultures after reoxygenation (20% O2) following hypoxia (1% O2). When added after hypoxia before reoxygenation, vitamin E conferred significant protection to neuronal cells. It was also shown that vitamin E conferred complete protection from neural cell death when added hypoxia and again before reoxygenation. At higher concentrations of vitamin E, strong neuroprotection was observed. Moreover, we verified that pretreatment with either amlodipine, carvedilol or dipyridamole consistently prevented cell death during hypoxia and reoxygenation (H/R). On the other hand, nilvadipine, a dihydropyridine-type calcium entry blocker, had no apparent effect on neuroprotection during H/R. The order of neuroprotective potency was vitamin E > dipyridamole > carvedilol > or = amlodipine > nilvadipine. In parallel experiments, we examined whether these antihypertensive agents were more effective when combined with vitamin E and dipyridamole. The results suggested that in our in vitro model system, antioxidants were the most important agents for the reduction of oxygen-free radical damage in cortical neurons. These findings suggest that amlodipine and carvedilol, with their antioxidant properties and antihypertensive activity, would be useful to inhibit neuronal cell death in the treatment of cerebrovascular stroke and neurodegenerative diseases in Cialis Online Purchase hypertensive patients.

A total of 25 patients with symptomatic congestive heart failure and 25 healthy individuals were enrolled in the study. Before introducing beta-blocker into their therapy regimens, baseline transthoracic echocardiography recordings were made and venous blood samples were drawn for establishing NT-proBNP levels. The patients were administered with a minimum dose of carvedilol. Three months after reaching the maximum tolerable dose, blood samples were drawn from the patients once again for NT-proBNP measurements, and transthoracic echocardiography was performed. There was a significant drop in plasma NT-proBNP levels at the end of the study in comparison to the baseline values (baseline: 381.20+/-35.06 pg/mL, at the end of the third month: 254.44+/-28.64 pg/mL; P < 0.001). While left ventricular end-diastolic and end-systolic diameters were observed to have significantly Propecia Prices decreased as a result of the therapy (P < 0.001), left ventricular ejection fraction (P<0.001) was established to have increased significantly.

A lot of epidemiological and intervention studies support the hypotensive action resulting from ingestion of foods rich in flavan 3-ols. However, the mechanisms of this action remain unclear. We have reported previously on the alteration of the micro- and systemic circulations after administration of a flavan 3-ol fraction (FL) derived from cocoa in mammals. We also confirmed that blood catecholamine levels increase significantly after administration of FL. In the present study, we examined whether adrenaline receptors are involved in the hemodynamic changes using several adrenaline receptor (AR) blockers. First, we confirmed that mean blood pressure (MBP) decreased significantly and aortic endothelial nitric oxide synthase (eNOS) levels increased significantly following oral treatment of 10mg/kg FL for 2 weeks in normal rats compared with vehicle administration. However, these changes were not observed with treatment of 1mg/kg (-)-epicatechin (EC), which contains nearly equivalent amount of 10mg/kg FL. Secondly, we observed that a single dose of FL produced different hemodynamic changes, such as a transient elevation in heart rate (HR) after ingestion of 1-100mg/kg FL, but not with 1mg/kg EC. Furthermore, although MBP rose transiently after 1 and 10mg/kg FL, this effect was not observed with 100mg/kg or 1mg/kg EC. The increases in HR, MBP, and aortic phosphorylated Augmentin S Suspension eNOS (p-eNOS) induced by 10mg/kg FL were prevented completely by pretreatment with the AR blocker, carvedilol. Combination treatment with 100mg/kg FL and an α1AR blocker, prazosin, significantly reduced MBP, whereas the elevation in HR was enhanced. In addition, after pretreatment with the β2AR blocker, butoxamine, we observed no significant hemodynamic changes with or without 100mg/kg FL. Moreover, the combination of 100mg/kg FL and the α2AR blocker, yohimbine, markedly increased MBP, HR and aortic p-eNOS level. These results suggested that the postprandial hemodynamic changes after a single oral dose of FL were induced by an adrenergic effect. This adrenomimetic activity suggested the involvement of a hypotensive effect of FL.

Carvedilol exerted protective effects against volume-overload cardiomyopathy in this model of aortic valve regurgitation with preserved ejection fraction. These results suggest a protective class effect of β-blockers. Combined with the recent publication of promising human data, our findings support the need to carefully design a prospective study in humans to evaluate the effects of β-blockers in chronic aortic valve regurgitation.

Carvedilol is a novel, multiple-action cardiovascular drug that is currently approved in many countries for the treatment of hypertension. The reduction in blood pressure produced by carvedilol results primarily from beta-adrenoceptor blockade and vasodilation, the latter resulting from alpha 1-adrenoceptor blockade. These actions, as well as several of the other activities of carvedilol, are associated with cardioprotection in animal models that occurs to a degree that is greater than that observed with other drugs. The multiple actions of carvedilol may also provide the underlying rationale for the use of the drug in the treatment of coronary artery disease and congestive heart failure. By virtue of being both a beta-blocker and a vasodilator, carvedilol significantly decreases myocardial work by reducing all three components of myocardial oxygen demand, namely, heart rate, contractility, and wall tension. The vasodilatory effects of carvedilol reduce afterload, and the resulting decrease in impedance to left ventricular ejection offsets the negative inotropic effect that would normally result from beta-blockade. As a consequence, stroke volume and cardiac output are maintained or even increased in animals and in patients with congestive heart failure who are treated with carvedilol. Carvedilol and several of its metabolites are potent antioxidants, and this activity may account, in part, for the cardioprotective effects of the drug observed in animal models of acute myocardial ischemia and, in theory, could also serve to protect the myocardium of patients with hypertension, coronary artery disease, and congestive heart failure, in which oxidative stress is now recognized to occur. The antioxidant effects of carvedilol may both inhibit the direct cytotoxic actions of reactive oxygen radicals and prevent oxygen-radical induced activation of transcription factors and genes associated with inflammatory and remodeling processes. Accordingly, carvedilol inhibits the gene expression of the intracellular adhesion molecule-1 (ICAM-1), an adhesion molecule for polymorphonuclear leukocytes, which typically infiltrate the myocardium under conditions of ischemia and may exacerbate ischemic injury. The antioxidant activity of carvedilol has been shown to inhibit the oxidation of low density lipoprotein (LDL) in vitro, thereby preventing the formation of this cytotoxic and atherogenic form of LDL. It follows, therefore, that in animal models of hyperlipidemia, carvedilol attenuates aortic lipid accumulation and decreases the aortic content of monocytes and foam cells, and at the same time it has been shown to preserve endothelial integrity and function. These actions of carvedilol are not shared by other beta-blockers or by other drugs currently used in the management of hypertension, coronary artery disease, or congestive heart failure. The multiple actions of carvedilol may provide the underlying pharmacologic rationale for the use of this drug in the treatment of patients with coronary artery disease or congestive heart failure, and these actions may account, at least in part, for the reduction in mortality produced by carvedilol in clinical trials involving patients with congestive heart failure. Likewise, these actions of carvedilol may also provide protection, beyond that afforded from reduction in blood pressure, against secondary organ damage in hypertensive patients treated with the drug.

Reactive oxygen species (ROS) and antioxidant enzymes are required to maintain homeostasis. The loss of this balance can cause excessive ROS production and damage to the cardiovascular tissues. Angiotensin II receptor blockers (ARBs) and β-blockers with antioxidant effects may inhibit ROS in the cardiovascular system. In this study, we directly compared the effects of ARBs and β-blockers with antioxidant properties on cardiovascular protection and the regulation of endothelial progenitor cell (EPC) numbers in the setting of oxidative stress in hypertensive rats. To compare the effects of the drugs, animals were divided into the following groups: Wistar-Kyoto rats (WKY), untreated spontaneously hypertensive rats (SHR) and SHR treated with tempol (TEMP, 5 mg kg(-1) per day), trichlorothiazide (TCTZ, 1.6 mg kg(-1) per day), atenolol (25 mg kg(-1) per day), nebivolol (NEBL, 5 mg kg(-1) per day), carvedilol (CVDL, 30 mg kg(-1) per day) or telmisartan (TERT, 5 mg kg(-1) per day). Following 2 weeks of treatment, blood pressures (BPs) and aortic wall thicknesses were similarly reduced in each antihypertensive drug-treated group. Superoxide anion and malondialdehyde levels were significantly reduced following treatment with NEBL, CVDL and TERT. Additionally, the expression levels of NADPH oxidase subunits were also reduced in the TERT-, CVDL- and NEBL-treated groups. Furthermore, these drugs improved both EPC numbers and the expression levels of peroxiredoxin 2 (Prdx2), an antioxidant enzyme, in the heart and kidneys but not the aorta. Cardiac Prdx2 expression, in particular, was markedly improved by TERT, NEBL and CVDL treatment, and renal Prdx2 expression was enhanced by TEMP. Our data indicate that short-term treatment with TERT may have more beneficial effects on cardiovascular protection, EPC number improvements and Prdx2 expression compared with CVDL and NEBL. In conclusion, TERT may positively modulate the balance between oxidative stress and antioxidant properties and demonstrate capabilities beyond its BP-lowering effects.
