Abstract
INTRODUCTION The safety of β2-AR antagonists in the treatment of patients with COPD continues to be a topic of research and discussion within the medical community. Emerging evidence suggests potentially benefits in the management of this complex respiratory condition. However, antagonists that display a preference for β2-AR over β1-AR present a complex therapeutic challenge in COPD management, necessitating an understanding of differences in their pharmacological profiles and clinical implications. AREAS COVERED An overview of the mechanisms of action of β2-AR antagonists and their potential impact on respiratory function, their pharmacological interactions, clinical implications, and future perspectives in COPD. EXPERT OPINION β-Blockers have the potential to become a versatile class of therapeutic agents with benefits beyond their original cardiovascular use. However, the one-size-fits-all approach of prescribing β-blockers regardless of their receptor selectivity to COPD patients with concomitant heart disease may not be appropriate. Instead, it is advisable to develop an individualized treatment strategy based on a thorough assessment of the patient's overall health. The use of non selective β2-AR antagonists, functioning as inverse agonists at β2-ARs, has garnered interest and debate, but further research efforts should focus on elucidating the optimal use of β-AR antagonists in COPD, balancing cardiovascular benefits with potential respiratory risks to enhance outcomes and quality of life for individuals living with this debilitating respiratory condition.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is associated with multiple comorbidities, which impact negatively on patients and are often underdiagnosed, thus lacking a proper management due to the absence of clear guidelines. Purpose To elaborate expert recommendations aimed to help healthcare professionals to provide the right care for treating COPD patients with comorbidities. Methods A modified RAND-UCLA appropriateness method consisting of nominal groups to draw up consensus recommendations (6 Spanish experts) and 2-Delphi rounds to validate them (23 Spanish experts) was performed. Results A panel of Spanish internal medicine experts reached consensus on 73 recommendations and 81 conclusions on the clinical consequences of the presence of comorbidities. In general, the experts reached consensus on the issues raised with regard to cardiovascular comorbidity and metabolic disorders. Consensus was reached on the use of selective serotonin reuptake inhibitors in cases of depression and the usefulness of referring patients with anxiety to respiratory rehabilitation programmes. The results also showed consensus on the usefulness of investigating the quality of sleep, the treatment of pain with opioids and the evaluation of osteoporosis by lateral chest radiography. Conclusion This study provides conclusions and recommendations that are intended to improve the management of the complexity of patients with COPD and important comorbidities, usually excluded from clinical trials.

Abstract
An experimental model of ovalbumin (OVA) induced asthma was used to assess the effects of nebivolol, the third-generation selective β1-adrenergic receptor blocker, on airway reactivity, lung inflammation, and oxidative stress markers. The asthma induction protocol was done by OVA sensitization and challenge. Guinea pigs were classified into control, asthmatic, or asthmatic receiving nebivolol either 7.5 or 15 mg·kg-1·day-1 orally. At the end of the study respiratory, the anti-inflammatory and antioxidative effects of nebivolol were assessed. The asthmatic group exhibited a significant increase in early and late airway resistance, airway hyperreactivity to histamine, total and absolute leucocytic count, tumor necrosis factor-α, and interleukin-6 in bronchoalveolar lavage fluid and lung lipid peroxidation and a significant decrease in superoxide dismutase and glutathione compared to the control group. Additionally, there was a significant decrease in lung endothelial nitric oxide synthase (eNOS) and a significant increase in inducible nitric oxide synthase (iNOS) mRNA expression compared to the control group. The high dose of nebivolol counteracted the increased airway resistance induced by OVA, whereas it had no effect on airway hyperresponsiveness. Moreover, nebivolol exhibited significant anti-inflammatory and antioxidant effects and restored the altered levels of eNOS and iNOS compared to the asthmatic group. Collectively, these results suggest a beneficial effect of nebivolol in asthma.

Abstract
The concomitant presence of systemic arterial hypertension and chronic obstructive pulmonary disease (COPD) is frequent. Indeed, arterial hypertension is the most common comorbid disease in COPD patients. Since many antihypertensive drugs can act on airway function the treatment of arterial hypertension in COPD patients appears complex. Moreover, in these patients, a combined therapy is required for the adequate control of blood pressure. Currently, available data are inconsistent and not always comparable. Therefore the aim of this review is to analyze how antihypertensive drugs can affect airway function in order to improve the clinical management of hypertensive patients with COPD. Thiazide diuretics and calcium channel blockers appear the first-choice pharmacological treatment for these patients.

Abstract
Perioperative hypertension is a common problem. If hypertension is left untreated in patients at risk, infarctions and stroke are possible. There are limited choices of antihypertensive agents for the office. Aggressive antihypertensive therapy is not indicated because most of the episodes seen in the office are hypertensive urgencies and not emergencies. Hypotension is usually managed by decreasing the depth of anesthesia, intravenous fluids, and then vasopressors, typically ephedrine or phenylephrine. Consider treatment of hypotension whenever the mean arterial pressure decreases less than 60 mm Hg.

Abstract
Bronchodilators are central in the treatment of of airways disorders. They are the mainstay of the current management of chronic obstructive pulmonary disease (COPD) and are critical in the symptomatic management of asthma, although controversies around the use of these drugs remain. Bronchodilators work through their direct relaxation effect on airway smooth muscle cells. at present, three major classes of bronchodilators, β(2)-adrenoceptor (AR) agonists, muscarinic receptor antagonists, and xanthines are available and can be used individually or in combination. The use of the inhaled route is currently preferred to minimize systemic effects. Fast- and short-acting agents are best used for rescue of symptoms, whereas long-acting agents are best used for maintenance therapy. It has proven difficult to discover novel classes of bronchodilator drugs, although potential new targets are emerging. Consequently, the logical approach has been to improve the existing bronchodilators, although several novel broncholytic classes are under development. An important step in simplifying asthma and COPD management and improving adherence with prescribed therapy is to reduce the dose frequency to the minimum necessary to maintain disease control. Therefore, the incorporation of once-daily dose administration is an important strategy to improve adherence. Several once-daily β(2)-AR agonists or ultra-long-acting β(2)-AR-agonists (LABAs), such as indacaterol, olodaterol, and vilanterol, are already in the market or under development for the treatment of COPD and asthma, but current recommendations suggest the use of LABAs only in combination with an inhaled corticosteroid. In addition, some new potentially long-acting antimuscarinic agents, such as glycopyrronium bromide (NVA-237), aclidinium bromide, and umeclidinium bromide (GSK573719), are under development, as well as combinations of several classes of long-acting bronchodilator drugs, in an attempt to simplify treatment regimens as much as possible. This review will describe the pharmacology and therapeutics of old, new, and emerging classes of bronchodilator.

Abstract
We still do not know whether the successful treatment of the comorbid diseases associated with COPD, mainly cardiovascular disease, also positively influences the course of the lung disease because so far there are few definite data documenting that treatment of COPD comorbidities will reduce morbidity and mortality rates in these patients. Observational studies suggest that COPD patients treated with statins, angiotensin-converting enzyme inhibitors and angiotensin II type 1 receptor blockers, and β-adrenoceptor blockers may have improved survival and reduced hospitalisation from exacerbations. Progress in basic and translational research has led to a better understanding of pharmacological mechanisms that may explain the effects of these drugs on COPD and some small clinical trial activity is beginning to generate promising results.

Abstract
Accelerated sinus rhythm is an important side effect of inhaled salbutamol which is especially harmful in patients with chronic obstructive pulmonary disease (COPD) and coronary heart disease (CHD). Cross-over, randomized, open label study design. 20 patients (18 males and two females) with COPD stage II-IV and comorbide CHD NYHA class I-III were included. Spirometry with 400 mg salbutamol inhalation was performed at two consecutive days of the study. Patients in group I were prescribed 5 mg ivabradine per os 3 h before salbutamol inhalation solely on the first day of the study and patients of group II received 5 mg ivabradine only on the second day of the study. Salbutamol caused a significant increase of HR by 5.5 bpm (95% CI 0.8; 10.2, p < 0.03). After ivabradine ingestion salbutamol did not change HR significantly by -2.4 bpm (-7.0; 2.3, p = 0.33). The attenuation of HR elevation by ivabradine was significant, p < 0.01. Salbutamol alone increased FEV1 by 6.0% (2.7; 9.3, p < 0.01). This effect was not impaired by ivabradine (FEV1 increase by 7.7% (2.8; 12.6, p < 0.01 versus baseline, p = 0.5 versus no ivabradine). Ivabradine 5 mg per os prevents heart rate acceleration after inhalation of 400 mg salbutamol. Ivabradine has no impact on lung function in patients with moderate-to-very-severe COPD and CHD comorbidity.

Abstract
Although its clinical use in Europe dates almost 10 years, nebivolol is a beta-blocker that has been only recently introduced in the U.S. market. Like carvedilol, nebivolol belongs to the third generation of beta-blockers, which possess direct vasodilator properties in addition to their adrenergic blocking characteristics. Nebivolol has the highest beta(1)-receptor affinity among beta-blockers and, most interestingly, it substantially improves endothelial dysfunction via its strong stimulatory effects on the activity of the endothelial nitric oxide synthase and via its antioxidative properties. Because impaired endothelial activity is attributed a major causal role in the pathophysiology of hypertension, coronary artery disease, and congestive heart failure, the endothelium-agonistic properties of nebivolol suggest that this drug might provide additional benefit beyond beta-receptor blockade. Although lesser beta-blocker-related side effects have been reported in patients with chronic obstructive pulmonary disease or impotence taking nebivolol, side effects and contraindications overlap those of other beta-blockers. Clinically, this compound has been proven to have antihypertensive and anti-ischemic effects as well as beneficial effects on hemodynamics and prognosis in patients with chronic congestive heart failure. Further studies are now necessary to compare the benefit of nebivolol with that of other drugs in the same class and, most importantly, its prognostic impact in patients with hypertension.

Abstract
Elderly patients are increasingly referred for complex surgery, but are at particular risk for coronary artery disease. One strategy to prevent perioperative cardiac events in elderly patients is to employ perioperative beta-blockade, but doing so has the potential to increase the incidence of congestive heart failure, perioperative hypotension, bradycardia, and stroke. This article examines common comorbidities in the elderly who may benefit from the chronic use of beta-blockers, prophylactic perioperative use of beta-blockers including timing, dosage, and choice of beta-blocker, the pharmacologic effects of aging, and recommendations on the use of beta-blockers.

Abstract
Despite progress in recent years in the prevention, detection, and treatment of high blood pressure (BP), hypertension remains an important public health challenge. Hypertension affects approximately 1 billion individuals worldwide. High BP is associated with an increased risk of mortality and morbidity from stroke, coronary heart disease, congestive heart failure, and end-stage renal disease; it also has a negative impact on the quality of life. Hypertension cannot be eliminated because there are no vaccines to prevent the development of hypertension, but, its incidence can be decreased by reducing the risk factors for its development, which include obesity, high dietary intake of fat and sodium and low intake of potassium, physical inactivity, smoking, and excessive alcohol intake. For established hypertension, efforts are to be directed to control BP by lifestyle modification (LSM). However, if BP cannot be adequately controlled with LSM, then pharmacotherapy can be instituted along with LSM. Normalization of BP reduces cardiovascular risk (for cardiovascular death, myocardial infarction, and cardiac arrest), provides renoprotection (prevention of the onset or slowing of proteinuria and progression of renal dysfunction to end-stage renal disease in patients with hypertension, diabetes mellitus types 1 and 2, and chronic renal disease), and decreases the risk of cerebrovascular events (stroke and cognition impairment), as has been amply demonstrated by a large number of randomized clinical trials. In spite of the availability of more than 75 antihypertensive agents in 9 classes, BP control in the general population is at best inadequate. Therefore, antihypertensive therapy in the future or near future should be directed toward improving BP control in treated hypertensive patients with the available drugs by using the right combinations at optimum doses, individually tailored gene-polymorphism directed therapy, or development of new modalities such as gene therapy and vaccines. Several studies have shown that BP can be reduced by lifestyle/behavior modification. Although, the reductions appear to be trivial, even small reductions in systolic BP (for example, 3-5 mm Hg) produce dramatic reduction in adverse cardiac events and stroke. On the basis of the results of clinical and clinical/observational studies, it has been recommended that more emphasis be placed on lifestyle/behavior modification (obesity, high dietary intake of fat and sodium, physical inactivity, smoking, excessive alcohol intake, low dietary potassium intake) to control BP and also to improve the efficacy of pharmacologic treatment of high BP. New classes of antihypertensive drugs and new compounds in the established drug classes are likely to widen the armamentarium available to combat hypertension. These include the aldosterone receptor blockers, vasodilator beta-blockers, renin inhibitors, endothelin receptor antagonists, and dual endopeptidase inhibitors. The use of fixed-dose combination drug therapy is likely to increase. There is a conceptual possibility that gene therapy may yield long-lasting antihypertensive effects by influencing the genes associated with hypertension. But, the treatment of human essential hypertension requires sustained over-expression of genes. Some of the challenging tasks for successful gene therapy that need to be mastered include identification of target genes, ideal gene transfer vector, precise delivery of genes into the required site (target), efficient transfer of genes into the cells of the target, and prompt assessment of gene expression over time. Targeting the RAS by antisense gene therapy appears to be a viable strategy for the long-term control of hypertension. Several problems that are encountered in the delivery of gene therapy include 1) low efficiency for gene transfer into vascular cells; 2) a lack of selectivity; 3) problem in determining how to prolong and control transgene expression or antisense inhibition; and 4) difficulty in minimizing the adverse effects of viral or nonviral vectors. In spite of the hurdles that face gene therapy administration in humans, studies in animals indicate that gene therapy may be feasible in treating human hypertension, albeit not in the near future. DNA testing for genetic polymorphism and determining the genotype of a patient may predict response to a certain class of antihypertensive agent and thus optimize therapy in individual patients. In this regard, there are some studies that report the effectiveness of antihypertensive therapy based upon the genotype of selected patients. Treatment of human hypertension with vaccines is feasible but is not likely to be available in the near future.

STUDY OBJECTIVES To determine whether an association exists between health care resource use and beta-blocker therapy in patients with asthma or chronic obstructive pulmonary disease (COPD), and to determine whether any significant differences exist between type of beta-blocker agent administered and resource use. DESIGN Retrospective cohort study. DATA SOURCE Three Veterans Administration (VA) databases with information from hospitals and clinics in Iowa and Nebraska. Patients. A total of 8390 veterans with a diagnosis of asthma or COPD receiving treatment with a beta-blocker or another cardiovascular agent. MEASUREMENTS AND MAIN RESULTS Clinic visits and hospital admissions for asthma or COPD that occurred in 2000-2001 were identified using electronic administrative data files. Analyses were adjusted for comorbidity and patient demographics. Mean patient age was 67 years, and 97% of the patients were men. In unadjusted analyses, patients taking beta-blockers had more hospital admissions, similar inpatient length of stay (LOS), and fewer outpatient clinic visits for asthma or COPD. In adjusted analyses, however, no difference was noted in the odds of hospital admission or in LOS, and patients had fewer clinic visits related to asthma or COPD. The hazard ratio for hospital admission for asthma or COPD during the observation year was similar for patients taking and not taking beta-blockers, and no difference was noted with selective versus nonselective beta-blockers. However, the hospital admission rate was lower with atenolol than metoprolol. CONCLUSION Patients taking beta-blockers did not have more hospital admissions or clinic visits for their asthma or COPD than patients not taking these agents. When clinically indicated, beta-blockers-especially atenolol-should be considered for patients with asthma or COPD.

Abstract
Adequate control of blood pressure poses challenges for hypertensive patients and their physicians. Success rates of greater than 80% in reducing blood pressure to target values among high-risk hypertensive patients reported by several recent clinical trials argue that effective medications currently are available. Yet, only 34% of hypertensive patients in the United States are at their goal blood pressure according to the most recent national survey. Rational selection of antihypertensive drugs that target both the patient's blood pressure and comorbid conditions coupled with more frequent use of low-dose drug combinations that have additive efficacy and low adverse-effect profiles could improve significantly US blood pressure control rates and have a positive impact on hypertension-related cardiovascular and renal mortality and morbidity. This article reviews the pharmacokinetic and pharmacodynamic principles that underlie the actions of drugs in each of the classes of antihypertensive agents when used alone and in combination, provides practical pharmacologic information about the drugs most frequently prescribed for treatment of hypertension in the outpatient setting, and summarizes the current data influencing the selection of drugs that might be used most effectively in combination for the majority of hypertensive patients whose blood pressures are not controlled adequately by single-drug therapy.

Abstract
BACKGROUND Heart failure is a widespread and costly malady. It represents the leading single diagnosis for hospitalized patients. For many heart failure patients, angiotensin-converting enzyme (ACE) inhibitors are either not tolerated or contraindicated, but angiotensin receptor blockers such as valsartan may be a therapeutic option for them. OBJECTIVE The aim of this study was to prepare a budget impact analysis to assist health plans in evaluating the financial impact of adding valsartan therapy to usual care for heart failure patients not receiving ACE inhibitors. METHODS A budget impact analysis was developed for a hypothetical US health plan. Model inputs included demographic data, estimates of the prevalence of heart failure and proportion of heart-failure patients not on ACE inhibitors, prevalence of heart failure-related hospitalization, cost data, and resultant health care utilization from the Valsartan Heart Failure Trial (Val-HeFT). Costs and cost savings were reported as year-2001 US dollars. RESULTS An estimated 1207 of hypothetical 250,000 enrollees were projected to have heart-failure diagnoses, with 603 (50.0%) not receiving ACE inhibitors, and 160 (26.5%) of such patients being hospitalized each year. For valsartan-treated patients, savings due to reduced hospitalizations and shorter length of hospital stay were 1,083,938 US dollars and 221,364 US dollars, respectively. Subtracting the cost of valsartan treatment (629,472 US dollars) from savings yielded projected net savings of 675,830 US dollars per year. Varying patient, treatment, and payer-mix characteristics resulted in projected net savings of $409,598 to 1,350,617 US dollars per year. CONCLUSIONS Addition of valsartan therapy to usual care in this model analysis resulted in net cost savings among hypothetical heart-failure patients not receiving ACE inhibitors. Substantial cost savings were realized, regardless of variation in model parameters.

Abstract
INTRODUCTION beta-Blockers are known to worsen FEV(1) and airway hyperresponsiveness (AHR) in patients with asthma. Both characteristics determine the outcome of COPD, a disease with frequent cardiac comorbidity requiring beta-blocker treatment. OBJECTIVE To determine the effects of beta-blockers on AHR (provocative concentration of methacholine causing a 20% fall in FEV(1) [PC(20)]), FEV(1), and response to formoterol in patients with COPD. DESIGN A double-blind, placebo-controlled, randomized, cross-over study. SETTING An ambulatory, hospital outpatient clinic of pulmonary diseases. PATIENTS Patients with mild-to-moderate irreversible COPD and AHR. INTERVENTION Fifteen patients received propranolol (80 mg), metoprolol (100 mg), celiprolol (200 mg), or placebo for 4 days, followed by a washout period >/= 3 days. On day 4 of treatment, FEV(1) and PC(20) were assessed. Immediately hereafter, formoterol (12 microg) was administered and FEV(1) was measured for up to 30 min. RESULTS PC(20) was significantly lower (p < 0.01) with propranolol and metoprolol treatment (geometric means, 2.06 mg/mL and 2.02 mg/mL, respectively) than with placebo (3.16 mg/mL) or celiprolol (3.41 mg/mL). FEV(1) deteriorated only after propranolol treatment (2.08 +/- 0.31 L) [mean +/- SD] compared with placebo (2.24 +/- 0.37 L). The fast bronchodilating effect of formoterol was hampered by propranolol (mean increase in FEV(1) at 3 min, 6.7 +/- 8.9%) but was unaffected by the other beta-blockers (16.9 +/- 9.8%, 22 +/- 11.6%, and 16.9 +/- 9.0% for placebo, metoprolol, and celiprolol, respectively). CONCLUSIONS Pulmonary effects did not occur by celiprolol. Only propranolol reduced FEV(1) and the bronchodilating effect of formoterol. Both metoprolol and propranolol increased AHR. Thus, different classes of beta-blockers have different pulmonary effects. The anticipated beneficial cardiovascular effects of a beta-blocker must be weighted against the putative detrimental pulmonary effects, ie, effect on FEV(1), AHR, and response to additional beta(2)-agonists.

Abstract
beta-Adrenoceptor blocking agents (beta-blockers) have been established as therapeutics for treatment of patients with hypertension, ischemic heart diseases, chronic heart failure, arrhythmias, and glaucoma. However, their clinical use is limited because some patients are adversely affected by their side effects. The discovery of cardioselective (beta(1)-selective) blockers has overcome some of the problems. Current retrospective studies have revealed that vasodilating beta-blockers (so-called beta-blockers of the third generation) have advantages over the conventional type of beta-blockers in terms of minimizing the adverse effects and improving the disease-derived dysfunction, thus enhancing the quality of life variables. Some of the possible advantages include improvement of insulin resistance, decrease in low-density lipoprotein cholesterol in association with increase in high-density lipoprotein cholesterol, attenuation of bronchial asthma attack and respiratory dysfunction, alleviation of coronary vasospasm provocation, peripheral circulatory disturbances, and erectile dysfunction, and better patient compliance. Release of nitric oxide, antioxidant action, beta(2)-adrenoceptor activation, Ca(2+) entry blockade, and other mechanisms underlying the vasodilating action may be responsible for the beneficial therapeutic effects of these agents.

Respiration 2004; 71:159-64.

Abstract
BACKGROUND It has been suggested that the antihypertensive agent nebivolol, a beta1-adrenoceptor-blocking agent that modulates the endogenous production of nitric oxide, is preferable to 'conventional' beta1-blockers in hypertensive patients with airway dysfunction. OBJECTIVES Since beta1-blockade by nebivolol is larger after repeated dosing than after a single oral intake, we have explored its effect on pulmonary function after a 2-week treatment in hypertensive patients with mild to moderate COPD. METHODS A single-blind crossover design was used. Twenty patients with COPD as selected above and with a diastolic blood pressure of 95-110 mm Hg after 1 week of placebo run-in were entered into the two 2-week active treatment periods with either 5 mg nebivolol (n = 10) or 30 mg nifedipine gastrointestinal-transport-system (GITS) (n = 10) taken for a period of 2 weeks. After a further 1-week washout, subjects were crossed-over to receive the other drug for 2 additional weeks. At each visit, changes in spirometric indexes and the interaction with the bronchodilator effect of salbutamol were investigated. Moreover, systolic and diastolic blood pressure (BP) together with heart rate were manually measured in order to evaluate the cardiovascular effects of the different treatments. Throughout the study, patients recorded symptoms. RESULTS Similar and significant reductions in systolic and diastolic BP were observed with both treatments. The impact of nifedipine on FEV1 was not significant (p > 0.05), while that of nebivolol was slight. The maximum response to salbutamol was slightly decreased with either nebivolol or nifedipine GITS. Day-to-day airway obstruction control, interpreted from patient recordings of symptom scores and inhaler use, was similar with both treatments. CONCLUSIONS Our pilot study suggests that the use of nebivolol in hypertensive patients with stable mild to moderate COPD was safe during a 2-week trial. Evaluation of longer time periods, larger patient numbers with more severe COPD or during exacerbations is warranted.
