Beta-blockers shouldn’t be prescribed to patients without any indication for them. ); the Ann Arbor VA Medical Center (J.L.C.) ), NYP–Queens Medical Center (A.S.), and NYP–Brooklyn Methodist Medical Center (J.A.W.) Simvastatin for the prevention of exacerbations in moderate-to-severe COPD. For example, a few weeks ago, I made an argument that for CRASH-3 the secondary endpoints might be considered positive. The same applied to COPD (HR 0.88; 95% CI 0.75 to 1.05, p = 0.177), DM (HR 0.95; 95% CI 0.82 to 1.10, p = 0.485), hypoglycemia (HR 0.88; 95% CI 0.47 to 1.67, p = 0.707), and RF (HR 1.25; 95% CI 0.93 to 1.69, p = 0.142) hospitalizations. Mahler DA, Wells CK. For Recent evidence suggests that using cardio-selective beta-blockers in COPD … The metoprolol group also had a greater increase in SOBQ scores from baseline, indicating a worsening in shortness of breath. Suissa S, Ernst P. Beta-blockers in COPD: a methodological review of the observational studies. BMJ Open 2016;6(6):e012292-e012292. Exacerbations of Chronic Obstructive Pulmonary Disease (COPD). The most common reasons for exclusion were not meeting the spirometric criteria for COPD or a resting heart rate that was out of the mandated range. COPD patients could also be included (code H3) if they have high reversibility. Adjusted models included the covariates of race, sex, baseline age, FEV1 as a percentage of the predicted value, smoking status, heart rate greater than the median value, number of hospitalizations for COPD during the previous year, number of exacerbations treated with glucocorticoids or antibiotics during the previous year, use of supplemental oxygen, scores on the COPD Assessment Test and the mMRC scale, and trial center. Which Genes for Hereditary Breast Cancer? Thorax 2016;71:8-14. 5 mg of Metoprolol and 10 mg Amlodipine for about 3 months. 26. Metoprolol zählt jedoch neben Bisoprolol, Nebivolol und Atenolol zu den selektiven Betablockern, welche nur am Herzen wirken: Damit ist der Wirkstoff auch für Asthma- und COPD-Patienten mit Herz-Kreislauf-Erkrankungen geeignet. We used Student’s t-tests to compare annualized rates of hospitalization and nonfatal serious adverse events and used mixed-effects models with patient-specific random intercepts to compare between-group differences in changes in continuous measures of secondary end points. § Scores for dyspnea on the modified Medical Research Council scale range from 0 to 4, with higher scores indicating more severe breathlessness. Am J Respir Crit Care Med 2017;195:557-582. This finding could explain why the effects of the cardioselective β-blocker metoprolol on AHR are the same as those of the nonselective β-blocker propranolol in patients with COPD . interpretation is that any study with a negative primary endpoint is negative, Metoprolol for the Prevention of Acute Exacerbations of COPD Among patients with moderate or severe COPD who did not have an established indication for beta-blocker use, the time until the first COPD exacerbation was similar in the metoprolol group and the placebo group. It seems unlikely that the risks of worsening asthma or COPD outweigh the potential benefits of beta blocker use, in these patients. The most effective and engaging way for clinicians to learn, improve their practice, and prepare for board exams. The starting dose was one 50-mg tablet of metoprolol or matching placebo taken orally daily. The patients in the metoprolol group had a greater increase (indicating worse control) from baseline in the score on the COPD Assessment Test than those in the placebo group, with a difference of 1.13 points (95% CI, 0.06 to 2.20) at day 112 and a difference of 1.47 points (95% CI, 0.32 to 2.62) at day 336 (Fig. Information and tools for librarians about site license offerings. Jetzt kommt eine aktuelle Studie zu dem Ergebnis, dass die Therapie mit Betablockern auch bei Patienten mit schwerer COPD, die wegen ihrer starken Atemwegsverengung bereits auf eine tägliche Sauerstoff-Behandlung angewiesen sind, sicher und zugleich von Vorteil ist, zumal sich dadurch auch die Häufigkeit von Verschlechterungsschüben (Exazerbationen) bei den Patienten reduzieren … Lancet Respir Med 2014;2:195-203. The result of the subgroup analysis of the risk of exacerbation is provided in Figure S2. The hypothesis was based on non-causal associations of better outcome among patients who used beta-blockers, which, as usual, were then subject to further hypothetical pathophysiological explanations. Buy Metoprolol in Des Moines; Buy Metoprolol in ME; Price Metoprolol in Orlando; Price Metoprolol from CO; Buy Metoprolol in Minneapolis; Introduction. Spirometric reference values from a sample of the general U.S. population. Panel B shows the probability of freedom from either a severe exacerbation (leading to hospitalization) or a very severe exacerbation (leading to hospitalization with intubation and mechanical ventilation). Chest 2007;132:456-463. See. No commercial entity was involved in the trial. The trial protocol, which was approved by the data and safety monitoring committee and the institutional review board at each trial center, is available with the full text of this article at NEJM.org. The content of this site is intended for health care professionals. Effects of controlled-release metoprolol on total mortality, hospitalizations, and well-being in patients with heart failure: the Metoprolol CR/XL Randomized Intervention Trial in congestive heart failure (MERIT-HF). We need to stop overinterpreting non-causal associations. Chest 2005;127:818-824. The rate of overall nonfatal serious adverse events was 0.65 per person-year in the metoprolol group and 0.43 per person-year in the placebo group. Third, in part because the trial was stopped early, we had limited power to detect differences in the risk of severe exacerbation between subgroups and could not identify specific factors that predisposed patients to adverse outcomes when treated with metoprolol. There There was no significant between-group difference in the median time until the first exacerbation, which was 202 days (95% confidence interval [CI], 162 to 282) in the metoprolol group and 222 days (95% CI, 189 to 295) in the placebo group (. PLoS One 2014;9(11):e113048-e113048. the study protocol (published at clinicaltrials.gov) the following endpoints are Metoprolol was purchased for use in the trial; matching placebo was manufactured at the Current Good Manufacturing Practices Facility at the Temple University School of Pharmacy. Common Questions and Answers about Metoprolol copd. NEW! β-Blockers are associated with a reduction in COPD exacerbations. Minimum clinically important difference for the COPD Assessment Test: a prospective analysis. 16. The study was stopped prematurely, due largely to futility. Third, in part because the trial was stopped early, we had limited power to detect differences in the risk of severe exacerbation between subgroups and could not identify specific factors that predisposed patients to adverse outcomes when treated with metoprolol. 3. Case Records of the Massachusetts General Hospital, Who Goes First? Sample-size calculations that included a two-sided alpha level of 0.05 and a trial power of 90% indicated we would need to enroll 1028 patients on the assumption of a loss to follow-up of approximately 12%. 12. The discontinuation of metoprolol or placebo occurred more frequently in the metoprolol group than in the placebo group (11.2% vs. 6.1%). β-Blockers after acute myocardial infarction in patients with chronic obstructive pulmonary disease: a nationwide population-based observational study. listed: So, We observed no evidence of between-group differences in the frequency of patient-reported adverse events that were potentially related to metoprolol (Table S3). Niewoehner DE, Lokhnygina Y, Rice K, et al. The majority of deaths in the metoprolol group were attributed to COPD (7, vs. 1 in the placebo group) (Table 3). No effect on lung function was observed in the metoprolol group. likelihood that the trial could possibly show benefit from metoprolol) and some concerns regarding safety. If beta-blocker therapy is necessary in thes… 7. incidence of COPD exacerbation. 35.

In a randomized, double-blind, crossover trial, 40 CAD patients with mild COPD and significant reversibility received either bisoprolol 5 mg or atenolol 50 mg [ 84 ]. As discussed earlier, premature termination increases the likelihood of obtaining spurious results due to transient statistical fluctuations. Cardiovascular disease is a frequent comorbidity in patients with COPD. 36. van der Woude HJ, Zaagsma J, Postma DS, Winter TH, van Hulst M, Aalbers R. Detrimental effects of beta-blockers in COPD: a concern for nonselective beta-blockers. ); the Cincinnati VA Medical Center, Cincinnati (R.J.P. All the patients had a clinical history of COPD, along with moderate airflow limitation and an increased risk of exacerbations, as evidenced by a history of exacerbations during the previous year or the prescribed use of supplemental oxygen. Global Strategy for the Diagnosis, Management, and Prevention of Chronic Obstructive Lung Disease 2017 Report: GOLD executive summary. We enrolled patients between the ages of 40 and 85 years who had received a clinical diagnosis of COPD and who had at least moderate airflow limitation, as defined by the Global Initiative for Obstructive Lung Disease (GOLD),2 as follows: a forced expiratory volume in 1 second (FEV1) of less than 80% of the predicted value after bronchodilation and a ratio of the FEV1 to the forced vital capacity (FVC) of less than 0.70. Global, regional, and national age-sex-specific mortality for 282 causes of death in 195 countries and territories, 1980-2017: a systematic analysis for the Global Burden of Disease Study 2017. S7). 19. Es leite sich zwangsläufig die Empfehlung ab, keine Patienten mit Metoprolol zu behandeln, bei denen hierfür keine eindeutige Indikation bestehe, und insbesondere keine Hochrisiko-COPD-Patienten. mortality or all-cause hospitalization. During the treatment period, there were 11 deaths in the metoprolol group and 5 in the placebo group, with unadjusted and adjusted hazard ratios for death of 2.18 (95% CI, 0.76 to 6.29) and 2.13 (95% CI, 0.69 to 6.42), respectively (Fig. Key secondary end points included the rate of COPD exacerbations, all-cause mortality, all-cause hospitalization, results of spirometry, distance on the 6-minute walk test, dyspnea assessments, and measures of quality of life. Yancy CW, Jessup M, Bozkurt B, et al. 27. pre-specified endpoint). (Details regarding the power analyses are provided in the Supplementary Appendix, available at NEJM.org.) COPD and Beta-blockers: another myth dispensed…, IBCC chapter – Disseminated Intravascular Coagulation (DIC), PulmCrit- RCTs don't justify using convalescent plasma or antibody cocktails. Azithromycin for prevention of exacerbations of COPD. A primary concern about the use of beta-blockers in patients with COPD is that the drugs may cause a worsening in lung function. Divo M, Cote C, de Torres JP, et al. The use of beta-blockers in COPD has been subject to repeated reversals over the past few decades. For fatal adverse events, the P value for the overall between-group comparison was calculated by the log-rank test; P=0.17 by Fisher’s exact test for the overall comparison among the causes of death. Insbesondere bei höheren Dosierungen haben sie aber ebenfalls einen hemmenden Einfluss auf β 2-Rezeptoren. Meguro M, Barley EA, Spencer S, Jones PW. The rate of hospitalization for any cause was 0.66 per person-year (95% CI, 0.47 to 0.86) in the metoprolol group and 0.42 per person-year (95% CI, 0.30 to 0.55) in the placebo group. I’m surprised that you didn’t mention the higher rate of active smokers in the Metoprolol group (35% vs 27%), which is known to result in more and more severe COPD exacerbations. Number of hospital admissions for COPD over a year, Number of hospital days due to COPD exacerbations over a year, Major adverse coronary events (MACE) over a year, Incidence of presumed metoprolol side-effects, Modified Medical Research Council dyspnea scale, Forced expiratory volume in one second (FEV1), Exercise capacity in six minutes (six-minute walk distance), San Diego Shortness of Breath Questionnaire, Combined rate of acute exacerbations of COPD and major adverse coronary events (MACE). Some beta-adrenergic receptor blocking agents (i.e., beta-blockers) are contraindicated in patients with bronchial asthma or with a history of bronchial asthma, or severe chronic obstructive pulmonary disease. Chest 1988;93:580-586. Observational studies suggest that beta-blockers may reduce the risk of exacerbations and death in patients with moderate or severe chronic obstructive pulmonary disease (COPD), but these findings have not been confirmed in randomized trials. Nonfatal and Fatal Serious Adverse Events. The most common reason for discontinuation was an increase in respiratory symptoms (Table S4). My preference is to use some judgement in these studies, based on numerous factors (e.g. Valuable tools for building a rewarding career in health care. Criner GJ, Connett JE, Aaron SD, et al. In several large clinical trials, metoprolol succinate, carvedilol, and bisoprolol have demonstrated a reduction in morbidity and mortality in patients with systolic HF when added to baseline angiotensin‐converting enzyme (ACE) inhibitor therapy. Patients in the metoprolol group may have been sicker (with a substantially higher rate of COPD exacerbation in the year. Su TH, Chang SH, Kuo CF, Liu PH, Chan YL. Fourth, we do not know whether these results would be similar for other cardioselective beta-blockers or for noncardioselective agents, although concern regarding adverse respiratory effects is greater with the latter. spirometry • If attempting this audit in your own practice it might be worth considering if there are any patients who should no longer be classified as having asthma. Second, our trial population had moderate or severe COPD with a high prevalence of supplemental oxygen use and previous hospitalization for COPD. Stat Med 1994;13:1341-1356. Am J Respir Crit Care Med 2002;166:111-117. We did not observe this effect, and none was reported in a meta-analysis on the subject.35 We also found no evidence of between-group differences in the 6-minute walk distance or in patients’ reports of possible beta-blocker side effects. PulmCrit – Six RCTs to answer one question: what is the role of tocilizumab in COVID-19? However, looking at the totality of the subjective data, this may just represent statistical noise: The other difference was that patients in the metoprolol group had a higher rate of COPD-related hospitalization (defined below as a “severe” or “very severe” exacerbation of COPD): This Puts us back to where we were initially FJ, et al practice, Subscribe to the most common for..., angiotensin-converting enzyme inhibitors, and Birmingham Veterans Affairs ( VA ) Medical Center R....
