Cardioselective beta-blockers for reversible airway disease

Cochrane Database Syst Rev. 2002:(4):CD002992. doi: 10.1002/14651858.CD002992.


Background: Beta-blocker therapy has mortality benefit in patients with hypertension, heart failure and coronary artery disease, as well as during the perioperative period. These drugs have traditionally been considered contraindicated in patients with reversible airway disease.

Objectives: To assess the effect of cardioselective beta-blockers in patients with asthma or COPD.

Search strategy: A search of EMBASE, MEDLINE and CINAHL was performed up to May 2002 using the terms: asthma*, bronchial hyperreactivity*, respiratory sounds*, wheez*, obstructive lung disease* or obstructive airway disease*, and adrenergic antagonist*, sympatholytic* or adrenergic receptor block*.

Selection criteria: Randomized, blinded, placebo-controlled trials of single dose or continued treatment of the effects of cardioselective beta-blockers in patients with reversible airway disease.

Data collection and analysis: Two independent reviewers extracted data from the selected articles, reconciling differences by consensus. Beta1-blockers were divided into those with or without intrinsic sympathomimetic activity (ISA). Interventions were: administration of single or continued beta1-blocker, and response to beta2-agonist given after the study drug.

Main results: Nineteen studies on single-dose treatment and 10 studies on continued treatment met the inclusion criteria. Single dose cardioselective beta-blocker produced a 7.46% (95% CI 5.59, 9.32) reduction in FEV1, but with a 4.63% (95% CI 2.47, 6.78) increase in FEV1 with beta2-agonist, compared to placebo. Treatment lasting 3 - 28 days produced no change in FEV1 (-0.42%; 95% CI -3.74, 2.91), symptoms or inhaler use, whilst maintaining a 8.74% (95% CI 1.96, 15.52) response to beta2-agonist. There was no significant change in FEV1 treatment effect for those patients with COPD: single doses -5.28% (95% CI -10.03, -0.54%), continued treatment 1.07% (CI -3.3, 5.44. With continued treatment there was no significant difference in FEV1 response for beta1-blockers without ISA compared to those with IS: -3.22% (96%CI -7.79, 1.36) compared to 2.72% (95% CI -2.12, 7.59). Those without ISA produced a 12.0% increase in FEV1 after beta2-agonist administration compared to placebo (95%CI 4.12,19.87) while beta1-blockers with ISA produced no change compared to placebo (-0.60% [95%CI -13.93, 12.73). These results were obtained in a small number od studies of few patients. The difference was not significant.

Reviewer's conclusions: Cardioselective beta-blockers given in mild - moderate reversible airway disease or COPD, do not produce adverse respiratory effects in the short term. Given their demonstrated benefit in conditions such as heart failure, cardiac arrhythmias and hypertension, these agents should not be withheld from such patients, but long term safety (especially their impact during an acute exacerbation) still needs to be established.
