ABSTRACT
Introduction
Controversies regarding the use of beta-blocker in chronic obstructive pulmonary disease (COPD) have been longstanding and based on inconsistent data. COPD and cardiovascular disease have many shared risk factors and potentially overlapping pathophysiologic mechanisms. Beta-blockers, a mainstay of treatment in ischemic heart disease, congestive heart failure, and cardiac arrhythmia, remain underutilized in COPD patients despite considerable evidence of safety. Furthermore, observational studies indicated the potential benefits of beta-blockers in COPD via a variety of possible mechanisms. Recently, a randomized controlled trial of metoprolol versus placebo failed to show a reduction in COPD exacerbation risk in subjects with moderate to severe COPD and no absolute indication for beta-blocker use.
Areas covered
Physiology of beta-adrenergic receptors, links between COPD and cardiovascular disease, and the role of beta-blockers in COPD management are discussed.
Expert commentary
Beta-blockers should not be used to treat COPD patients who do not have conditions with clear guideline-directed recommendations for their use. Vigilance is recommended in prescribing these medications for indications where another drug class could be utilized.
Article highlights
Recognition and management of comorbidities in COPD are of paramount importance.
Beta-blockers are underutilized in COPD patients that have other indications for use including congestive heart failure, ischemic heart disease, and arrhythmias.
Cardioselective beta-blockers are preferable over non-cardioselective agents for use in COPD.
Chronic use of metoprolol should not be used as a COPD exacerbation risk reduction strategy in patients with COPD at high risk for exacerbation.
