Beta Blocker Selection for Patients with COPD
Cardioselective beta blockers such as bisoprolol should be the first choice for patients with COPD who require beta blocker therapy, followed by metoprolol as a second option. 1
Recommended Beta Blockers for COPD Patients
When selecting a beta blocker for patients with COPD, cardioselectivity (beta-1 selectivity) is the key factor to consider:
| Beta Blocker | Beta-1 Selectivity | Recommendation for COPD |
|---|---|---|
| Bisoprolol | High | First choice |
| Metoprolol | Medium | Second choice |
| Atenolol | Medium | Alternative option |
| Nebivolol | High + vasodilatory | Consider in selected cases |
Why Cardioselectivity Matters
Cardioselective beta blockers preferentially block beta-1 receptors (found primarily in the heart) while having minimal effect on beta-2 receptors (found primarily in the lungs). This selectivity is crucial because:
- Non-selective beta blockers can cause bronchospasm in COPD patients by blocking beta-2 receptors in the airways 2
- Cardioselective agents like bisoprolol have demonstrated minimal effects on pulmonary function in patients with COPD 3, 4
- The European Society of Cardiology and other guideline societies support using cardioselective beta blockers in patients with cardiovascular disease and concurrent COPD 1
Administration Guidelines
When initiating beta blockers in COPD patients:
- Start with the lowest effective dose of a cardioselective beta blocker and titrate slowly while monitoring respiratory function 1
- Consider pulmonary function testing before and after initiation
- Monitor closely for signs of airway obstruction (wheezing, shortness of breath)
- Avoid abrupt discontinuation as this can lead to rebound cardiovascular effects 5, 6
- Consider administering in smaller doses three times daily instead of larger doses twice daily to avoid higher plasma levels 5
Beta Blockers to Avoid in COPD
- Non-selective beta blockers like propranolol should be avoided in all patients with COPD 1
- Carvedilol, which blocks β2 and α1 receptors, should be avoided despite its benefits in heart failure 1, 7
Evidence Supporting Cardioselective Beta Blockers in COPD
Recent evidence suggests that cardioselective beta blockers are better tolerated than previously thought in COPD patients:
- A Cochrane review found that cardioselective beta blockers did not produce a significant short-term reduction in airway function or increase in COPD exacerbations 8
- Studies have shown that in COPD patients with concurrent cardiovascular disease, the benefits of cardioselective beta blockers outweigh the potential respiratory risks 9, 10
- In a randomized crossover trial comparing different beta blockers in patients with heart failure and COPD, forced expiratory volume in 1 second (FEV1) was highest with bisoprolol and lowest with carvedilol, supporting the use of highly selective agents 7
Important Caveats
- Beta blockers should only be used in COPD patients when there is a clear cardiovascular indication 1, 10
- Recent studies suggest that beta blockers should not be used in COPD patients without overt cardiovascular disease, as they may increase the risk of COPD-related hospitalization 10
- Beta blockers should not be initiated during acute COPD exacerbations 1
Remember that while beta blockers have traditionally been considered contraindicated in COPD, current evidence supports the careful use of cardioselective agents when cardiovascular indications are present, with bisoprolol being the preferred first choice due to its high beta-1 selectivity.
