Do beta-blockers affect lungs?
β-Blockers appear to reduce lung function in both the general population and those with COPD because they are poorly selective for cardiac β1-adrenoceptors over respiratory β2-adrenoceptors, and studies have shown that higher β-agonist doses are required to overcome the β-blockade.
Can metoprolol cause lung damage?
KEY TAKEAWAY: Metoprolol was associated with a higher risk of chronic obstructive lung disease (COPD) exacerbations leading to hospitalization and higher rate of very severe COPD exacerbation (requiring mechanical ventilation).

Metoprolol also affects cardiac output (reducing the volume of blood that is pumped by the heart) which can decrease the amount of oxygen in the body, leaving you short of breath.

At high doses, metoprolol also blocks beta-2 receptors within the lungs and airways (which may affect breathing).
