Summary
Nadolol blocks beta-2 receptors and can reduce or abolish the bronchodilator effect of inhaled epinephrine. Nonselective beta blockers may also provoke bronchospasm in asthma or COPD.
What this interaction means in plain words
Epinephrine inhaled and Nadolol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Competitive antagonism of beta-2 adrenergic receptors by nadolol.
What to do
Avoid nadolol in patients with asthma or reactive airway disease; use a cardioselective agent if a beta blocker is required. Monitor respiratory status closely if the combination is unavoidable.
