Summary
Beta-blockers oppose the bronchodilating effect of indacaterol and can provoke bronchospasm in patients with airway disease. Penbutolol is non-selective, so the antagonism is more pronounced.
What this interaction means in plain words
Indacaterol and Penbutolol 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
Pharmacodynamic antagonism at beta-2 adrenergic receptors, blocking bronchodilation.
What to do
Avoid non-selective beta-blockers in patients with COPD or asthma who need indacaterol. If a beta-blocker is essential, switch to a cardioselective agent and monitor respiratory function.
What to ask your pharmacist
