Propranolol and Salbutamol: Drug Interaction Guide
Quick answer: This is a major interaction — avoid combining Propranolol and Salbutamol unless specifically directed by your doctor.
How Propranolol interacts with Salbutamol
Propranolol non-selectively blocks β2-adrenergic receptors in bronchial smooth muscle, antagonising salbutamol bronchodilation and potentially precipitating bronchospasm in asthmatics.
What you should do
Avoid non-selective beta-blockers in patients with asthma or significant COPD; if a beta-blocker is required, use a cardioselective agent (bisoprolol, metoprolol) at the lowest effective dose.
