Rationale:
🫁Nonselective beta-blockers antagonize β2-receptors in bronchial smooth muscle, risking bronchospasm and potentially life-threatening asthma exacerbations.

🫁Pre-existing asthma is thus a key contraindication/precaution when planning first-line beta-blocker therapy.
🫁Alternative first-line antihypertensives (e.g., thiazides, ACE inhibitors, ARBs, CCBs) are typically preferred absent compelling beta-blocker indications.
🫁If a beta-blocker is unavoidable, choose highly β1-selective at low doses with close monitoring.
