Why β-Blockers Can Trigger Asthma

In this video, we break down why β-blockers, commonly prescribed for high blood pressure, heart failure, arrhythmias, and angina, can trigger asthma attacks. Learn how β1 receptors in the heart and β2 receptors in the lungs work, why non-selective β-blockers like propranolol pose a risk, and how even cardioselective drugs like metoprolol or atenolol need caution. We’ll also explain why rescue inhalers (albuterol/salbutamol) may not work as well when a patient is on β-blockers, and what this means for safe prescribing in real life. Whether you’re a medical student, pharmacy student, healthcare professional, or just curious about pharmacology, this video will give you the clear, exam-ready explanation you need.
