Why is the use of non-selective beta-blockers (like Propranolol) contraindicated in patients using Beta-2 agonists for asthma?
Show answer and explanation
Correct answer: They cause severe bronchospasm via Beta-2 blockade
Beta-blockers that target Beta-2 receptors will directly compete with agonists like Albuterol. This prevents bronchodilation and can trigger a severe, sometimes fatal, asthma attack in susceptible individuals.
