Answer for screen readers
The final answer is Propranolol.
More Information
Propranolol is a non-selective beta-blocker widely known to potentially exacerbate asthma symptoms due to its action on both beta-1 and beta-2 receptors, leading to bronchoconstriction.
Tips
A common mistake is selecting cardio-selective beta-blockers like metoprolol or atenolol; they are less likely to cause asthmatic complications compared to non-selective ones like propranolol.
