Propafenone displays nonselective F1F1F1S1F1F1F10-blocking activity,and it generally should not be used to treat patients with asthma or bronchospastic disease because F1F1F1S1F1F1F10-blocking properties may inhibit bronchodilation.The highest concentrations of the drug are found in the lungs (10-fold higher than in the heart muscles or liver and 24-fold higher than in the kidneys).Albuterol is a F1F1F1S1F1F1F10 agonist.Lidocaine is used to treat ventricular arrhythmias.
