How does flecainide work in the body?
Flecainide is classified as a Class Ic antiarrhythmic agent [2]. It works by blocking sodium channels in the heart muscle cells. This action slows down the electrical conduction through the atria and ventricles, thereby helping to control abnormal heart rhythms [2].

Treatment for arrhythmias often depends on the specific type of irregular heartbeat and the individual patient's health status. Other antiarrhythmic medications, as well as lifestyle modifications or procedures like pacemakers or ablation, may be considered as alternatives or adjuncts to flecainide [2].
