Flecainide acetate (Tambocor), the acetate salt form of flecainide, is a potent class Ic antiarrhythmic drug used in managing certain situations to prevent serious heart rhythm disorders or supraventricular arrhythmia. It works by blocking Nav1.5 sodium channels, which play a major part in the heart's electrical activity, thus causing prolongation of the cardiac action potential. When the heart is firing too quickly in an abnormal rhythm (arrhythmia), flecainide slows down the electricity to help the rhythm return to normal.
