A class Ic antiarrhythmic agent used to prevent and treat tachyarrhythmias, works by blocking the Nav1.5 sodium channel in the heart.

A class Ic antiarrhythmic agent used to prevent and treat tachyarrhythmias, works by blocking the Nav1.5 sodium channel in the heart, slowing the upstroke of the cardiac action potential; also inhibits ryanodine receptor 2 (RyR2), reduces calcium sparks and thus arrhythmogenic calcium waves in the heart.Heart Arrhythmia Approved(In Vitro):Flecainide is a class 1C antiarrhythmic drug especially used for the management of supraventricular arrhythmia. Flecainide works by blocking the Nav1.5 sodium channel in the heart, causing prolongation of the cardiac action potential. in vitro: Under the current-clamp condition, flecainide (1-100 microM) prolonged the action potential duration at both the early and the late phases of repolarization in a concentration-dependent manner without affecting the resting membrane potential . At a holding potential (HP) of -120 mV, flecainide use-dependently blocked WT and G1306E I(Na) equally but was more potent on R1448C channels. For WT, the extent of block depended on a holding voltage more negative than the activation threshold, being greater at -90 mV as compared to -120 and -180 mV . in vivo: Flecainide (80-130 mg/m(2) orally) resulted in termination of the tachycardia in all 8 patients. Acute pharmacological termination of arrhythmia occurred with oral flecainide loading in 1 and temporarily with intravenous esmolol loading in 1 patient.
