31. FLECAINIDE Class: Antiarrhythmic Agent, Class Ic Indications: Prevention and suppression of documented life-threatening ventricular arrhythmias (eg, sustained ventricular tachycardia); controlling symptomatic, disabling supraventricular tachycardias in patients without structural heart disease in whom other agents fai Flecainide is a synthetic agent derived from trifluoroethoxy-benzamide exhibiting antiarrhythmic and local anesthetic activity. As a class Ic antiarrhythmic that blocks sodium channels, flecainide depresses polarization phase 0 and decreases the induction velocity of the His-Purkinje system. It also decreases phase 4 slope and increases the depolarization threshold Flecainide is a Class IC anti-arrhythmic that is used in certain situations to prevent serious heart rhythm disorders. Flecainide may also be used for purposes not listed in this medication guide

Flecainide is a Class I anti-arrhythmic agent like encainide and propafenone. 7 Flecainide's development began in 1966 and was first synthesized in 1972 as an attempt to generate new anesthetics. 10 It is used to prevent supraventricular and ventricular arrhythmias, as well as paroxysmal atrial fibrillation and flutter. 12,1 Reserve class IC antiarrhythmics use for life-threatening ventricular arrhythmias only; Due to known proarrhythmic properties of flecainide and lack of evidence of improved survival for any antiarrhythmics, flecainide use should be restricted to patients with life-threatening ventricular arrhythmias; Ventricular proarrhythmic effects with AF/flutte Flecainide, encainide, and propafenone belong to class IC antiarrhythmic drugs. They are new and potent drugs which markedly depress Phase 0 of the action potential without affecting repolarization. Class IC drugs are very potent suppressors of premature ventricular complexes but their efficacy in t Flecainide. A class Ic antiarrhythmic agent used to manage atrial fibrillation and paroxysmal supraventricular tachycardias (PSVT). Encainide. A voltage-gated sodium channel blocker used for management of atrial or ventricular fibrillation, atrial flutter, and ventricular tachycardia, that is no longer used due to proarrhythmic adverse effects Flecainide is the prototypical class I agent and a very potent sodium channel blocker. Blocking the sodium channel can actually cause pacing thresholds to increase. So when you have a patient who is pacemaker dependent or already has a pacemaker, and you start that patient on flecainide, be aware that the pacing threshold can increase.

Propafenone and flecainide. Propafenone and flecainide are both class I antiarrhythmic drugs and share several characteristics. Indications, propafenone. Prophylaxis and treatment of life-threatening ventricular tachyarrhythmias. Propafenone is usually not the first-line therapy in this patient category Flecainide (Tambocor): Flecainide is a potent sodium channel blocker that may be used in atrial fibrillation patients without structural heart disease. 1,7 For atrial fibrillation maintenance, flecainide is generally dosed at 50 to 150 mg orally twice daily, with a dose decrease of 50% if the glomerular filtration rate is 50 mL/min or less; plasma levels are monitored closely. It also may be taken as a single oral loading dose of 200 to 300 mg for atrial fibrillation conversion For propafenone or flecainide, if needed, the single dose may be followed once by a half dose 8 hrs later. These doses all assume that the patient is not already on an AAD. If the patient is already taking an AAD, these pill-in-the-pocket regimens are not appropriate as there is no significant experience in such circumstances - with one exception Flecainide. Flecainide is a class IC antiarrhythmic drug that blocks conduction through sodium channels with little to no effect on the refractory properties of the tissue. From: Avery's Diseases of the Newborn (Eighth Edition), 2005. Related terms: Cardioversion; Digoxin; Propafenone; Antiarrhythmic Agent; Quinidine; Amiodarone; Procainamid Flecainide (Tambocor) is a class 1-C anti-arrhythmic drug that is used in the prevention of ventricular and supraventricular tachyarrhythmia in patients with a structurally normal heart. Flecainide Uses: Paroxysmal atrial fibrillation/flutter and paroxysmal supraventricular tachycardias (prevention)

Flecainide belongs to a class of drugs called antiarrhythmics. A class of drugs refers to medications that work similarly. They have a similar chemical structure and are often used to treat. Flecainide acetate is a new orally active antidysrhythmic agent classified in the Ic category. Flecainide is effective in suppressing 88 to 100 percent of abnormal cardiac rhythms in the form of complex ventricular dysrhythmias, including couplets, ventricular tachycardia, reentrant junctional tachycardia, and Wolff-Parkinson-White syndrome Flecainide has been assigned to pregnancy category C by the FDA. Animal studies have revealed teratogenicity and embryotoxicity in rabbits that were given doses 30 to 35 mg/kg/day. No data from controlled studies in human pregnancy are available

Class Ib drugs do not block potassium channels directly. Class Ib drugs are used for the suppression of ventricular arrhythmias (ventricular premature beats, ventricular tachycardia,. Flecainide is an IC antiarrhythmic drug approved in 1984 from the Food and Drug Administration for the suppression of sustained ventricular tachycardia and later for acute cardioversion of atrial fibrillation and for sinus rhythm maintenance Effects of flecainide (a class IC antiarrhythmic drug) on the maximum rate of rise (\(\dot V_{\max } \)) of action potentials (APs) were studied in guinea-pig papillary muscles, with special reference to their time, voltage, and action potential duration (APD) dependence in the presence and absence of nicorandil. Nicorandil was used to shorten APD, i.e., the time period of inactivation state of sodium channels

Its predominant electrophysiologic effect is to prolong the refractory period of atrial and ventricular myocardium and the AV junction. In addition, it has class I effects (sodium channel-blocking properties), some class II effects (β- and α-receptor blockade), and some class IV effects (calcium channel blockade) Quinidine, disopyramide, procainamide, lidocaine, mexiletine, flecainide, and propafenone are all class I antiarrhythmic drugs ( table 1) used for the treatment of various atrial and ventricular arrhythmias. This topic will review the major side effects of the various drugs. Recommendations for the clinical role of these drugs in the treatment of.

Class Ic antiarrhythmic agents flecainide and propafenone are amongst the drugs most frequently prescribed to control atrial arrhythmias, in particular atrial fibrillation (AF). Despite being cited in some guidelines as a warning when using 1c antiarrhythmic agents, atrial flutter (AFl) with 1:1 atr Propafenone is more selective for cells with a high rate, but also blocks normal cells more than class Ia or Ib anti-arrhythmic medications. Propafenone differs from the prototypical class Ic antiarrhythmic in that it has additional activity as a beta-adrenergic blocker which can cause bradycardia and bronchospasm Flecainide is a Class IC antiarrhythmic associated with a possible risk for QT prolongation and TdP; flecainide increases the QT interval, but largely due to prolongation of the QRS interval. Although causality for TdP has not been established for flecainide, patients receiving concurrent drugs which have the potential for QT prolongation may. Flecainide is used to prevent certain types of life-threatening irregular heartbeats. Flecainide is in a class of medications called antiarrhythmics. It works by slowing electrical signals in the heart to stabilize the heart rhythm

Treatment with Class I or III antiarrhythmics (e.g., amiodarone, flecainide, propafenone, quinidine, disopyramide, dofetilide, sotalol) or drugs that are strong inhibitors of CYP3A (e.g., ketoconazole) must be stopped before starting MULTA The chemistry, electrophysiology, pharmacokinetics, clinical use and efficacy, adverse effects, drug interactions, and dosage of encainide hydrochloride and flecainide acetate are reviewed. Encainide and flecainide are class 1c antiarrhythmic agents that slow myocardial conduction and mildly prolong the duration of repolarization Class Ia antiarrhythmic drugs (quinidine, procainamide, and disopyramide) have become less commonly prescribed than in the past because of their side effect profiles. The class Ic agents, namely flecainide and propafenone, have more favorable side effect profiles and are more commonly utilized The Class III drugs Amiodarone, Sotatol, Dofetilide, and Azimilide appear to be safer to use if you have structural heart disease. 41 In structurally normal hearts, Class IC drugs (Flecainide and Propafenone) cause less heart rhythm problems and are the least toxic. 4

Ten Pearls for the Use of Antiarrhythmic Drugs for Atrial

Sotalol has a beta blocker component to it but also works as a class III anti-arrhythmic medication. Flecainide can also cause arrhythmias, so this is why it is only given to patients that have a normal functioning heart. Sotalol. Sotalol is a mixture of a beta-blocker and an anti-arrhythmic. In low doses, it acts like a beta blocker Class IC antiarrhythmic drugs (sodium channel blockers) Class IC antiarrhythmic drugs are contraindicated in patients with myocardial scar, left ventricular hypertrophy, structural heart disease ,and coronary artery disease.
