Class IC drugs: propafenone and flecainide

Cardiovascular Drugs and Therapy
P Puech, J P Gagnol

Abstract

Recently published clinical data on the efficacy and side-effect profiles of flecainide and propafenone are reviewed. Both compounds appear to be clinically effective for the control of a variety of cardiac arrhythmias, both ventricular as well as supraventricular. These include termination of atrial fibrillation, control of junctional tachycardias, and control of ventricular arrhythmias. While the incidence of noncardiac side effects appeared to be similar for both compounds, proarrhythmic effects appeared to be higher on flecainide than on propafenone, especially with doses higher than 400 mg.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.
