Mechanism of action of class 2 antiarrhythmic drugs

Please note: The antiarrhythmic class based on mechanism of action represents only the main effect of the drug. Many antiarrhythmic drugs have additional

Amiodarone hydrochloride Mechanism of Action. It’s primarily a class III antiarrhythmic. Like other antiarrhythmic drugs of this class, amiodarone works primarily by blocking potassium rectifier currents that are responsible for the repolarization of the heart during phase 3 of the cardiac action potential. Digoxin Mechanism of Action

Amiodarone mechanism of action, Amiodarone is primarily a class III antiarrhythmic. Like other antiarrhythmic agents of this class, amiodarone

The resulting class II antiarrhythmic drug, pro- pranolol Emerging class III antiarrhythmic agents: mechanism of action and proarrhythmic potential.

Disopyramide is an antiarrhythmic drug that belongs to class Ia. As with other class I antiarrhythmic drugs, such as quinidine, ajmaline, and procainamide, the mechanism of action of disopyramide is to lengthen the action potential duration (APD) of cardiomyocytes, reflected by the rightward shift of the action potential curve.
