Dronedarone is a class III antiarrhythmic agent primarily targeting ion channels to manage atrial fibrillation (AF) and atrial flutter. It effectively inhibits multiple ion currents, including potassium, sodium, and L-type calcium currents, while also displaying antiadrenergic properties through noncompetitive binding to β-adrenergic receptors. Additionally, Dronedarone acts as a moderate inhibitor and substrate for CYP3A4, making it valuable for pharmacological studies in cardiac rhythm disorders.
