Dronedarone

• Description:

  Dronedarone (SR 33589), a derivative of amiodarone (HY-14187), is a class III antiarrhythmic agent for the study of atrial fibrillation (AF) and atrial flutter. Dronedarone is a potent blocker of multiple ion currents, including potassium current, sodium current, and L-type calcium current, and exhibits antiadrenergic effects by noncompetitive binding to β-adrenergic receptors. Dronedarone is a substrate for and a moderate inhibitor of CYP3A4[1].
