Dronedarone (hydrochloride)

Dronedarone is an antiarrhythmic agent and a derivative of amiodarone (Cay-15213). It inhibits muscarinic acetylcholine receptor-dependent potassium currents induced by carbachol (carbamoylcholine, Cay-14486) or intracellular loading of GTPgammaS in single cells isolated from guinea pig atria (IC50s = 0.1 and 1 µM, respectively). Dronedarone (50 and 100 mg/kg) reduces sinus frequency and prolongs action potential duration (APD) in isolated rabbit ventricular myocardium. It increases atrial APD and the atrial effective refractory period (AERP) in a dog model of atrial fibrillation induced by rapid right atrial pacing. Formulations containing dronedarone have been used in the treatment of atrial fibrillation.Formal Name: N-[2-butyl-3-[4-[3-(dibutylamino)propoxy]benzoyl]-5-benzofuranyl]-methanesulfonamide, monohydrochloride.
