Ethacizine (hydrochloride)

Ethacizine hydrochloride (Ethacizin; NIK-244) is a longer-lasting Class Ic antiarrhythmic agent than Flecainide[1]. Ethacizine hydrochloride (Ethacizin; NIK-244) inhibits the depolarizing current responsible for the intraatrial and His-Purkinje-ventricular conduction[2].
