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]. | [in vivo]
NIK-244 (1-300 ug) injects directly into the SA node and PM preparations shows negative chronotropic, negative inotropic and coronary vasodilator[1]. | [References]
