Ethacizine (ethacyzine) is a class Ic antiarrhythmic agent, related to moracizine. It is used in Russia and some other Commonwealth of Independent States countries for the treatment of severe and/or refractory ventricular and supraventricular arrhythmias, especially those accompanied by organic heart disease. It is also indicated as a treatment of refractory tachycardia associated with Wolff–Parkinson–White syndrome.

Sample Use Guides
The initial dose is 50 mg (1 table) 2-3 times a day. In case of insufficient clinical effect, the dose is increased (under compulsory ECG monitoring) to 50 mg 4 times a day (200 mg) or 100 mg 3 times daily (300 mg).
Route of Administration:
Oral
Ethacizine applied in the concentration range between 1 X 10(-7) and 1 X 10(-5) g/ml decreased the rate of action potential growth (Vmax) of the mammal myocardium. Inhibition of the Vmax was accompanied by the diminution of the force of contraction which involved two phases. Ethacizine also decreased the overshoot of slow response action potential with the time constant similar to that in the first rapid phase of force reduction.
