Description: Eleclazine, also known as GS-6615, is a selective late sodium current inhibitor. Eleclazine is potentially useful for treatment of coronary vasodilators, antiarrhythmics and vasodilators. Eleclazin showed a shortening of the QTc interval (the time interval between the start of the Q-wave and end of the T-wave in the heart’s electrical cycle) in patients with long QT-3 (LQT3) syndrome. LQT3 is a genetic disorder that prolongs the heart’s QTc interval and can cause life-threatening cardiac arrhythmias (abnormal heartbeats).
