Notes: Azimilide is a class III antiarrhythmic agent.{46367} It blocks rapidly activating delayed rectifier (IKr) and slowly activating delayed rectifier (IKs) potassium currents in isolated guinea pig ventricular myocytes (IC50s = 0.3 and 3 μM, respectively). Azimilide (0.1-10 μM) prolongs action potential duration (APD) in isolated calf Purkinje fibers and ventricular trabeculae in a concentration-dependent manner. It increases the effective refractory period (ERP) in isolated perfused guinea pig hearts and ferret papillary muscles. Azimilide (0.3-30 mg/kg) increases ERP and the absolute refractory period and decreases heart rate in dogs. It reduces mean arrhythmia score in a rat model of coronary artery ligation and reperfusion-induced severe ventricular arrhythmia. Azimilide (10-30 mg/kg) also prevents sustained and non-sustained ventricular tachyarrhythmias in dogs.
