Notes: Mexiletine is a voltage-gated sodium channel blocker and class Ib antiarrhythmic agent that preferentially binds to open/inactive channels.{40451} It inhibits aconitine-induced dysrhythmias in mice with ED50 values of 57 and 107 mg/kg for intraperitoneal and oral administration, respectively.{40452} Mexiletine decreases or inhibits conduction across the Purkinje fiber-muscle junction, shortens action potential duration, and decreases the refractory period when used at concentrations less than 5 µg/ml in isolated canine Purkinje fiber and ventricular muscle preparations.{40453}
