Description	Pilsicainide (SUN 1165 free acid) is a potent sodium channel blocker and potent class Ic antiarrhythmic agent[1][2].
Related Catalog	Signaling Pathways >> Membrane Transporter/Ion Channel >> Sodium Channel Research Areas >> Cardiovascular Disease
In Vitro	Pilsicainide (SUN 1165 free acid; 10-200 μg/mL) decreases peak amplitude of the net inward current in a dose-dependent manner with an IC50 of 29.2 μg/mL in levo-thyroxine (T4)-treated rat atrial cells[1].
In Vivo	Pilsicainide (SUN 1165 free acid; 2 mg/kg; i.v.; once) decreases the conduction velocity in T4-treated rat atrium by decreasing the Max dV/dt and net inward current[1]. Animal Model: Male Sprague-Dawley (SD) rats weighing from 200 to 220 g, with levo-thyroxine (T4) treatment[1] Dosage: 2 mg/kg Administration: Bolus injection into right external carotid vein within 2 minutes, once Result: Elongated the QT interval at 15 and 60 minutes after administration. Shortened P wave and QRS complex durations. Markedly decreased action potential amplitudes (APA) and Max dV/dt, and significantly lengthened the action potential durations.
