Mexiletine hydrochloride

SKU: orb1309949

Description

Mexiletine hydrochloride is a Class IB antiarrhythmic agent that functions as a voltage-gated sodium channel blocker. It is widely used in cardiovascular research to study arrhythmia mechanisms, employing both in vitro electrophysiology and in vivo animal models to investigate its modulation of cardiac action potentials and Purkinje fiber automaticity.

Bioactivity

• In Vivo:
  Mexiletine shortened the cardiac Purkinje fiber effective response period (ERP) less than the action potential duration (APD), resulting in higher ERP/APD ratios.Mexiletine had no significant effect on atrioventricular conduction velocity, resting membrane potential, sinus node autoregulation, systolic arterial pressure, left ventricular function, or QRS or QT intervals. Mexiletine inhibits the inward flow of sodium ions through inhibition of sodium channels (requiring pulse initiation and conduction), which in turn reduces the rate of action potential elevation.
• In Vitro:
  Mexiletine shortened the cardiac Purkinje fiber effective response period (ERP) less than the action potential duration (APD), resulting in higher ERP/APD ratios.Mexiletine had no significant effect on atrioventricular conduction velocity, resting membrane potential, sinus node autoregulation, systolic arterial pressure, left ventricular function, or QRS or QT intervals.
