Biochem/physiol Actions

Tocainide hydrochloride is a sodium channel blocker; Class IB antiarrhythmic.

Features and Benefits

Tocainide is voltage-dependent and use-dependent sodium channel blocker (class IB type antiarrhythmic); Ki = 115 μM in blockade of inactivated-state sodium channels; IC50 = 985μM in blockade of Na+ currents at a holding potential (HP) of -140 mV; IC50 = 254 μM in blockade of Na+ currents at HP -70 mV; IC50 = 523 μM in blockade of Na+ currents at tonic block (-100 mV); IC50 = 248 μM for use-dependent block at 10 Hz.
