Biochem/physiol Actions

Tocainide hydrochloride is a primary amine analog of lidocaine (lignocaine), used for the treatment of tinnitus. It blocks the sodium channels in the pain-producing foci in the nerve membranes and renders an analgesic effect in trigeminal neuralgia.

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