NCIt definition : The hydrochloride salt of Dyclonine, an unclassified compound with local anesthetic
effect. Dyclonine reversibly binds to activated sodium channels on the neuronal membrane,
thereby decreasing the neuronal membrane's permeability to sodium ions, leading to
an increased threshold for excitation. This reversibly stabilizes the membrane and
inhibits depolarization, leading to the failure of a propagated action potential and
subsequent conduction blockade. This results in a transient and reversible loss of
sensation in a localized area of the body.;
