Pain is caused by the stimulation of free nerve endings. When the nerve endings
are stimulated, sodium enters the neuron, causing depolarization of the nerve
and subsequent initiation of an action potential. The action potential is
propagated down the nerve toward the central nervous system, which interprets
this as pain. Benzocaine acts to inhibit the voltage-dependent sodium channels
(VDSCs) on the nerve membrane, stopping the propagation of the action
