Here we show that prolonged sensory-selective nerve block can be produced by specific concentrations of surfactants-such as are used to enhance drug flux across skin-in combination with QX-314, a lidocaine derivative that has relative difficulty penetrating nerves. For example, injection of 25 mM QX-314 ...[more]
