      A. Representative time course of PF-05241328 (#P-345) inhibition of NaV1.7 channel current. Membrane potential was held at -100 mV. Current was elicited by a 100 ms voltage step to 0 mV every 10 sec and inhibited by 10 µM and 50 µM PF-05241328 application (horizontal bars). B. Superimposed traces of NaV1.7 current upon application of control and of 10 µM and 50 µM PF-05241358, as indicated.
