However , the number of studies that have focused on species differences in nonlinear PK is very limited ; thus , the aim of this study was to clarify the mechanism of the nonlinear PK of E2074 ( 2 - [ ( 2R ) - 2 - fluoro - 3 - { ( 3r ) - [ ( 3 - fluorobenzyl ) oxy ] - 8 - azabicyclo [ 3 . 2 . 1 ] oct - 8 - yl } propyl ] - 4 , 5 - dimethyl - 2 , 4 - dihydro - 3H - 1 , 2 , 4 - triazol - 3 - one ) , a novel sodium channel inhibitor , in rats , dogs , and monkeys .
