The apparent permeabilities ( Papp ) of gemifloxacin across the Caco - 2 cell monolayer were 1 . 20 +/- 0 . 09 x 10 ( - 5 ) cm / s for apical to basal ( absorptive ) transport , and 2 . 13 +/- 0 . 6 x 10 ( - 5 ) cm / s for basal to apical ( secretory ) transport for a 5 - 500 mu M concentration range , suggesting the involvement of a carrier - mediated efflux in the secretory transport .
