Reaction: ABCG2 transports Cipro from intestinal cell to extracellular space

- in pathway: Ciprofloxacin ADME
Inhibition studies with Caco-2 cells show there may be a number of transport proteins involved in the transport of ciprofloxacin (Cipro) through GI cells (Cavet et al, 1997). Secretion of Cipro into the GI lumen involves two distinct transport steps: at the basolateral cell membrane, Cipro is accumulated within the cytosol, with secretion then occurring across the apical membrane (Lowes & Simmons, 2002; Xia et al, 2005; Haslam et al, 2011; reviewed by Alvarez et al, 2008). The importance of this process relative to the main excretion pathways (renal and biliary) is unclear, however.
