Fig. 3From: Impact of rifampicin-inhibitable transport on the liver distribution and tissue kinetics of erlotinib assessed with PET imaging in ratsMetabolism and plasma kinetics of 11C-erlotinib in the absence (control) and the presence of rifampicin (40 mg/kg i.v.). Data were obtained using arterial blood sampling (femoral artery) in additional rats (1 animal for each condition). In a, the percentage of parent (unmetabolized) 11C-erlotinib versus time is displayed. Corresponding plasma kinetics of parent 11C-erlotinib (metabolite-corrected arterial input function) are shown in bBack to article page
