The effect of probenecid (PRO) on norfloxacin (NOR) blood-brain barrier transport was investigated with rats by microdialysis. Maximum brain drug concentrations were rapidly attained, and the brain penetration factor was close to 5% in the absence and presence of PRO. In conclusion, PRO has no effect on NOR blood-brain barrier transport.
Multiple drug transporters contribute to the brain transfer of levofloxacin.
