Norfloxacin-induced electroencephalogram alteration and seizures in rats are not triggered by enhanced levels of intracerebral glutamate

Antimicrob Agents Chemother. 2003 Nov;47(11):3660-2. doi: 10.1128/AAC.47.11.3660-3662.2003.

Abstract

Pharmacokinetic-pharmacodynamic modeling of the electroencephalogram (EEG) effect was combined with intracerebral glutamate determinations using microdialysis for rats receiving norfloxacin intravenously (150 mg/kg of body weight). The EEG effect (accompanied by tremors and seizures) was consistently observed without glutamate level modifications. Therefore, norfloxacin-inducted seizures are not triggered by intracerebral glutamate level enhancement.
