چکیده انگلیسی
We sought to determine whether celecoxib would induce convulsions when coadministered with new quinolone antimicrobial agents in mice. The oral administration of celecoxib (500 mg/kg) alone or in combination with enoxacin (500 mg/kg), lomefloxacin (1000 mg/kg), ciprofloxacin (1000 mg/kg), or levofloxacin (1000 mg/kg) induced no convulsions in mice. In contrast, some nonsteroidal anti-inflammatory drugs (NSAIDs), fenbufen (200 mg/kg), indomethacin (500 mg/kg), and naproxen (500 mg/kg) induced convulsions in combination with the majority of the new quinolones tested. γ-Aminobutyric acid (GABA)A receptor blockade-mediated neuronal excitation is assumed to be involved in these toxic convulsions. Enoxacin (100 μM) and lomefloxacin (100 μM) only slightly reduced [3H]muscimol binding to GABAA receptors in mouse whole brain membrane. However, these reductions were markedly enhanced by the addition of fenbufen (100 μM), indomethacin (100 μM), or naproxen (100 μM). Conversely, celecoxib (100 μM) had no apparent effect on [3H]muscimol binding when applied alone or in combination with enoxacin or lomefloxacin. These results suggest that celecoxib may be a more desirable anti-inflammatory agent with respect to drug interactions with new quinolones compared with some conventional NSAIDs.
