| Abstract: | The ability of MK-801, an N-methyl-D-aspartate (NMDA)-channel antagonist, to suppress alcohol withdrawal seizures generated audio-genically was studied in adult male rats using a cross-over experimental design. MK-801 treatment reduced overall seizure score and proportion of rats seizing. In comparison to other seizure models, alcohol withdrawal seizures seem to be particularly sensitive to MK-801, suggesting that mechanisms which result in seizure susceptibility after withdrawal of chronic ethanol exposure may be dependent upon sensitization or upregulation of NMDA processes. |
