“Conclusions These data demonstrate that gabapentin effectively inhibits acetic acid –induced nociception, and the antinociceptive effect of gabapentin correlates with the suppression of noxious-evoked release of excitatory amino acids in the spinal cord.”
“When compared to saline-treated rats, animals pretreated with 100 mg/kg gabapentin showed suppression of the acetic acid –induced increases in glutamate, aspartate, and serine concentrations.”
