Recent research has demonstrated that the receptor for glutamate, a major excitatory neurotransmitter, may play an important role in the expression of benzodiazepine withdrawal signs. This proposal is based on various observations. For example, antagonists for <I>N</I>-methyl-D-aspartate (NMDA), non-NMDA and metabotropic glutamate (mGlu) receptors can suppress the behavioral signs of benzodiazepine withdrawal in mice and rats. Furthermore, the NMDA receptor in the cerebrocortical area of diazepam-withdrawn rats is upregulated. Finally, the stimulation of phosphoinositide hydrolysis mediated by mGluR is enhanced in cerebrocortical slices from lorazepam-withdrawn mice. These findings show that the upregulation of signal transduction mediated by glutamate receptors during diazepam withdrawal plays a role in the neuroadaptive response responsible for the expression of diazepam withdrawal signs. Furthermore, ligands for glutamate receptors may be suitable targets for treating benzodiazepine withdrawal signs.
