In vitro, gabapentin modulates the action of the GABA synthetic enzyme, glutamic acid decarboxylase (GAD) and the glutamate synthesizing enzyme, branched-chain amino acid transaminase. Results with human and rat brain NMR spectroscopy indicate that gabapentin increases GABA synthesis.
Another synergistic action of GABA is manifested by the activation of GABA (B) receptors localized on postsynaptic sites. Binding of GABA to these receptors leads to the activation of G-protein activated Inward Rectifier K + (GIRK or K ir 3) channel 6, hyperpolarization and postsynaptic inhibition 1.n the postsynaptic membrane, GABA (B) receptors activate K + channels and induce slow inhibitory postsynaptic potentials that inhibit GABA (A) receptor activity. Receptors on extrasynaptic membranes are probably activated by a GABA overflow from nearby synapses.Adapted from reference 5 with permission of Elsevier.
