Mechanism of Action

Gabapentin is structurally related to the neurotransmitter GABA but is neither a GABA agonist nor antagonist. High affinity gabapentin binding sites are located throughout the brain. These sites correspond to the presence of voltage-gated Ca channels particularly controlling the ?-2/?-1 subunit. This channel appears to be located presynaptically and may modulate the release of excitatory neurotransmitters which participate in epileptogenesis and nociception.
