> is GABITRIL any thing like gabapentin
In short no. Gabitril helps prevent GABA from being scavenged (blocks reuptake). Levels of GABA then build up and since it is an inhibitory neurotransmitter, this can help "stabilize" neuronal firing and help control seizures.
Gabapentin's molecule "looks like" the inhibitory neurotransmitter GABA, but its mechanism doesn't appear to be "GABA-ergic". Evidently, there are specific sites in the hippocampus where it acts as a selective calcium-ion channel blocker which also "stabilizes" neuronal firing but in a more selective region of the brain.
