MECHANISM OF ACTION
The precise mechanism by which tiagabine exerts its antiseizure effect
is unknown,
although it is believed to be related to its ability, documented in
_in vitro_ experiments, to
enhance the activity of gamma aminobutyric acid (GABA), the major
inhibitory
neurotransmitter in the central nervous system. These experiments have
shown that
tiagabine binds to recognition sites associated with the GABA uptake
carrier. It is
thought that, by this action, tiagabine blocks GABA uptake into
presynaptic neurons,
permitting more GABA to be available for receptor binding on the
surfaces of post-
synaptic cells. Inhibition of GABA uptake has been shown for
synaptosomes, neuronal
cell cultures, and glial
