THREE main mechanisms by which current drugs appear to produce their anticonvulsant activity:
1) Modulation of intrinsic membrane conductances, primarily voltage-gated cationic channels
2) Suppression of excitatory amino acid-mediated synaptic transmission
3) Enhancement of GABAergic inhibitory synaptic transmission, via post-synaptic receptor modulation, inhibition of GABA metabolism or blockade of GABA transport.
