Clonazepam’s exact mechanisms not understood; benzodiazepines potentiate the effects of GABA, an inhibitory neurotransmitter.

Mechanism of action not understood: antiepileptic activity may be related to the metabolism of the inhibitory neurotransmitter, GABA; divalproex sodium is a compound containing equal proportions of valproic acid and sodium valproate.

Drug Study of Gabapentin: Mechanism of action not understood; antiepileptic activity may be related to its ability to inhibit polysynaptic responses and block posttetanic potentiation.

Exact mechanisms of action not understood; acts mainly at the limbic system and reticular formation; may act in spinal cord and at supraspinal sites to produce skeletal muscle relaxation; potentiates the effects of GABA, an inhibitory neurotransmitter; anxiolytic effects occur at doses well below those necessary to cause sedation, ataxia; has little effect on cortical function.
