Chemical Properties White-to-Off-White Crystalline Powder Usage Used as an anticonvulsant Usage anticonvulsant, antimigraine, GABA-A agonist, AMP/kinate glutamate receptor antagonist, carbonic anhydrase inhibitor Biological Activity Anticonvulsant.

Antagonizes GluR5 kainate receptors (IC 50 = 0.46 μ M), acts as a positive allosteric modulator of GABA A receptor-mediated currents, inhibits Na v channels (IC 50 = 48.9 μ M) and inhibits L-type Ca 2+ channels.

Also inhibits carbonic anhydrase (CA) (K i values are 0.1 and 0.2 μ M at rat CA II and CA IV respectively), which lowers intracellular neuronal pH.
