This has something to do with gaba receptors. Let me see if I can explain it.
Inhibitor of gaba uptake - tiagabine
Blocks sodium channels and enhances the effect of gaba - topiramate
Inhibits gaba-transaminase and increases gaba concentration - vigabatrin
Increases brain gaba concentration - gabapentin
The answer is B - valproic acid. It decreases propagation of abnormal action potentials by enhancing inhibitory action of gaba in cns. Valproic acid is effective for absence, myoclonic, and generalized tonic-clonic seizures. Also, valproic acid is used to prevent mania in bipolar disorder, in mixed manic-depressive disorder, and management of acute mania. Other mood stabilizers and anticonvulsant is carbamazepine. I was not aware of lamictal.
In addition, doc for myoclonic seizure is valproic acid, but ethosuximide is preferred in absence seizure.

I am excited to post daily questions, and thanks for the :happy:stimulation:happy: you folks have generated
