Prevention of neurotransmitter-induced hyperexcitability of nerve cells via Kv7.2 channel and AKAP5 may also contribute to its mechanism. [55] Valproate has been shown to protect against a seizure-induced reduction in phosphatidylinositol (3,4,5)-trisphosphate (PIP3) as a potential therapeutic mechanism. [56] Valproate is a histone deacetylase ...
Derivatives: sodium valproate, valproate semisodium, divalproex sodium, valproate pivoxil; Valpromide (2-propylpentanamide) – anticonvulsant; same mechanism of action as valproic acid, plus inhibitor of epoxide hydrolase
The mechanism by which ethosuximide affects neuronal excitability includes block of T-type calcium channels, and may include effects of the drug on other classes of ion channel. The primary finding that ethosuximide is a T-type calcium channel blocker gained widespread support, but initial attempts to replicate the finding were inconsistent.
Reversible modification of the terminal tails of core histones constitutes the major epigenetic mechanism for remodeling higher-order chromatin structure and controlling gene expression. HDAC inhibitors (HDI) block this action and can result in hyperacetylation of histones, thereby affecting gene expression.
This is probably a side effect or even the actual mechanism of action for some antiepileptic drugs, since GABA can itself, directly or indirectly, act proconvulsively. [12] Another potential target of antiepileptic drugs is the peroxisome proliferator-activated receptor alpha .
Seppala also sent a team to study other clinics around the country. His staff went to facilities in Oregon and Missouri that were offering a mix of medically assisted treatments and 12-step. The team came back optimistic. “They saw in action how this could actually work,” Seppala said.

In pharmacology, a GABA transaminase inhibitor is an enzyme inhibitor that acts upon GABA transaminase. [1] Inhibition of GABA transaminase enzymes reduces the degradation of GABA, leading to increased neuronal GABA concentrations.
