Valproic acid (dipropylacetic acid), approved by the FDA in 1978, is a simple branched-chain carboxylic acid with a broad-spectrum mechanism of action and antiseizure profile. Mechanism of action Similar to phenytoin and carbamazepine, valproic acid reduces sustained high-frequency neuronal firing at therapeutic doses by stabilizing the inactive state of voltage-gated Na + channels .
After more than a century from its discovery, valproic acid (VPA) still represents one of the most efficient antiepileptic drugs (AEDs). Pre and post-synaptic effects of VPA depend on a very broad spectrum of actions, including the regulation of ionic currents and the facilitation of GABAergic over glutamatergic transmission.
