Description
Valproic acid and its salt Magnesium Valproate is major antiepileptic drugs for the treatment of absence, myoclonic, and generalized tonic – clonic seizures and also may be effective against complex partial seizures. The most cited mechanisms are the increase in GABA function and the blockade of voltage-dependent Na+-channels. The most common side effects are gastrointestinal disturbances and sedation. The most serious adverse effect is liver damage, although this is rare. Teratogenic effects, predominantly spina bifida, are reported frequently.
