Antiepileptics, also known as anticonvulsants, are medications primarily used to treat epilepsy, as well as generalized or partial seizures. On rare occasions, these medications can be used to treat mood disorders.

valproic acid concentration can be mis-leading, because it can be normal or even low despite high concentrations of free valproic acid (11). If dosages are adjusted on the basis of total valproic acid levels, patients who are hypoalbuminemic can be overdosed, leading to clinically signifi-cant neurologic symptoms or toxicity (10, 15). 37.

Treatment with the histone deacetylase inhibitor valproic acid (VPA) during reprogramming can improve the induction of iPSCs. To examine the specific mechanism underlying the role of VPA in reprogramming, we transfected human bone marrow-derived cells (HSC-J2 and HSC-L1) with lentiviruses carrying defined factors (OCT4, SOX2, KLF4, and c-MYC ...

Valproate was significantly more effective in groups with levels >71 mcg/mL, compared with placebo. Groups with serum valproate of 94 to 107 mcg/mL and >107 mcg/mL also showed greater response than did the group with ≤55 mcg/mL. Effect sizes for the 94 to 107 and >107 mcg/mL groups were –1.06 and –1.07 respectively, similar to 12-point ...

Environmental factors, such as medication during pregnancy, are one of the major causes of autism spectrum disorder (ASD). Valproic acid (VPA) intake during pregnancy has been reported to dramatically elevate autism risk in offspring. Recently, researchers have proposed that VPA exposure could induce excitatory or inhibitory synaptic dysfunction. However, it remains to be determined whether ...Valproic acid (VPA) is widely recognized for its use in the control of epilepsy and other neurological disorders in the past 50 years.

The mechanism of action of valproic acid is complex, calling for a decrease in neuronal hyperexcitability both by strengthening GABAergic transmission and by inhibiting sodium and especially calcium ion channels. Valproic acid activates or inhibits the various targets by direct routes or by unknown mechanisms. Cellular targetsAbstract. Salicylic acid displaces valproic acid from plasma protein binding sites (primarily albumin) and can inhibit valproic acid metabolism, via the β-oxidation pathway, by 66 %. Concurrent administration of an antipyretic dose of aspirin to children can result in a 23 % increase in free nonprotein-bound plasma valproic acid levels.Determination of valproic acid in the drug was carried out on the aluminum silica gel 60F 254 plates and using acetone-water-chloroform-ethanol-ammonia at a volume ratio of 30:1:8:5:11 as the mobile phase, respectively.
