The scientific and medical history of valproic acid is relatively long, compared with other frequently used psychopharmacologic agents. Valproic acid was used as an organic solvent in research laboratories for eight decades, until the fortuitous observation of action against pentylenetetrazol-induced convulsions in rodents.The recommended dose of valproic acid is based on body weight. The dose of medication is usually started at a low level (15 mg per kg of body weight per day) to minimize side effects, and increased gradually until seizures are controlled with a minimum of side effects. The maximum recommended dose is 60 mg per kg of body weight per day.

Abstract. Valproic acid (VPA), a well-established therapy for seizures and bipolar disorder, has recently been shown to inhibit histone deacetylases (HDACs). Similar to more widely studied HDAC inhibitors, VPA can cause growth arrest and induce differentiation of transformed cells in culture. Whether this effect of VPA is through inhibition of HDACs or modulation of another target of VPA has ...Valproic acid (VPA) is a widely used antiepileptic drug (AED). It is effective against many types of seizure disorders either alone or as a component of a multidrug regimen. It was commercialized in 1969 in France and 1978 in United States. VPA has a broad spectrum of activity against generalized and partial epilepsy in both adults and children.

Valproic acid (VPA) is a branched short-chain fatty acid clinically used as a broad-spectrum antiepileptic drug in the treatment of neurological disorders, which has shown promising antiviral activity against some herpesviruses. Moreover, its amidic derivatives valpromide and valnoctamide also share this antiherpetic activity.VALPROIC ACID (val PROE ik AS id) prevents and controls seizures in people with epilepsy.

Although acute VPA intoxication frequently results in mild, self ...Figure 1. Chart depicting the individual subject's serum valproic acid levels at 12 and 24 h. It is observed that measuring serum VPA levels at 24 h is recommended and provides a more accurate value for patients on OD dosage. Measuring it at 12 h in case of OD dosing would give a 1.3 times higher value than the actual trough value.Valproic acid and derivative products are contraindicated in patients with known urea cycle disorders (UCD), as hyperammonemic encephalopathy, sometimes fatal, has been reported on these patients following the initiation of treatment. Prior to the initiation of therapy, the evaluation for UCD should be considered in patients with history of ...

Valproic acid and felbamate are associated with hepatotoxicity and, therefore, contraindicated in patients with hepatic failure. The liver metabolizes many others, and dosage adjustments need to be made before initiation. Similarly, those with renal impairments need to adjust dosing when AEDs are primarily excreted via the kidneys.Introduction. VPA (valproic acid), a clear, colorless, eight-carbon branched-chain fatty acid, was first produced in 1882 as an organic solvent ().Then, in 1963, the therapeutic potential of VPA was fortuitously discovered by Carraz et al.
