Description

Valproic acid, supplied as the sodium salt valproate semisodium or divalproex sodium, is a fatty acid with anticonvulsant properties used in the treatment of epilepsy. The mechanisms of its therapeutic actions are not well understood. It may act by increasing gamma-aminobutyric acid levels in the brain or by altering the properties of voltage dependent sodium channels. Typically supplied in the sodium salt form (CAS number: 76584-70-8). Valproic Acid is also a histone deacetylase inhibitor and is under investigation for treatment of HIV and various cancers.

Pharmacology
IndicationFor treatment and management of seizure disorders, mania, and prophylactic treatment of migraine headache. In epileptics, valproic acid is used to control absence seizures, tonic-clonic seizures (grand mal), complex partial seizures, and the seizures associated with Lennox-Gastaut syndrome.
PharmacodynamicsThe relationship between plasma concentration and clinical response is not well documented. One contributing factor is the nonlinear, concentration dependent protein binding of valproate which affects the clearance of the drug. Thus, monitoring of total serum valproate cannot provide a reliable index of the bioactive valproate species. For patients with epilepsy, the therapeutic range is commonly considered to be 50 to 100 mcg/mL of total valproate. However, patients may be controlled at lower or higher doses.
Mechanism of actionValproic Acid dissociates to the valproate ion in the gastrointestinal tract and then binds to and inhibits GABA transaminase. The drug's anticonvulsant activity may be related to increased brain concentrations of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the CNS, by inhibiting enzymes that catabolize GABA or block the reuptake of GABA into glia and nerve endings. Valproic Acid may also work by suppressing repetitive neuronal firing through inhibition of voltage-sensitive sodium channels. It is also a histone deacetylase inhibitor. Valproic acid has also been shown to be an inhibitor of an enzyme called histone deacetylase 1 (HDAC1). HDAC1 is needed for HIV to remain in infected cells. A study published in August 2005 revealed that patients treated with valproic acid in addition to highly active antiretroviral therapy (HAART) showed a 75% reduction in latent HIV infection.
AbsorptionRapid absorption from gastrointestinal tract. Although the rate of valproate ion absorption may vary with the formulation administered (liquid, solid, or sprinkle), conditions of use (e.g., fasting or postprandial) and the method of administration (e.g., whether the contents of the capsule are sprinkled on food or the capsule is taken intact), these differences should be of minor clinical importance under the steady state conditions achieved in chronic use in the treatment of epilepsy. Food has a greater influence on the rate of absorption of the Depakote tablet (increases Tmax from 4 to 8 hours) than on the absorption of Depakote sprinkle capsules (increase Tmax from 3.3 to 4.8 hours). Furthermore, studies suggest that total daily systemic bioavailability (extent of absorption) is the primary determinant of seizure control.
Volume of distribution
  • 11 L/1.73 m2 [total valproate]
  • 92 L/1.73 m2 [free valproate]
Protein bindingConcentration-dependent, from 90% at 40 µg/mL to 81.5% at 130 µg/mL. Higher than expected free fractions occur in the elderly, in hyperlipidemic patients, and in patients with hepatic and renal diseases. It may also affect the extent of protein binding of other drugs such as phenytoin or carbamazepine.
Metabolism

Valproic Acid is metabolized almost entirely by the liver. In adult patients on monotherapy, 30-50% of an administered dose appears in urine as a glucuronide conjugate. Mitochondrial ß-oxidation is the other major metabolic pathway, typically accounting for over 40% of the dose. Usually, less than 15-20% of the dose is eliminated by other oxidative mechanisms. Less than 3% of an administered dose is excreted unchanged in urine.

Half life9-16 hours (following oral administration of 250 mg to 1000 mg)
Clearance
  • 0.56 L/hr/1.73 m2 [plasma clearance, total valproate]
  • 4.6 L/hr/1.73 m2 [plasma clearance, free valproate]
  • 4.8 ± 0.17 L/hr/1.73 m2 [males, unbound clearance]
  • 4.7 ± 0.07 L/hr/1.73 m2 [females, unbound clearance]
ToxicityOral, mouse: LD50 = 1098 mg/kg; Oral, rat: LD50 = 670 mg/kg. Symptoms of overdose may include coma, extreme drowsiness, and heart problems. The safety and tolerability of valproate in pediatric patients were shown to be comparable to those in adults.
