Valproate (VPA), also known valproic acid, sodium valproate, and divalproex sodium, is a medication primarily used to treat epilepsy and bipolar disorder and to prevent migraine headaches.[2] It is useful for the prevention of seizures in those with absence seizures, partial seizures, and generalized seizures. It can be given intravenously or by mouth. Long acting formulations exist.[2]
Common side effects include nausea, vomiting, sleepiness, and a dry mouth. Serious side effects can include liver problems and regular monitoring of liver function tests is therefore recommended. Other serious risks include pancreatitis and an increased suicide risk. It is known to cause serious abnormalities in the baby if taken during pregnancy. Because of this it is not typically recommended in women of childbearing age who have migraines. It is unclear how valproate works.[2]
Valproate was first made in 1881 and come into medical use in 1962.[3] It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.[4] It is available as a generic medication.[2] The wholesale cost is between 0.14 and 0.52 USD per day.[5] In the United States it costs about 0.90 USD per day. It is marketed under the brand name Depakote among others.[2]

Medical uses
Its primary use to treatment epilepsy and bipolar disorder. It is also used to prevent migraine headaches.[6]
Epilepsy
Valproate has a broad spectrum of anticonvulsant activity, although it is primarily used as a first-line treatment for tonic-clonic seizures, absence seizures and myoclonic seizures and as a second-line treatment for partial seizures and infantile spasms.[6][7] It has also been successfully given intravenously to treat status epilepticus.[8][9][10]
Psychiatric disorders
Valproate products are also used to treat manic or mixed episodes of bipolar disorder.[11]
Off-label uses include impulse control disorders, suggested by recent evidence of efficacy in controlling this adverse effect of Parkinson's disease medical therapy.[12]
Migraines
Valproate is also used to prevent migraine headaches. Because this medication can be potentially harmful to the fetus, valproate should be considered for women of childbearing potential only after the risk have been discussed.[13]
Other
The medication has been tested in the treatment of AIDS and cancer, owing to its histone deacetylase-inhibiting effects.[14]
Adverse effects
See also: List of adverse effects of valproic acid and List of adverse effects of valproate semisodium
Most common adverse effects include:[13]
- Nausea (22%)
- Drowsiness (19%)
- Dizziness (12%)
- Vomiting (12%)
- Weakness (10%)
Serious adverse effects include:[13]
- Bleeding
- Low blood platelets
- Encephalopathy
- Suicidal behavior and thoughts
- Low body temperature
Valproic acid has a black box warning for hepatotoxicity, pancreatitis, and fetal abnormalities.[13]
Other possible side effects
There is evidence that valproic acid may cause premature growth plate ossification in children and adolescents, resulting in decreased height.[15][16][17][18] Valproic acid can also cause mydriasis, a dilation of the pupils.[19] There is evidence that shows valproic acid may increase the chance of polycystic ovary syndrome (PCOS) in women with epilepsy or bipolar disorder. However, studies have shown this risk of PCOS is higher in women with epilepsy compared to those with bipolar disorder.[20]
Pregnancy
Valproate causes birth defects; exposure during pregnancy is associated with about three times as many major abnormalities as usual, mainly spina bifida with the risks being related to the strength of medication used and use of more than one drug.[21][22] More rarely, with several other defects, possibly including a "valproate syndrome".[23] Characteristics of this valproate syndrome include facial features that tend to evolve with age, including a triangle-shaped forehead, tall forehead with bifrontal narrowing, epicanthic folds, medial deficiency of eyebrows, flat nasal bridge, broad nasal root, anteverted nares, shallow philtrum, long upper lip and thin vermillion borders, thick lower lip and small downturned mouth.[24] While developmental delay is usually associated with altered physical characteristics (dysmorphic features), this is not always the case.[25]
Children of mothers taking valproate during pregnancy are at risk for lower IQs.[26][27][28] Maternal valproate use during pregnancy has been associated with a significantly higher probability of autism in the offspring.[29] A 2005 study found rates of autism among children exposed to sodium valproate before birth in the cohort studied were 8.9%.[30] The normal incidence for autism in the general population is estimated at less than one percent.[31] A 2009 study found that the 3-year-old children of pregnant women taking valproate had an IQ nine points lower than that of a well-matched control group. However, further research in older children and adults is needed.[32][33][34]
Sodium valproate has been associated with the rare condition paroxysmal tonic upgaze of childhood, also known as Ouvrier–Billson syndrome, from childhood or fetal exposure. This condition resolved after discontinuing valproate therapy.[35][36]
Women who intend to become pregnant should switch to a different medication if possible, or decrease their dose of valproate.[37] Women who become pregnant while taking valproate should be warned that it causes birth defects and cognitive impairment in the newborn, especially at high doses (although valproate is sometimes the only drug that can control seizures, and seizures in pregnancy could have even worse consequences.) Studies have shown that taking folic acid can reduce the risk of congenital neural tube defects.[13]
Elderly
Valproate in elderly people with dementia caused increased sleepiness. More people stopped the medication for this reason. Additional side effects of weight loss and decreased food intake was also associated in one-half of people who become sleepy.[13]
Contraindications
Contraindications include:[38]
- Pregnancy
- Pre-existing acute or chronic liver dysfunction or family history of severe liver inflammation (hepatitis), particularly medicine related.
- Known hypersensitivity to valproate or any of the ingredients used in the preparation
- Urea cycle disorders
- Hepatic porphyria
- Hepatotoxicity[38]
- Mitochondrial disease[38]
- Pancreatitis[38]
- Porphyria[39]
Interactions
Valproate inhibits CYP2C9, glucuronyl transferase, and epoxide hydrolase and is highly protein bound and hence may interact with drugs that are substrates for any of these enzymes or are highly protein bound themselves.[38] It may also potentiate the CNS depressant effects of alcohol.[38] It should not be given in conjunction with other antiepileptics due to the potential for reduced clearance of other antiepileptics (including carbamazepine, lamotrigine, phenytoin and phenobarbitone) and itself.[38] It may also interact with:[13][38][40]
- Aspirin: may increase valproate concentrations. May also interfere with valproate's metabolism.
- Benzodiazepines: may cause CNS depression and there are possible pharmacokinetic interactions.
- Carbapenem antibiotics: reduces valproate levels, potentially leading to seizures.
- Cimetidine: inhibits valproate's metabolism in the liver, leading to increased valproate concentrations.
- Erythromycin: inhibits valproate's metabolism in the liver, leading to increased valproate concentrations.
- Ethosuximide: may increase ethosuximide concentrations and lead to toxicity.
- Felbamate: may increase plasma concentrations of valproate.
- Mefloquine: may increase valproate metabolism combined with the direct epileptogenic effects of mefloquine.
- Oral contraceptives: may reduce plasma concentrations of valproate.
- Primidone: may decrease pyrimidone clearance leading to toxicity.
- Rifampin: increases the clearance of valproate, leading to decreased valproate concentrations
- Warfarin: may increase warfarin concentration and prolong bleeding time.
- Zidovudine: may increase zidovudine serum concentration and lead to toxicity.
Overdose and toxicity
| Form | Lower limit | Upper limit | Unit |
| Total (including protein bound) |
50[41] | 125[41] | µg/mL or mg/l |
| 350[42] | 700[42] | μmol/L | |
| Free | 6[41] | 22[41] | µg/mL or mg/l |
| 35[42] | 70[42] | μmol/L |
Excessive amounts of valproic acid can result in sleepiness, tremor, stupor, respiratory depression, coma, metabolic acidosis, and death. In general, serum or plasma valproic acid concentrations are in a range of 20–100 mg/l during controlled therapy, but may reach 150–1500 mg/l following acute poisoning. Monitoring of the serum level is often accomplished using commercial immunoassay techniques, although some laboratories employ gas or liquid chromatography.[43] In contrast to other antiepileptic drugs, at present there is little favorable evidence for salivary therapeutic drug monitoring. Salivary levels of valproic acid correlate poorly with serum levels, partly due to valproate's weak acid property (pKa of 4.9).[44]
In severe intoxication, hemoperfusion or hemofiltration can be an effective means of hastening elimination of the drug from the body.[45][46] Supportive therapy should be given to all patients experiencing an overdose and urine output should be monitored.[13] Supplemental L-carnitine is indicated in patients having an acute overdose[47][48] and also prophylactically[47] in high risk patients. Acetyl-L-carnitine lowers hyperammonemia less markedly[49] than L-carnitine.
Mechanism of action
Although the mechanism of action of valproate is not fully understood,[38] it has recently been shown to protect against a seizure-induced reduction in phosphatidylinositol (3,4,5)-trisphosphate (PIP3) as a potential therapeutic mechanism.[50] In addition, its anticonvulsant effect has been attributed to the blockade of voltage-dependent sodium channels and increased brain levels of gamma-aminobutyric acid (GABA).[38] The GABAergic effect is also believed to contribute towards the anti-manic properties of valproate.[38] In animals, sodium valproate raises cerebral and cerebellar levels of the inhibitory synaptic neurotransmitter, GABA, possibly by inhibiting GABA degradative enzymes, such as GABA transaminase, succinate-semialdehyde dehydrogenase and by inhibiting the re-uptake of GABA by neuronal cells.[38] It also possesses histone deacetylase-inhibiting effects. The inhibition of histone deacetylase, by promoting more transcriptionally active chromatin structures, likely presents the epigenetic mechanism for regulation of many of the neuroprotective effects attributed to valproic acid. Intermediate molecules mediating these effects include VEGF, BDNF, and GDNF.[51][52]
Valproic acid has been found to be an antagonist of the androgen and progesterone receptors, and hence a non-steroidal antiandrogen and antiprogestogen, at concentrations much lower than therapeutic serum levels.[53] It was concluded that these actions are likely to be involved in the reproductive endocrine disturbances seen with valproic acid treatment.[53]
History
Valproic acid was first synthesized in 1882 by Beverly S. Burton as an analogue of valeric acid, found naturally in valerian.[54] Valproic acid is a carboxylic acid, a clear liquid at room temperature. For many decades, its only use was in laboratories as a "metabolically inert" solvent for organic compounds. In 1962, the French researcher Pierre Eymard serendipitously discovered the anticonvulsant properties of valproic acid while using it as a vehicle for a number of other compounds that were being screened for antiseizure activity. He found it prevented pentylenetetrazol-induced convulsions in laboratory rats.[55] It was approved as an antiepileptic drug in 1967 in France and has become the most widely prescribed antiepileptic drug worldwide.[56] Valproic acid has also been used for migraine prophylaxis and bipolar disorder.[57]

Valproate exists in two main molecular variants: sodium valproate and valproic acid without sodium (often implied by simply valproate). A mixture between these two is termed semisodium valproate. It is unclear whether there is any difference in efficacy between these variants, except from the fact that about 10% more of sodium vaproate is needed than valproic acid without sodium to compensate for the sodium itself.[88]
