2-Propylpentanoic acid Chemical Properties,Uses,Production


Valproate is a first- generation antiepileptic drug (AED) known with the proprietary brand names of Epilim® (Sanofi, Paris) and Episenta® (Desitin, Hamburg) in the UK and Depakote® (Sanofi, Paris) in the USA.

Generic formulation

MHRA/ CHM advice to minimize risk when switching patients with epilepsy between different manufacturers’ products (including generic products):


Monotherapy and adjunctive therapy of focal and generalized seizures.

Recommendations summarized from NICE (2012)
Treatment of acute mania associated with bipolar disorder.

Migraine prophylaxis (unlicensed).

Dose titration

600 mg daily divided into 1 or 2 doses, then increased by 150– 300 mg every 3 days; usual maintenance 1000– 2000 mg (or 20–30 mg/ kg) daily divided into 1 or 2 doses (max 2500 mg daily).

750 mg daily divided into 1 or 2 doses, adjusted according to response; usual maintenance 000– 2000 mg daily divided into 1 or 2 doses (doses greater than 45 mg/ kg daily require careful monitoring).

Plasma levels monitoring

Although plasma levels can be measured, and a therapeutic range has been postulated (40– 100 mg/ L), plasma valproate concentrations are not a useful index of efficacy. Therefore, routine monitoring is unhelpful.


Adverse effects

Valproate can be associated with adverse effects at the level the nervous system and other systems.


With AEDs With other drugs With alcohol/food
There are no specific foods that must be excluded from diet when taking valproate. Alcohol intake is not recommended during treatment with valproate.

Special populations

Hepatic impairment
Avoid if possible: hepatotoxicity and hepatic failure may occasionally occur (usually in first 6 months). Avoid in active liver disease.

Renal impairment
In patients with renal insufficiency, it may be necessary to decrease dosage of valproate. As monitoring of plasma concentrations may be misleading, dosage should be adjusted according to clinical monitoring.


Behavioural and cognitive effects in patients with epilepsy

The incidence of adverse psychiatric effects associated with valproate in patients with epilepsy is overall negligible (apart from reports of depression, irritability, and other behavioural symptoms in the context of encephalopathy). Cognitive difficulties have occasionally been reported in patients with epilepsy treated with valproate, especially affecting attention and memory functions.

Psychiatric use

Valproate is an effective mood stabilizer, licensed for the treatment of acute mania in patients with bipolar disorder. Although it has no formal indication, it is also considered a first- line agent for maintenance treatment in bipolar disorder. There is evidence suggesting efficacy of valproate in the treatment of hostility among patients with acute alcohol- associated hallucinosis or schizophrenia, and in impulsive/ aggressive behaviours, either in isolation or in the context of comorbid bipolar disorder or personality disorder. Available data show a limited efficacy of valproate in depressive disorders, schizophrenia, pathological gambling, as well as benzodiazepine/ cannabis/ cocaine dependence and acute alcohol withdrawal.

Chemical Properties

Antiepileptic; increases levels of -aminobutyric acid(GABA) in the brain. Anticonvulsant that also has efficacy as a mood stabilizer in bipolar disorder


Antiepileptic; Anticonvulsant that also acts as a mood stabilizer for those with bipolar disorder.


For 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 asso

General Description

Clear colorless liquid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

2-Propylpentanoic acid is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in 2-Propylpentanoic acid to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions. 2-Propylpentanoic acid is incompatible with bases, oxidizing agents and reducing agents. 2-Propylpentanoic acid is corrosive. .
