Abstract
Valproate is a simple branched-chain carboxylic acid. It was first used as an organic solvent, before it was discovered as an effective anti-convulsant in the 1960s. Although valproate has approval by most agencies for treatment of acute mania in bipolar disorder only, it is widely used off-label as maintenance treatment as well as for a number of other psychiatric disorders and symptoms in clinical practice. Available studies, including a limited number of randomized clinical trials, support the use of valproate for treatment in acute mania, although it has not been proven to be superior to other treatment options such as lithium or atypical antipsychotics. There is also limited evidence for its (off-label) use as long-term treatment to prevent relapses in bipolar disorders; however, valproate is also not superior to lithium in this indication either. During valproate treatment, a number of side effects may occur with rare but potentially life-threatening toxic effects. In particular, its teratogenic effects make it non-suitable for female patients in child-bearing age. When used in combination with other medications, inhibition of cytochrome enzymes and UDP-glucuronosyltransferases needs to be considered.
