valproic acid and Encephalopathy, Toxic

valproic acid has been researched along with Encephalopathy, Toxic in 94 studies

Valproic Acid: A fatty acid with anticonvulsant and anti-manic properties that is used in the treatment of EPILEPSY and BIPOLAR DISORDER. 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-GATED SODIUM CHANNELS.
valproic acid : A branched-chain saturated fatty acid that comprises of a propyl substituent on a pentanoic acid stem.
