Rapid gas chromatographic assay for monitoring valproic acid and valpromide in plasma. 1984

M Bialer, and M Friedman, and A Rubinstein

A gas chromatographic (GC) method for monitoring valproic acid and valpromide in plasma was developed. The procedure involved a single solvent extraction of drugs from acidified plasma samples, followed by a GC injection of the organic phase. This rapid, sensitive, specific, and reproducible method is a key factor in pharmacokinetic and stability studies of valpromide. Pharmacokinetic application of the new GC method is presented by a simultaneous plasma monitoring of valpromide and valproic acid levels obtained after intravenous administration of valpromide to a dog.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D014635	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.
