What does valproate mean?
Valproate is the anion of valproic acid and, in clinical usage, a name for the valproic-acid drug compound, especially sodium valproate. Once mainly associated with seizure control, it is also used as a mood stabilizer in bipolar disorder and, in some settings, for other neurological conditions. Prescribing it requires attention to formulation, blood concentration, interactions, and risks during pregnancy; the word therefore belongs mainly to medicine and pharmacology rather than everyday conversation. In chemical writing, “valproate” identifies the negatively charged form of the molecule, whereas “valproic acid” identifies its neutral acid form. In prescriptions and clinical discussion, the shorter term may refer to either, and specific salts are named separately. Knowing the distinction helps readers interpret blood-test results, treatment discussions, and safety warnings accurately. Its derivation from the French name for valproic acid reflects the compound's twentieth-century development as an anticonvulsant.
nounAn anion or salt of valproic acid, especially sodium valproate, used chiefly as an anticonvulsant and mood stabilizer. In clinical shorthand, the term may also refer to valproic acid itself.
- The anion of valproic acid or a salt of that acid; in medicine, especially sodium valproate, used as an antiseizure drug and mood stabilizer.
"The clinician adjusted the valproate level after reviewing the patient's blood tests."
"The clinician increased the valproate level after reviewing her blood tests."
"Sodium valproate is widely used to control seizures."
The plural is uncommon and can refer to different salts or compounds of valproic acid.
"The researchers compared the absorption of two valproates."
A 1963 observation of valproic acid's anticonvulsant effect led to one of modern epilepsy's foundational medicines.

Etymology of valproate
In English chemical nomenclature, valproate combines the French-derived base valpro- with the suffix -ate, denoting an anion or salt of valproic acid. The related name valproic acid comes from French acide valproïque; although the acid was synthesized in the nineteenth century, its anticonvulsant use was reported in the 1960s and led to its development as a major epilepsy treatment. Names such as sodium valproate and divalproex belong to the same modern chemical word family but do not necessarily denote identical formulations.

How valproate is actually used
This is primarily technical and clinical vocabulary rather than everyday usage. In medical writing, valproate may refer broadly to valproic acid or sodium valproate, so the intended substance should be clear from context.
Easily confused with valproate
Valproic acid is the neutral acid form of the compound, whereas valproate strictly denotes its anion or a salt such as sodium valproate, although clinical usage sometimes treats the terms interchangeably.
