Valproic Acid Introduction

Valproic Acid (VPA), also known as divalproex sodium, is a medication used for the treatment of seizures, bipolar disorder, migraine prophylaxis, and other medical conditions. It is a short-chain fatty acid and is believed to work by increasing the amount of GABA (a neurotransmitter) in the brain. Valproic Acid has also been found to possess anti-inflammatory and neuroprotective effects.

Uses for Valproic Acid

Valproic Acid is used primarily for the treatment of certain types of seizure disorders, including typical and atypical absence seizures, tonic-clonic (grand mal) seizures, myoclonic seizures, and mixed seizure patterns. It can also be used to treat migraine prophylaxis, manic episodes associated with bipolar disorder, cluster headaches, and adjunctively to treat depression. In addition, its anti-inflammatory and neuroprotective properties allow it to be used in the treatment of multiple sclerosis, as well as neurodegenerative diseases such as Alzheimer’s and Huntington’s disease.

Mechanism of Action

Valproic Acid is believed to work, in part, by increasing the amount of gamma–aminobutyric acid (GABA) in the brain. GABA is an inhibitory neurotransmitter, which means it helps to reduce the activity of neurons in the brain. Valproic Acid also increases dopamine concentrations, which may also be beneficial in reducing seizure activity.

How Long Does it Take to Work?

Valproic Acid usually works within a few days to weeks, depending on the condition being treated. It is important to note that everyone responds differently to medications, and it is possible that some people may not experience the full effects even after several weeks of taking the medication.
