About
VALGRESS-CR, a controlled-release formulation of valproic acid, is a versatile medication used in the management of epilepsy, bipolar disorder, and for the prophylaxis of migraine headaches. Its complex mechanism of action is thought to involve multiple pathways, including increasing the brain's levels of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, by inhibiting its degradation and enhancing its synthesis. Additionally, valproate is believed to modulate voltage-gated sodium channels and T-type calcium channels, further contributing to its anticonvulsant and mood-stabilizing effects. The controlled-release formulation is designed to provide sustained drug levels, which helps to reduce the frequency of dosing and minimize fluctuations in plasma concentrations, potentially leading to fewer side effects and improved patient adherence. It is a cornerstone in the treatment of several neurological and psychiatric conditions.
