About
Divalproex sodium, often referred to as valproate, is a broad-spectrum anticonvulsant medication widely used in the treatment of epilepsy, bipolar disorder, and for the prophylaxis of migraine headaches. It works through multiple mechanisms, including increasing brain levels of gamma-aminobutyric acid (GABA), blocking voltage-gated sodium channels, and modulating T-type calcium channels. These actions contribute to its ability to stabilize neuronal membranes and reduce abnormal electrical activity in the brain, thereby preventing seizures and stabilizing mood.
The "OD" (Once Daily) formulation indicates an extended-release preparation, designed to provide consistent therapeutic levels throughout the day, which can improve patient adherence and reduce the incidence of dose-related side effects. Due to its complex pharmacological profile, regular monitoring of liver function, platelet counts, and drug levels is crucial during treatment. It is a highly effective medication but requires careful management due to its potential side effects.
