🌿 What is Divalproex Sodium (Dicorate ER)?
Dicorate ER delivers Divalproex Sodium, a stable compound of sodium valproate and valproic acid, formulated for extended release over 24 hours. This delivery system maintains steady therapeutic blood levels, reducing peak-related side effects such as dizziness and gastrointestinal discomfort. As a result, patients benefit from improved seizure control, mood stabilization in bipolar disorder, and effective migraine prevention with once-daily dosing.
Clinical trials have demonstrated that extended-release Divalproex provides similar efficacy to immediate-release formulations but with enhanced tolerability and adherence. Moreover, the ER form minimizes fluctuations in plasma concentration, leading to fewer breakthrough seizures and mood swings.
For authoritative prescribing details and safety information, refer to the FDA label for Depakote ER and the Drugs.com monograph. Additional guidance is also available through the NHS Medicines A–Z and the WHO Essential Medicines List.
