Description
🧠⚡💊 Sodium Valproate 333mg + Valproic Acid 145mg Tablet: High-Strength Control for Epilepsy & Mood Disorders
The combination of Sodium Valproate 333mg and Valproic Acid 145mg delivers a total valproate equivalent of 500mg, making it a high-strength formulation ideal for the treatment of moderate to severe epilepsy, bipolar disorder, and migraine prophylaxis. This dual-action formulation provides both immediate and sustained release, offering superior control over seizures and mood fluctuations in various neurological and psychiatric conditions.
🔬 Mechanism of Action
Sodium Valproate and Valproic Acid work synergistically to increase the concentration of gamma-aminobutyric acid (GABA) in the brain—a key inhibitory neurotransmitter responsible for calming neuronal activity. The mechanism includes:
-
Enhancement of GABA synthesis
-
Inhibition of GABA breakdown
-
Blocking of voltage-gated sodium and T-type calcium channels, stabilizing nerve activity
This combination exerts a broad-spectrum antiepileptic effect and also works as a central mood stabilizer.
