🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Sodium Valproate exerts its therapeutic effects through multiple mechanisms. Its primary action is believed to involve increasing brain concentrations of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, by inhibiting GABA transaminase and succinic semialdehyde dehydrogenase, and possibly by enhancing glutamic acid decarboxylase activity. Additionally, it blocks voltage-gated sodium channels, reducing neuronal excitability. It may also affect the metabolism of dopamine and serotonin. These combined actions help stabilize electrical activity in the brain, preventing seizures and stabilizing mood.

Dosage Information
| Adult Dosage | The dosage of this medicine must be individualized by a qualified clinician based on the indication, age, weight, renal and hepatic function, and concomitant medications. For epilepsy, the usual starting dose is 10-15 mg/kg/day, increased gradually to a maintenance dose of 20-30 mg/kg/day in divided doses. For bipolar disorder, the starting dose is often 750 mg/day in divided doses, adjusted based on response. For migraine prophylaxis, the dose ranges from 500 to 1000 mg/day. Always follow your doctor's prescription and do not adjust the dose without medical advice. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children. |

| Renal Impairment | Dose adjustment may be necessary in patients with renal impairment. Sodium Valproate is primarily excreted in urine, and accumulation may occur. Consult a clinician for individualized dosing. |
| Hepatic Impairment | Sodium Valproate is contraindicated in patients with significant hepatic impairment. In patients with mild hepatic impairment, dose reduction and close monitoring are required. Consult a clinician for individualized dosing. |
| Maximum Daily Dose | The maximum daily dose is typically 60 mg/kg/day, but this must be individualized by a qualified clinician. Do not exceed the prescribed dose. |
