DEPAKOTE ER vs VALPROIC ACID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases GABAergic activity by inhibiting GABA transaminase and succinate semialdehyde dehydrogenase; blocks voltage-gated sodium and T-type calcium channels; reduces glutamate release.
Increases GABA concentration in the brain by inhibiting GABA transaminase and succinic semialdehyde dehydrogenase; also blocks voltage-gated sodium channels and T-type calcium channels.
500-1000 mg orally once daily; usual maximum dose 60 mg/kg/day.
Initial: 10-15 mg/kg/day orally (divided 2-3 times), increase by 5-10 mg/kg/week; maintenance: 30-60 mg/kg/day. IV infusion: same oral dose, rate ≤20 mg/min.

Terminal elimination half-life is approximately 20 hours (range 10-60 hours); clinical context: extended-release formulation allows once-daily dosing, steady-state achieved in 4-5 days
Clinical Note
moderateValproic acid + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Valproic acid is combined with Fluticasone propionate."
Clinical Note
moderateValproic acid + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Valproic acid."
Clinical Note
moderateValproic acid + Cyclosporine
"The metabolism of Cyclosporine can be decreased when combined with Valproic acid."
Clinical Note
moderateValproic acid + Fluconazole
Terminal elimination half-life is 9–16 hours in adults; shorter in children (6–9 hours) and longer in neonates (20–30 hours), elderly, or hepatic impairment (up to 18 hours).
Primarily renal (30-50% as glucuronide conjugates, <3% as unchanged drug); minor fecal (10-20%)
Primarily hepatic metabolism (>95%), with less than 3% excreted unchanged in urine. Minor fecal excretion (~5%).
