DEPAKOTE CP vs VALPROIC ACID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Valproate increases GABA concentration in the brain by inhibiting GABA transaminase and succinic semialdehyde dehydrogenase. It also blocks voltage-gated sodium channels and T-type calcium channels.

250-500 mg orally twice daily, titrated by 250 mg/day every 3-7 days; maximum 60 mg/kg/day. Target trough serum concentration: 50-100 mcg/mL.
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.

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

Terminal elimination half-life is 9-16 hours (mean ~12 hours) in adults; prolonged in hepatic impairment, elderly, and neonates.
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).
Renal: 30-50% as glucuronide conjugates, 3% as unchanged drug; fecal: minimal; less than 3% excreted in bile.
Primarily hepatic metabolism (>95%), with less than 3% excreted unchanged in urine. Minor fecal excretion (~5%).
