Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Barbiturate-like sedative-hypnotic; acts on GABA-A receptors to enhance inhibitory neurotransmission, causing CNS depression.
Valproate increases gamma-aminobutyric acid (GABA) concentrations in the brain either by inhibiting GABA transaminase or by increasing glutamic acid decarboxylase activity, thereby enhancing inhibitory neurotransmission.
500 mg orally at bedtime, maximum 1 g per day; for sedation, 250 mg 3 times daily after meals.
250 mg orally three times daily.

Terminal elimination half-life is 4-10 hours in healthy adults; prolonged in elderly and patients with hepatic impairment, increasing to 12-20 hours.
Terminal elimination half-life is 2-4 hours in adults with normal renal function; prolonged to 10-20 hours in severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
Renal (accounting for approximately 80% of elimination, primarily as glucuronide conjugates and unchanged drug); biliary/fecal (minor, about 10%).
Renal excretion accounts for >90% of elimination, primarily as unchanged drug via glomerular filtration and tubular secretion. Biliary/fecal excretion is minimal (<5%).
