Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Zolpidem is a non-benzodiazepine hypnotic that acts as a positive allosteric modulator of GABA-A receptors, specifically binding to the alpha1 subunit, enhancing chloride ion conductance and producing sedative effects.
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.
10 mg sublingually once daily at bedtime for insomnia; maximum 10 mg per night.
250 mg orally three times daily.

Terminal elimination half-life is approximately 2 hours (range 1.5–3 hours). This short half-life supports its use for sleep induction with minimal next-day residual effects.
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.
Primarily renal, with approximately 80% of the dose excreted in urine as metabolites (mostly glucuronide conjugates) and less than 1% as unchanged drug. Fecal excretion accounts for <15%.
Renal excretion accounts for >90% of elimination, primarily as unchanged drug via glomerular filtration and tubular secretion. Biliary/fecal excretion is minimal (<5%).
