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.
Zaleplon is a non-benzodiazepine hypnotic that selectively binds to the benzodiazepine type 1 (BZ1) receptor subtype on the gamma-aminobutyric acid (GABA) A receptor complex, potentiating GABA-mediated chloride ion influx and neuronal inhibition.
10 mg sublingually once daily at bedtime for insomnia; maximum 10 mg per night.
10 mg orally at bedtime; range 5-20 mg; maximum 20 mg per day.

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 approximately 1 hour (range 0.7–1.7 h) in healthy adults; elderly patients and those with hepatic impairment may have prolonged half-life (up to 2–3 h).
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%.
Approximately 83% of administered radioactivity is excreted in urine (with less than 1% as unchanged drug) and 17% in feces.
