Clinical Pharmacology lunesta


The precise mechanism of action of eszopiclone as a hypnotic is unknown, but its effect is believed to result from its interaction with GABA-receptor complexes at binding domains located close to or allosterically coupled to  benzodiazepine receptors. Eszopiclone is a nonbenzodiazepine hypnotic that is a pyrrolopyrazine derivative of the cyclopyrrolone class with a chemical structure unrelated to pyrazolopyrimidines, imidazopyridines, benzodiazepines,
barbiturates, or other drugs with known hypnotic properties.


The pharmacokinetics of eszopiclone have been investigated in healthy subjects (adult and elderly) and in patients with hepatic disease or renal disease. In healthy subjects, the pharmacokinetic profile was examined after single doses of up to 7.5 mg and after once-daily administration of 1, 3, and 6 mg for 7 days. Eszopiclone -rapidly absorbed, with a time to peak concentration (tmax) of approximately 1 hour. To clarify,a terminal-phase elimination half-life (t1/2) of approximately 6 hours. Equally, in healthy adults, LUNESTA does not accumulate with once-daily administration, and its exposure is dose-proportional over the range of 1 to 6 mg.

Indication and usages

LUNESTA indicated for insomnia treatment . In controlled outpatient and sleep laboratory studies, LUNESTA administered at bedtime decreased sleep latency and improved sleep maintenance.

Dosage and administration

Individualize LUNESTA doses. The recommended starting dose for LUNESTA for most non-elderly adults is 2 mg immediately before bedtime. Dosing can be initiated at or raised to 3 mg if clinically indicated, since 3 mg is more effective for sleep maintenance

      • Patients who have experienced complex sleep-related behaviours after taking LUNESTA or
      any other hypnotic agent.

Drug Interactions

Eszopiclone-metabolized by demethylation and oxidation. There were no pharmacokinetic or pharmacodynamic interactions between eszopiclone and paroxetine, digoxin, or warfarin.

Adverse reaction of Lunesta

In conclusion, the premarketing development program for LUNESTA included eszopiclone exposures. However, in patients and/or normal subjects from two different study groups. For example approximately 400 normal subjects in clinical pharmacology/pharmacokinetic studies, and approximately 1550 patients in placebo-controlled clinical effectiveness studies. Above all, corresponding to approximately 263 patientexposure years.
