Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Eszopiclone 3 mg tablet	Drug: Eszopiclone 3 mg; Group A Period I, Group B Period II: Eszopiclone 3 mg tablet taken orally (po) with water as a single administration in the morning after fasting >=10 hours. Except for the water taken with the drug, participants were not allowed any food/ drink from 10 hours before until 4 hours after administration of drug. Except for the water taken with the study drug, participants were not permitted to drink water from 1 hour before until 1 hour after administration of drug. Group B Period III: Eszopiclone 3 mg tablet taken po with water as a single administration in the morning 30 minutes after the start of breakfast. Except for the food/ drink at breakfast and the water taken with the study drug, participants were not allowed any food or drink from 10 hours before until 4 hours after administration of the drug. Except for the food/ drink at breakfast & the water taken with the study drug, participants were not permitted to drink water from 1 hour before until 1 hour after administration.
Experimental: Eszopiclone 1 mg tablet	Drug: Eszopiclone 1 mg; Group A Period II, Group B Period I: Eszopiclone three 1 mg tablets (total: 3 mg) taken orally with water as a single administration in the morning after fasting 10 or more hours. Except for the water taken with the study drug, participants were not allowed any food or drink (except water) from 10 hours before until 4 hours after administration of the study drug. Except for the water taken with the study drug, participants were not permitted to drink water from 1 hour before until 1 hour after administration of the study drug.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetic Parameter (Bioequivalence): Maximal Drug Concentration (Cmax)	Pharmacokinetic parameter: maximal drug concentration (Cmax) was measured in order to confirm bioequivalence. Cmax was measured in nanograms per milliliter (ng/mL). Blood sampling was calculated immediately before administration of the study drug and 24 hours after administration of the study drug (0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12, 24 hours post-dose).	immediately before administration & 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12, 24 hours post-dose
Pharmacokinetic Parameter (Bioequivalence): Area Under the Plasma Concentration- Time Curve From Time 0 to Time 24 Hours (AUC[0-24])	Pharmacokinetic parameter: Area under the plasma concentration- time curve from time 0 (administration of the drug) to time 24 hours was measured in order to confirm bioequivalence. AUC was measured in nanogram hours per milliliter (ng*h/mL). Blood sampling was calculated immediately before administration of the study drug and 24 hours after administration of the study drug (0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12, 24 hours post-dose).	immediately before administration & 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12, 24 hours post-dose
Pharmacokinetic Parameter (Food Effect): Maximal Drug Concentration (Cmax)	Pharmacokinetic parameter: maximal drug concentration (Cmax) was measured in order to investigate the effect of food. Cmax was measured in nanograms per milliliter (ng/mL) and was measured under fasted and fed conditions. Blood sampling was calculated immediately before administration of the study drug and 24 hours after administration of the study drug (0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12, 24 hours post-dose).	immediately before administration & 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12, 24 hours post-dose
Pharmacokinetic Parameter (Food Effect): Area Under the Plasma Concentration- Time Curve From Time 0 to Time 24 Hours (AUC[0-24])	Pharmacokinetic parameter: Area under the plasma concentration- time curve from time 0 (administration of the drug) to time 24 hours was measured in order to investigate the effect of food. AUC was measured in nanogram hours per milliliter (ng*h/mL) and was measured under fasted and fed conditions. Blood sampling was calculated immediately before administration of the study drug and 24 hours after administration of the study drug (0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12, 24 hours post-dose).	immediately before administration & 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, 12, 24 hours post-dose
