Study Endpoints

Primary Endpoints

Area Under the Concentration-time Curve From Time Zero Extrapolated to Infinite Time (AUC[0-infinity]) of Paroxetine Following Single Oral Dose in Healthy Chinese Participants Under Fed Condition
Pre-dose, 0.5 hour, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 10 hours, 12 hours, 16 hours, 24 hours, 36 hours, 48 hours, 72 hours and 96 hours post-dose in each treatment period

Blood samples were collected at designated time points. Pharmacokinetic (PK) parameters of Paroxetine were calculated using non-compartmental methods. Statistical analysis of PK parameters was done using mixed effect model for evaluation of bioequivalence (BE). Point estimate and associated adjusted 90% confidence interval (CI) of difference between both the treatments were provided for AUC(0-infinity).

AUC(0-infinity) of Paroxetine Following Single Oral Dose in Healthy Chinese Participants Under Fasting Condition
Pre-dose, 0.5 hour, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 10 hours, 12 hours, 16 hours, 24 hours, 36 hours, 48 hours, 72 hours and 96 hours post-dose in each treatment period

Blood samples were collected at designated timepoints. PK parameters of Paroxetine were calculated using non-compartmental methods. Statistical analysis of PK parameters was done using mixed effect model for evaluation of BE. Point estimate and associated adjusted 90% CI of difference between both the treatments were provided for AUC(0-infinity).

Area Under the Concentration-time Curve From Administration Extrapolated to the Last Time of Quantifiable Concentration (AUC[0-t]) of Paroxetine Following Single Oral Dose in Healthy Chinese Participants Under Fed Condition
Pre-dose, 0.5 hour, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 10 hours, 12 hours, 16 hours, 24 hours, 36 hours, 48 hours, 72 hours and 96 hours post-dose in each treatment period

Blood samples were collected at designated timepoints. PK parameters of Paroxetine were calculated using non-compartmental methods. Statistical analysis of PK parameters was done using mixed effect model for evaluation of BE. Point estimate and associated adjusted 90% CI of difference between both the treatments were provided for AUC(0-t).

AUC(0-t) of Paroxetine Following Single Oral Dose in Healthy Chinese Participants Under Fasting Condition
Pre-dose, 0.5 hour, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 10 hours, 12 hours, 16 hours, 24 hours, 36 hours, 48 hours, 72 hours and 96 hours post-dose in each treatment period

Blood samples were collected at designated timepoints. PK parameters of Paroxetine were calculated using non-compartmental methods. Statistical analysis of PK parameters was done using mixed effect model for evaluation of BE. Point estimate and associated adjusted 90% CI of difference between both the treatments were provided for AUC(0-t).

Maximum Observed Concentration (Cmax) of Paroxetine Following Single Oral Dose in Healthy Chinese Participants Under Fed Condition
Pre-dose, 0.5 hour, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 10 hours, 12 hours, 16 hours, 24 hours, 36 hours, 48 hours, 72 hours and 96 hours post-dose in each treatment period
