Overview
Brief Summary
The primary objectives are to investigate the effect of atomoxetine on impulsivity after single dose and at steady state measured by the total score of Barrett Impulsiveness Scale version 11 (BIS-11) and Short Urgency, Perseverance, Premeditation, and Sensation Seeking-Positive Urgency Impulsive Behavior Scale (S-UPPS-P) Impulsive Behavior Scale. The secondary objective is to evaluate the safety of atomoxetine.

Arms & Interventions
Atomoxetine
Day 1 and Day 8: After fasting for at least 10 hours overnight, participants received a single dose of Atomoxetine consisting of two 40 mg capsules (totaling 80 mg) in the morning at the trial site. Day 2 to Day 7: Participants took a single dose of Atomoxetine consisting of one 40 mg capsule in the morning at home. Day 9 to Day 14: Participants took a single dose of Atomoxetine consisting of two 40 mg capsules (totaling 80 mg) in the morning at home.
Intervention: Zentiva®
Placebo (matching Atomoxetine)
Day 1 and Day 8: After fasting for at least 10 hours overnight, participants received a single dose of placebo (matching Atomoxetine) in the morning at the trial site. Day 2 to Day 7: Participants took a single dose of placebo (matching Atomoxetine) in the morning at home. Day 9 to Day 14: Participants took a single dose of placebo (matching Atomoxetine) in the morning at home.
Intervention: Placebo
Outcomes
Primary Outcomes
Change From Baseline in Total Score of Barratt Impulsiveness Questionnaire v.11 (BIS-11) at Steady State (at Day 14)
Time Frame: Analysis based on the observation period: days 0 to 14, change from baseline calculated for Day 14.
The BIS-11 evaluates impulsiveness via 30 items scored on a 4-point scale (Rarely/Never = 1; Occasionally = 2; Often = 3; Almost Always/Always = 4). Total scores range from 30 (least impulsive) to 120 (most impulsive), calculated by summing item scores. Higher scores indicate greater impulsiveness. The data used in the analysis of covariance (ANCOVA) were estimated regardless of whether participants used rescue or other concomitant medications, or experienced nausea/vomiting. For participants who discontinued treatment early (receiving \<90% of planned doses), their data were included in the analysis only up to the point of discontinuation. Reported summary data was based on an ANCOVA with the BIS-11 score at baseline as a covariate and the treatment arm as fixed factor.
Change From Baseline in Total Score of Short Urgency, Perseverance, Premeditation, and Sensation Seeking-Positive Urgency Impulsive Behavior Scale (S-UPPS-P) Impulsive Behavior Scale After Single Dose (at Day 1)
Time Frame: Analysis based on the observation period: days 0 to 1, change from baseline calculated for Day 1.
The S-UPPS-P assesses impulsivity across five traits using 20 items scored on a 4-point scale (Agree Strongly = 1; Agree Some = 2; Disagree Some = 3; Disagree Strongly = 4). Total scores range from 20 (least impulsive) to 80 (most impulsive), calculated by summing item scores. Higher scores indicate greater impulsiveness. The data used in the analysis of covariance (ANCOVA) were estimated regardless of whether participants used rescue or other concomitant medications, or experienced nausea/vomiting. For participants who discontinued treatment early (receiving \<90% of planned doses), their data were included in the analysis only up to the point of discontinuation. Reported summary data was based on an ANCOVA with the S-UPPS-P score at baseline as a covariate and the treatment arm as fixed factor.
