Brief summary

The primary purpose of the study is to evaluate the potential effect of paroxetine on QTc interval following escalating doses in healthy participants. Participants with no history of cardiac abnormalities or mood disorders will be enrolled. During the study, participants will take paroxetine at three incremental dose levels. Participants will attend the clinic at screening, baseline, at the end of each dose level administration week, and a final study exit visit. While on treatment outside of clinic visits, participants will be followed-up via video-call. A concentration-QTc analysis will assess any potential correlation between paroxetine plasma concentration and QTc prolongation. In addition, the occurrence of any side-effects will be compared between on and off treatment.

Time frame: Baseline (Day -1); 0.25 Hours Pre-dose on Day 1; 1, 2, 3, 4, 4.5, 5, 5.5, 6, 8, 10, 12 Hours Post-dose on Day 1

Population: Pharmacodynamic Population included all participants in the Safety Population who had at least 1 non-missing ECG assessment. Only those participants who were measured and analyzed (i.e., contributed data reported in the table) were included in the 'Overall Number of Participants Analyzed' field.
