Brief summary

The purpose of this study is to assess the pharmacokinetics (absorption, breakdown and elimination from the body), safety and tolerability of Brisdelle (paroxetine mesylate) Capsules 7.5 mg when given as a single dose and multiple doses.

Detailed description

This study is for research only and is not designed to treat a medical condition.

Interventions

All subjects will receive Brisdelle (paroxetine mesylate) Capsules 7.5 mg, first as a single dose and then, following a five-day wash-out period, once per day for 14 days.

Outcome results

Primary

Accumulation Index Multiple Dose Pharmacokinetics of Brisdelle (Paroxetine Mesylate) Capsules 7.5 mg at Day 19

Accumulation Index is the ratio of AUC 0-24 after multiple doses versus a single dose. It is the increase in drug plasma concentration after multiple dosing until a steady state is reached. In this case the steady state Accumulation Index was calculated at Day 19. Accumulation Index is calculated at the end of the dosing period.
