Overview

Brief Summary

The goal of this study is to evaluate the effect of multiple doses of Desvenlafaxine Sustained Release (SR) on the pharmacokinetics of Aripiprazole when coadministered to healthy adult subjects. This study will also evaluate the safety and tolerability of Desvenlafaxine SR and Aripiprazole when coadministered to healthy adult subjects.

Primary Outcomes

Time Frame: Period 1 / Day 1: 0, 0.5, 1, 2, 3, 4, 6, 8, 12, 16, 24, 48, 72, 120, 168, 216, 264, and 312 hours after dosing; Period 2 / Day 7: 0, 0.5, 1, 2, 3, 4, 6, 8, 12 and 16 hours after dosing; also 0 hour Period 2 / Day 8, 9, 10, 12, 14, 16, 18, and Day 20

Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - ∞). It is obtained from AUC (0 - t) plus AUC (t - ∞); measured as nanograms multiplied by hours divided by milliliters (ng\*hr/mL).
