Open Label Drug Interaction Study Evaluating Desvenlafaxine Succinate Sustained Release (DVS SR) 100mg On The Pharmacokinetics Of Aripiprazole When Coadministered To Healthy Subjects

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.
