Completed · Phase 1
Conditions studied: Healthy
In brief
The purpose of this study is to determine if the relative difference in Pharmacokinetics (PK) between extensive metabolizers (EMs) and poor metabolizers (PMs) is the same with desvenlafaxine SR and venlafaxine ER when a single dose is administered.
