- History of being a nonsmoker for at least 1 year.

- Subjects have to be either extensive CYP2D6 metabolizers with a normal complement of 1 or 2 fully active enzyme gene alleles or poor CYP2D6 metabolizers (lack of active enzyme gene alleles) via genetic testing of a blood sample.

Show details


- Presence or history of any significant cardiovascular, hepatic, renal, respiratory,
gastrointestinal, endocrine, immunologic, dermatologic, hematologic, neurologic, or
psychiatric disease or any severe conditions of the ears, eyes or throat (such as
glaucoma or increased intraocular pressure).


- Known or suspected alcohol abuse or consumption of more than 2 standard units per day

Brief Title  ICMJE Study Evaluating the Pharmacokinetics of Venlafaxine Extended-Release (ER) and Desvenlafaxine Succinate Sustained-Release (DVS SR) 50 mg in Healthy Subjects
Official Title  ICMJE A Randomized, Open-Label, Two-Period, Parallel Group, Crossover Study to Evaluate the Pharmacokinetics of Venlafaxine Extended-Release and DVS SR in Healthy Subjects Who Are Extensive or Poor Cytochrome P450 2D6 Substrate Metabolizers
Brief Summary 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.
