Safety and Efficacy of Venlafaxine XR in Elderly Patients With Major Depression

Study Overview
=================
Brief Summary
-----------------
This research study is to evaluate the safety and usefulness of venlafaxine-XR in the treatment of major depression in the elderly.

Detailed Description
-----------------
The primary objective of this pilot study is to evaluate the safety of venlafaxine extended release formulation (XR) in the treatment of geriatric non-psychotic depression. This pilot study's specific aims are to assess the safety of venlafaxine XR in the geriatric population, to estimate the response rate of older depressed subjects treated under open conditions and to evaluate pharmacokinetic characteristics that may impact on safety and outcome.
