Acute and Continuation Treatment Adequacy with Venlafaxine Extended Release Compared with Fluoxetine

Abstract

Patients newly prescribed venlafaxine XR were at least 3 times more likely to achieve treatment adequacy for 84 and 180 days compared with those newly prescribed fluoxetine. Treatment adequacy as a proxy for optimal treatment may be an important factor to consider when selecting an antidepressant drug.
