BACKGROUND To compare venlafaxine and selective serotonin reuptake inhibitors (SSRIs; fluoxetine, sertraline, paroxetine, fluvoxamine, and citalopram) in the treatment of depression. METHODS AND MATERIALS Meta-analysis of 34 randomized, double-blind studies identified by a worldwide search of all research sponsored by Wyeth Pharmaceuticals through January(More)
BACKGROUND Serotonergic and adrenergic enhancement may be synergistic and more effective than serotonergic enhancement alone in treating depression. The dual serotonin-norepinephrine reuptake inhibitor (SNRI) venlafaxine is a dual reuptake inhibitor that may therefore offer greater efficacy than selective serotonin reuptake inhibitors (SSRIs). METHODS(More)
BACKGROUND Major depression is often chronic and recurrent, yet most long-term therapeutic trials are not adequately designed to assess antidepressant efficacy in recurrence prevention. Long-term efficacy and safety of prophylactic venlafaxine treatment were evaluated in outpatients with recurrent major depression. METHOD Patients with a history of(More)
BACKGROUND We examined the efficacy and safety of three different dosages of venlafaxine hydrochloride (75, 225, and 375 mg/day) in a multicenter, randomized, double-blind, placebo-controlled, four-group study. METHOD Outpatients, 18 to 65 years old, who met DSM-III criteria for major depression were included (N = 358 randomized; 194 completed). Of the(More)
This 12-week, double-blind, placebo-controlled study evaluated the efficacy and safety of venlafaxine as first-line therapy for the treatment of major depression and major depression associated with anxiety in 384 adult outpatients. Fixed total daily dosages of 75, 150, and 200 mg of venlafaxine were administered in a twice-a-day regimen. Primary efficacy(More)
Venlafaxine is the first member of a novel class of antidepressants that inhibits the reuptake of both serotonin and norepinephrine. Clinical trials of venlafaxine have demonstrated its efficacy and safety in the treatment of patients diagnosed with major depression. Because patients who have depression also often have anxiety, recent investigations have(More)
Unidimensional subscales for assessment of major depression may be more sensitive to antidepressant drug effects than the Hamilton Depression Rating Scale (HAM-D). To further examine this possibility, we analyzed pooled data from eight comparable, well-controlled clinical trials of venlafaxine and compared such subscales and the 17-item HAM-D (HAM-D(17))(More)
The objective of this study was to compare venlafaxine and fluoxetine with placebo in treating major depressive disorder with melancholic features. Adult inpatients with Diagnostic and Statistical Manual of Mental Disorders, fourth edition major depressive disorder with melancholia and 21-item Hamilton Depression Rating Scale (HAM-D₂₁) scores > or =24(More)
RATIONALE Few randomized, placebo-controlled trials have evaluated the comparative efficacy and tolerability of more than one pharmacological agent for panic disorder. OBJECTIVES The primary objective of this study was to compare the efficacy and tolerability of venlafaxine extended release (ER) with placebo in treating panic disorder. Secondary(More)
OBJECTIVE This study evaluated the efficacy and tolerability of desvenlafaxine succinate (desvenlafaxine) in the treatment of major depressive disorder (MDD). METHOD In this 8-week, multicenter, randomized, double-blind, placebo-controlled trial, adult outpatients (aged 18-75 years) with a primary diagnosis of MDD (DSM-IV criteria) were randomly assigned(More)
