Clinical Trial
Olanzapine therapy in treatment-resistant psychotic mood disorders: a long-term follow-up study.
Recent studies suggest a role for the atypical antipsychotic olanzapine in the acute treatment of psychotic mood disorders, but long-term data are unavailable. The purpose of this naturalistic study was to determine the long-term effectiveness and tolerability of olanzapine as add-on therapy in psychotic mood disorders. ⋯ Lack of response was the primary reason for discontinuation of add-on olanzapine in both groups. Mood symptoms predicted a better response to add-on olanzapine in patients with psychotic mood disorders on selective outcome measures. However, only 26% of the patients with psychotic mood disorders sustained a clinically meaningful mood-stabilizing effect with add-on olanzapine treatment at follow-up.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Efficacy of venlafaxine extended release in patients with major depressive disorder and comorbid generalized anxiety disorder.
A subset of patients with comorbid major depressive disorder and generalized anxiety disorder (GAD) was examined from a double-blind. placebo-controlled study comparing the efficacy and safety of venlafaxine extended release (XR) and fluoxetine. ⋯ This is the first evidence from a controlled study of the effectiveness of pharmacotherapy in patients with comorbid major depressive disorder and GAD. The delayed improvement in comorbid patients compared with noncomorbid patients suggests that a longer treatment period may be necessary in comorbid patients.
