If needed, medicines for anxiety and difficulty sleeping may be prescribed.

The purpose of this study is to help answer the following research question: Whether switching to duloxetine improves depressed mood when current treatment did not work well for patients with depression.
The following primary hypotheses will be tested: 1. During Step 1: Major Depressive Disorder (MDD) or Chronic Low Back Pain (CLBP) in < 40% of the initial 60 subjects treated with duloxetine (DUL) + Clinical Management(CM) during the first 8 weeks will respond (response is defined as a Montgomery Asberg Depression Rating Scale (MADRS) score </=9 and at least a 30% improvement in back pain as measured with the 20-point numeric rating scale. 2. During Step 2: More DUL+Problem Solving Therapy for Depression and Pain (PST-DP) than DUL+CM treated subjects will achieve response during the second 8 weeks, defined as a MADRS score </=9 and at least a 30% improvement in back pain as measured with the 2-point numeric rating scale. 3. Improvement in depression scores will be correlated with improvement in CLBP scores. The exploratory hypotheses to be tested are that: During Step 2: Compared to subjects treated with DUL+CM, subjects treated with DUL+PST-DP will have improved outcomes in: 1) disability, 2) sleep, 2) functioning/quality of life, 3) caregiver burden/depression, and 5) analgesic use.
The purpose of the study is to evaluate long-term safety and tolerability of Vortioxetine over a period of 52 weeks in patients with Major Depressive Disorder (MDD) having completed 8-week acute treatment.
Examination of the effect of zinc supplementation on imipramine therapy in major depression.
This is a multi-center, double blind, randomized, placebo-controlled, parallel group, flexible dose titration study conducted in centers in the USA and India. Following a washout period, subject will be treated with citalopram 20 mg once daily for 4 weeks, then with 40 mg once daily for 4 weeks. Subjects who tolerate 40 mg citalopram, but whose MADRS score is < 50% from baseline, but no lower than 17, will be considered partial or non-responders and will be randomized to receive either placebo or TC-5214 as add-on therapy. TC-5214 or placebo will be started at 2 mg daily (BID dosing), and be titrated based on tolerability and therapeutic response up to 8 mg daily. Approximately 560 subjects will enter the Open Label Phase and approximately 220 will enter the double blind phase of the study.
We hope to learn more about the biology of psychiatric illness with the hope of improving the diagnosis and treatment of such psychiatric conditions as major depression.
