Active clinical trials for "Depressive Disorder, Major"

The purpose of this study is the evaluation of remission rate between escitalopram 20 mg and 30 mg in patients with major depressive disorder.

Purpose : This study will determine whether MK-0657, a selective NR2B Antagonist, can quickly improve symptoms of depressed mood, psychomotor retardation, poor motivation and reduced enjoyment of things in patients with major depression. MK-0657 decreases the activity of a brain receptor called NMDA, which the chemical glutamate binds to, possibly inducing a rapid antidepressant response. People between 18 and 55 years of age who have major depression of at least 4 weeks' duration and have not been helped by two antidepressants approved for major depression may be eligible for this study. Women who are able to have children are excluded. Participants are admitted to the NIH Clinical Center for two study phases, as follows. Phase I (1 to 2 weeks): Patients are tapered off their current medications. Phase II (7 weeks): Patients are randomly assigned to take either MK-0657 or placebo (look-alike capsules with no active ingredient) by mouth for 12 days. At some point during the second part this phase, patients who had been taking MK-0657 are switched over to placebo and those who had been taking placebo are switched to MK-0657. Participants undergo the following procedures during the study:Physical examination twice (at the beginning and at the end of the study) Electrocardiogram (ECG) four times Blood tests about six times Rating scales up to 28 times to assess the effects of MK-0657 on mood and thinking Blood pressure measurements three times a day. Study examines the effectiveness of a new medication, targeting a system called glutamate, will improve depression when compared with placebo.

This open-label study will assess the medication Geodon® (Ziprasidone) in pediatric patients, aged 13-17, diagnosed with psychotic disorder. Eligible adolescents will receive Geodon® for 7 weeks and stay at the NYSPI Children's Day Unit (CDU) during the day. If clinically appropriate, they may also stay at the New York State Psychiatric Institute (NYSPI) Schizophrenia Research Unit (SRU) inpatient facility.

To evaluate the long-term safety of desvenlafaxine sustained release (DVS-233SR) during open-label treatment of outpatients with major depressive disorder (MDD).

This study will assess the safety, tolerability and efficacy of desvenlafaxine succinate sustained release (DVS SR) in subjects with major depressive disorder.

To evaluate the antidepressant effect of adjunctive treatment with Eszopiclone in subjects receiving venlafaxine for the treatment of Major Depressive Disorder (MDD).

The purpose of this study is to determine whether a home-based intervention matched to stage of change (readiness) for using effective methods to prevent or reduce depression can improve depression outcomes in primary care.

Desvenlafaxine succinate (DVS) is a potent and selective serotonin and norepinephrine reuptake inhibitor (SNRI). This study will investigate the safety, efficacy, and tolerability of DVS SR versus escitalopram in women with major depressive disorder (MDD) who are postmenopausal.

This concurrent, two-part study will: I) Using overnight sleep recordings, evaluate the short- and long-term sleep-promoting effects of the antidepressant mirtazapine (Remeron) in patients who have been prescribed this medication for major depressive disorder and sleep disruption. II) Investigate the psychomotor performance of depressed patients using driving simulation testing before and during treatment with mitrazapine.

Bipolar disorder (BD) is a common and severe psychiatric illness. Drug and alcohol abuse are very common in people with BD and other mood disorders and are associated with increased rates of hospitalization, violence towards self and others, medication non-adherence and cognitive impairment. However, few studies have investigated the treatment of dual-diagnosis patients as substance use is frequently an exclusion criterion in clinical trials of patients with BD. To address this need, we have developed a research program that explores the pharmacotherapy of people with BD and substance related-disorders. A potentially very interesting treatment for BD is citicoline. Some data suggest that this supplement may stabilize mood, decrease drug use and craving, and improve memory. We found promising results with citicoline in patients with BD and cocaine dependence. In recent years the use of amphetamine and methamphetamine has become an important public health concern. However, virtually no research has been conducted on the treatment of amphetamine abuse. We propose a double-blind placebo controlled prospective trial of citicoline in a group of 60 depressed outpatients with bipolar disorder, depressed phase or major depressive disorder and amphetamine abuse/dependence, to explore the safety and tolerability of citicoline, and its efficacy for mood symptoms, stimulant use and craving and its impact on cognition. Our goal is to determine which symptoms (e.g. mood, cognition, substance use) citicoline appears to be most effective and estimate effect sizes for future work.
