Depressive disorders may be severe, chronic and often life-threatening illnesses. Impairment in physical and social functioning resulting from depression can be just as severe as other chronic medical illnesses. Recent preclinical and clinical studies suggest that the glutamatergic system is involved in the mechanism of action of antidepressants. This study examines whether ketamine can cause a rapid-next day antidepressant effect in patients with Major Depressive Disorder. This study was designed to address the questions: Does the NMDA antagonist ketamine produce rapid antidepressant effects in patients with treatment-resistant major depression? What are the neurobiological correlates of antidepressant response (examining multi-modal MRI, MEG, polysomnography and serum markers) Patients, ages 18 to 65 years with treatment-resistant major (unipolar) depression will in a double-blind crossover study receive either intravenous ketamine or saline solution.
To compare the antidepressant efficacy and safety of DVS-233 SR versus placebo in adult outpatients with MDD.
This study compares the effectiveness of the combination of antidepressants: Lexapro and Pramipexole, with the effectiveness of each antidepressant alone. Purpose: Patients between 18 and 65 years of age with Major Depressive Disorder without psychotic features may be eligible for this 9-week study. Candidates must currently be in a major depressive episode of at least 4 weeks' duration, have failed to respond to treatment with an SSRI (Prozac, Zoloft, Paxil, Luvox, Celexa), and not have failed to respond to more than four antidepressants for the current episode. Candidates are screened with a physical examination, psychiatric evaluation, blood tests, review of vital signs, height and weight measurements, electrocardiogram (ECG), urine test for illegal drugs, and pregnancy test for women. Participants are tapered off antidepressants or other medications prohibited during the study and remain drug-free for 1 week before starting treatment. They are then randomly assigned to take pramipexole and escitalopram, pramipexole alone, or escitalopram alone for 6 weeks. During the study, participants come to the clinic eight times for health assessments and symptoms assessments, which include a check of vital signs and rating scales for depression and anxiety, adverse events, and sexual functioning. Blood and urine samples are collected periodically to monitor health, detect pregnancy in women, and detect illicit drug use. At the end of the 6-week treatment period, participants have a physical examination, ECG, blood test, and check of vital signs. Short-term anti-depressant treatment is offered, and plans are made for long-term treatment. Atendemos pacientes de habla hispana.
