ketamine, an anesthetic in human and veterinary use has been proven to relieve major depression subjects in less than an hour. The effects of a single intravenous dose was too small long-term improvement in the mood for an average of three days of benefits remaining for about a week and depression do not return to open for about two weeks.

ketamine fast antidepressant response was examined in both diseases -. Major depression and bipolar disorder in the latest study, published in 2010, researchers at the Maryland National Institute of Mental Health (NIMH), low doses of ketamine in 18 patients with treatment-resistant bipolar disorder. More than half of patients had a reduction in symptoms within 40 minutes, with 13 percent reported an improvement of almost 100 percent. The side effects were mild and of short duration, and include feeling “strange”, a dry mouth and increased blood pressure and heart rate.

Research shows that playing the signal between the neurons in this system, a role gluatamate depression. Ketamine improves the response of other receptors regulate the electrical flow of brain cells helps.

Ketamine is the creation of a medical specialist in the world creates a stir and hope that the results of the study to develop a new class of antidepressants run faster and longer. “These new results show the importance of developing new classes of antidepressants that are not simply variations of existing drugs,” said Dr. Elias Zerhouni, director of the National Institutes of Health.
