Everyone is trying to be not to
optimistic, but absolutely nothing has ever actually cured the disease of
depression. This is obviously a massive
improvement.
It works by reacting with the
glutamate receptors which represent half of the receptors. That it works immediately and that side
effects appear to be resolvable is also great news.
It also informs us of the
principal causation route for depression however driven. Simple exhaustion brings on low level non
clinical symptoms that often interfere with decision making. Perhaps a low dose can be designed to provide
relief for the early onset of such symptoms.
It also is bound to be integral
to the treatment of all forms of drug abuse which is often driven by
depression. Alcoholism is most
noteworthy, but it is surely true for the rest.
It would be nice to have a safe
treatment that allows most substance abuse to be resolved.
I think we can be optimistic.
Club drug ketamine cures depression instantly: How?

(CBS) What's the latest recreational drug to make its way to the
medical field? Ketamine, also known as "Special K." The club drug,
typically used by veterinarians as a cat tranquilizer, is said to provide patients
an "instant" relief from depression, according to a new study.
Doctors at Ben Taub General Hospital
in Houston are
now experimentally using the drug to treat some patients who come to the
emergency room with suicidal depression,NPR reported.
Is there an antidepressant shortage we don't know about?
Dr. Anu Matorin, medical director of the Psychiatric Emergency Center
at the hospital, told NPR that antidepressants may help suicidal patients
eventually, but often take weeks or months to kick in. During the critical few
days when very depressed patients have suicidal thoughts, they may be a threat
to themselves or to others and are sometimes admitted to inpatient units.
That's why researchers at Ben Taub are among a growing number of
scientists trying to transform psychiatric care - with the help of the club
drug. Previous research suggests the anesthetic ketamine could help treat
depression almost instantly. Dr. Sanjay Matthew, associate professor of
psychiatry at Baylor College of Medicine leads the ketamine research
program at Ben Taub General Hospital .
"The focus is on really rapidly helping someone get out of a depressive
episode," Matthew told NPR.
"We can take care of a migraine in hours," added Dr. Carlos
Zarate, a ketamine researcher at the National Institute of Mental Health.
"So why do we have to wait weeks or months with depression?"
This isn't the first report of ketamine helping people with depression.
A 2006
study of Zarate's found a single intravenous dose of ketamine helped
relieve treatment-resistant depression symptoms within 2 hours.
How does ketamine help depressed patients?
Those who take the drug typically say, "'I feel that something's
lifted or feel that I've never been depressed in my life. I feel I can work. I
feel I can contribute to society.'" Zarate told NPR. "And it was a
different experience from feeling high. This was feeling that something has
been removed."
Ketamine works differently than other antidepressants. While pills like
Prozac boost the levels of the neurotransmitter serotonin to make people feel
less depressed over a period of time, an injection of ketamine works on an
entirely different neurotransmitter, glutamate. It blocks the receptors
critical for receiving glutamate's signals which quickly improves the brain
cell's electrical flow. That in turn reduces depression, according to the
NIMH.
Dr. Asim Shah, who directs the mood disorder program at Ben Taub
General Hospital, told ABC
News the researchers hope the effect lasts.
"Will it cure depression for a year or longer? I don't think
so," Shah said. "But we're hoping it will work for a few months"
But that doesn't mean people should self-medicate with the illegal
drug. Ketamine is popular and "dance clubs and raves," and can be
injected, consumed in drinks, or added to smokeable materials, according to the
U.S. Drug
Enforcement Administration. Some users fall into a dissociative
"trip" on the drug, which is called a "K-hole."
Dr. Robert Glatter, emergency medicine physician at Lenox Hill Hospital
in New York City, said the drug has similar effects to PCP, and may cause
visual hallucinations, vivid dreams, confusion and disorientation, increased
salivation, and problems with heart rhythm and breathing. Besides animals, the
drug is sometimes administred to people along with a sedative in the hospital
for patients undergoing painful procedures.
