Ketamine: a factory reset for the brain

Posted by FredPotter on February 19, 2007, at 22:12:59

Interesting article on the use of Ketamine in treating depression in one of the January issues of New Scientist. I'll try to get a copy and paste it. It's apparently a nightmarish experience if you go into a K-hole but then you're up and running again.

Interesting that people used to say that the blissful Near Death Experiences (NDEs) experienced by many was just the same as Ketamine. Obviously not, although the after effects sound similar.

Must pop in the vet on the way home and get her to inject me with some (joke)

Dmt is what you're thinking of as the near death experiance drug. Various forms of DMT is in a legal grey area of "research chemicals". Its the most powerful hallucengenic known to man so if you really wanted to reboot your brain thats probably the way to go.

Cant find the article, only reference to it but it also prevents ketamine induced neurotoxicity.

Australia seems to be way ahead of the pack on this. They've been using ketamine drips to treat a variety of neurological conditions, including some kinds of chronic pain (like the one I've got). I would accept in an instant, if it was offered to me. My pain doctor looked at me askance when I mentioned it.

That was valuable info on Lamotrigine Rovers95. Lar - The New Scientist article talks about a severe pain condition whose name I forget. Everything hurts apparently. And K works like magic. I don't live in Oz and here in New Zealand "askance" doesn't begin to describe how my doc would look at me if I said, "Ketamine". He's probably never heard of it anyway. What's this DMT? I thought LSD still topped the psychotropic charts

Benzodiazepines are the most robust way to prevent NMDA antagonist neurotoxicity, although curiously LSD has been shown effective in animals for this purpose.

I never found a K-hole to be "nightmarish"; it wasn't exactly FUN, but it was metaphysically profound. It didn't really help my depression, though. Ketamine is something you'd want to stay away from using chronically, IMHO, though for pain I'd imagine it can be very effective. NMDA antagonists attenuate tolerance to opioids. Ever seen video footage of dissociative abusers? They often can't count down from 100 ... Although John Lilly was quite functional--albeit nutty--and he used high-dose ketamine for 100 days straight.

Recommending the use of DMT to anyone is irresponsible; the likelihood of lasting psychological trauma is much higher than with ketamine. The analogs on the gray market (such as 5-methoxy-DMT) do not have the same effect, although they can be quite potent.

Their not, sodium - voltage inhibitors (like lamictal!!) are, lost the study but it tells their is no pharmagenic reaction between the benzo n ket tho it makes u more relaxed i.e. less prone to anxiety!!!

Well, I really should've said "barbiturates" instead of "benzodiazepines". That is my mistake. Please find evidence that barbiturates have been shown ineffective in blocking NMDA-induced neurotoxicity. Yes, Na+ blockers are effective, but I don't like the idea of mixing and matching drugs like this. The reason I mention the benzodiazepines and barbiturates in this context is because they have been USED CLINICALLY with ketamine for years.

Benzodiazepines are also effective enough, IMHO, to be used by people using sane (read: not animal study) doses of ketamine. I'm not positive about this, but I don't think there's any evidence that this neurotoxicity even occurs in humans, though I've seen enough of the effects of dissociative abuse to suspect otherwise. Note that these people were using doses well in excess of what anyone should.

Most people would be well-advised to stay away from drugs like ketamine and MK-801. PCP is the most dangerous, but for different reasons. Memantine is much safer.

I definetly would not reccomend someone who was inexperianced with the subject matter to try any psychedelic especially DMT. Its more potent natural forms are in even less of a grey legal area compared to the RCs. But i certainly dont reccomend anyone trip on ayahuasca.

Its been used in various forms by tribal cultures for religious reasons since we walked upright. While lsd is strong a trip on DMT usually involves leaving your body for 4+ hours and being completely unaware of your surroundings and experiancing other places/worlds/beings. Extremely potent and would be extremely scary for someone inexperianced with drugs of this nature.

I only used Special K recreationally a few times but it made me feel like I was going to die; indeed, that I was dying.

Nothing like some good old Ecstasy for depression, I say! [Note: I am just kidding. Ecstasy probably contributed to the worsening of my depression, actually.]

Is this the article?
http://www.ketamine.com/antidepressant-potential.html

> Everything hurts apparently. And K works like magic.

Yes, RSD. Also known as complex regional pain syndrome. I've been diagnosed with that recently. They're injecting anaesthetic around my spinal canal Thursday. As I said, I'd go for the ketamine in a flash.

> I don't live in Oz and here in New Zealand "askance" doesn't begin to describe how my doc would look at me if I said, "Ketamine".

I hear ya. All they think of is drug-seeking.

Dimethyl-tryptamine, if I recall correctly. There is a whole body of research into tryptamines and related molecules (a book called PIHKAL, for example). If you've got a background in organic chemistry, they're fairly easy to play around with. Everything you'd ever want to know is probably in Erowid:

Interesting, I would often fall into what I called lithium holes. Although, it is probably a totally different mechanism, and I cannot compare that to what a K-hole feels like.

The study described in that New Scientist article was different in one substantive way from the Australian work, and that done in Philadelphia. Instead of one single dose, patients were on a 24/7 i.v. drip, for five to seven days straight. Some were even comatose. Coming out of that, roughly one third had long-term remissions (greater than six months). About half went on to have a second treatment, and two subjects had a third. But, a significant number became pain free. About half, if I recall correctly.

A remarkable outcome, IMHO. There is nothing like it, in the literature.

I hold my NDE in reserve, for a later date. ;-)

In doses of 2mg/kg or less, MDMA is perfectly safe to use once per month--and this is conservative. Of course, YMMV, but IMHO most worsening of depression due to MDMA use is due to the inability of the subject to integrate such a positive experience into the ego when ordinary life has a dearth of such "peak" experiences.

I onced asked a pharmacology professor of mine about neuroprotection for use of MDMA. He said, "Why are you worried?"

For an explanation of this, check out the work of Olney, et. al. on NMDA antagonist neurotoxicity.

You seem to have a broad knowledge of this subject (I can't recall the details so clearly), but isn't it true that Olney's lesions were only ever found in animals? No human autopsies, right?

It's impossible to know for sure what drug was involved (I was high on the pipeline from a consistent source, though), but I used PCP daily for about a year. I honestly attribute zero lasting effects to that teenage period of.... whatever I was thinking.

If I remember correctly, low doses of NDMA antagonists can greatly facilite neuronal placiticity, wherase high doses can cause toxicity?

I remember reading a number of places that NDMA antagonism can prevent the stress (or glutamate) induced reduction of hippocampal granual layer proliferation. (or something)


So is it possable that a "theraputic dose" of ketamine might not be so toxic?

>Just wondering what are barbituates???

You've never heard of barbs? They're non-selective CNS depressants - dry alcohol is a poor analogy that is often used. Extremely popular as sleeping pills and tranquillizers from 1903 when Veronal (barbital) was first marketed, until the early sixties when benzos hit the market. They are also very addictive and very dangerous in overdose. Apparently tolerance to the therapeutic effects develop quickly but tolerance to the respiratory depressant effect does not. What you end up with after maybe a few months or years of daily use are addicts who have to take a dose close to that which causes respiratory failure just to achieve an effective therapeutic response.

It was notoriously easy for the addict in this situation to wake and forget they'd taken their nightly dose and take another from the bottle on their bedside table. Many never woke again. This is what happened to Judy Garland with Seconal (secobarbital) and Marylin Monroe (though Marylin is said to have taken a deliberate overdose of Nembutal [pentobarbital]), and this happened to **many** ordinary men and women (but mostly women) of that era. That's why the benzos with their almost ridiculous LD50 became so popular. Benzos are also more effective anxiolytics.
