2-Minute Neuroscience: Ketamine

Ketamine is an anesthetic, analgesic, antidepressant, and recreationally used drug. In this video, I discuss hypotheses about how ketamine produces its effects.
TRANSCRIPT:
Ketamine was initially developed as an anesthetic, but today it is also used as an analgesic and an antidepressant. It has been used as a recreational drug since the 1970s.
After administration, ketamine is rapidly and extensively metabolized into an active metabolite called norketamine, which is thought to play an important role in ketamine’s anesthetic and analgesic effects. Ketamine and norketamine both act at a receptor for the neurotransmitter glutamate called the NMDA receptor. Glutamate is the primary excitatory neurotransmitter in the brain, and ketamine and norketamine act as antagonists at the NMDA receptor, which means that they block the receptor and inhibit activity there. Inhibition of NMDA receptors can substantially affect neurotransmission, and is thought to be critical to the anesthetic and analgesic effects of ketamine.
While most other antidepressants take several weeks to achieve a therapeutic effect, ketamine can begin to improve depressive symptoms within hours and last for up to 2 weeks after a single administration. The mechanisms underlying ketamine’s antidepressant action are not fully understood, but it’s thought that it cannot be explained by NMDA antagonism alone. One hypothesis is that another glutamate receptor known as an AMPA receptor may play a key role. AMPA receptors may be stimulated indirectly by ketamine or directly by other ketamine metabolites such as hydroxynorketamine. Stimulation of AMPA receptors may lead to the activation of multiple signaling pathways.
and downstream effects such as new synapse formation in areas of the brain like the prefrontal cortex and hippocampus. These synaptic connections may bolster neural circuits involved with regulating stress and mood. Ketamine also acts on a number of other receptors, however, and there is still much more to learn about ketamine’s antidepressant mechanism of action. Additionally, more evidence about the safety and effectiveness of ketamine needs to be collected for more physicians to support the use of ketamine as an antidepressant.

I work at the Seattle Neuropsychiatric Treatment Center as a ketamine and transcranial magnetic stimulation clinician. I’ve fairly new, but already I’ve seen the light brought back into my depressed and suicidal patients- within one month. It is so hopeful what is to come down the road (fairly soon) with neuroscience and psychiatry. I hope that we can gravitate away from the “one size fits all” depression med dx approach. Thank you for this video! ☺️

[@moneymule8209]

I get that ketamine seems great rn but surely something that was developed to tranquilise horses isn't going to be the optimal therapy for depression. Couldn't scientists tweak it slightly so that it has even more positives for humans instead of using something that was made decades ago for another purpose?

[@kimmybrandt]

@@moneymule8209 Well people usually think of it as a horse tranquilizer for whatever reason- but it was actually first synthesized and used as a human anesthetic (and still is today one of the top human anesthetics). Sure it wasn't initially developed for depression but I don't think that matters much at all; tons of drugs/medications we commonly use were initially developed for a totally different reason. Also I'm no expert, but it would make sense to me that the way it's able to alleviate depression, is because of the disassociative affect itsself- or the mechanism in the brain that causes that.

[@TT-ww8vv]

@@moneymule8209 What the hell does it matter if it's incidentally used in veterinary medicine, if it freaking works? The dosage makes the poison, and someone who is suicidally depressed and teetering on a crisis that might end with them getting shot by the cops doesn't give a shit if it works. Depression can be a terminal illness that is so serious it causes morbidity and mortality in proxies who aren't pathologically afflicted with it. Like the 18th century German existentialist philosopher Arthur Schopenhauer said: "When the terrors of life come to outweigh the terrors of death a man will put an end to his life" and "he who is without hope is also without fear" so what is the hold up in getting this shit out there to all those demoralized people who are about to devastate their friends and family? How many tragedies (and atrocities) might never happen because this stuff works so well and so fast at bringing people back from the brink of nihilistic oblivion that it's practically the Epi-pen of psychiatry? The drug is unique because it basically does the same thing to every mammal brain, and it's as safe to use on premature human babies as it is for foals and kittens. You can use it for general anesthesia without having to intubate and ventilate which makes it pretty much the only thing you can use on badly injured patients in a warzone or disaster area that might have no electrical grid. PCP (phencyclidine) is the devil's NMDA glutamate antagonist that you're likely thinking of when people speak incredulously of horse tranquilizers curing depression. It was formerly used for veterinary reasons because they quickly discovered it made humans dangerously psychotic after surgery. Ketamine causes dissociation, but NO one in a "K-hole" gets off their ass and BANZAI charges the cops, butt naked, and shrugging off pepper spray, beanbags, batons, dogs, tasers, and bullets until they make the news. You dont feel any pain, and it causes feelings of hyperthermia that result in clothes falling off. It's so bad it's used to model schizophrenia. I wish that was just DARE propaganda but it's unfortunately TRUE! Look up the case of the rapper Big Lurch who got "dusted" and killed and ate his girlfriend.

I have been struggling with anxiety and depression for years. Taking SSRI for more than 10 years now and going the same amount of time to psychotherapy. There were some changes throughout the years but some things would not make move at all. I dunno it might not be the reason but it’s very suspicious that after taking ketamin two times I have been able to make significant progress in my life struggles thanks to reduction of anxiety.

How is it possible that ketamine inhibits neurotransmission (by blocking NMDAR activity), but also enhances synaptic plasticity? I read something about ketamine mainly acting on inhibitory interneurons, thereby lifting the inhibition and increasing neurotransmission... But is it possible that ketamine has such specificity?

[@neurochallenged]

It's not fully understood, but what you mentioned is thought to be one way: NMDA receptors are found on GABAergic neurons, so blocking those receptors can lead to a decrease in inhibition and an increase in downstream glutamate release. Also, ketamine metabolites like hydroxynorketamine are thought to be able to directly activate AMPA receptors. Downstream of AMPA receptor activation, mechanisms like increased BDNF synthesis might be associated with new synapse formation, etc.

[@sergiolazaromartinez491]

@@neurochallenged oh wow! I would have thought that ketamine, if something, would also inactivate AMPAR. Still, I am not sure if I am buying that sort of GABAergic specificity... Maybe it's a matter of NMDAR density in the synapses... Anyways, thank you very much for the reply! And thank you so much for all your work as well, your videos are a very nice starting point every time I have to study something new 🙌🏻🙌🏻🙌🏻

There are other indications that GABAergic neurons might be especially sensitive to NMDA antagonism (see pubmed.ncbi.nlm.nih.gov/1835799/), but I agree it's all still very uncertain. And thanks, I'm glad my videos have been helpful! 👍

[@jonathondoherty4384]

It’s unfortunate that the discussion about ketamines effects are limited to the role of glutamate. What’s left out of this discussion is the relationship between glutamate and dopamine in the mesocorticolombic pathway. Ketamine causes a high because of this relationship. If getting the patient high makes ketamine an ‘antidepressant’ then every other substance that causes a high via dopaminergic increase in the Mesolimbic pathway (I.e. all drugs of abuse including cocaine and meth) is an “antidepressant.” This supposed innovation in mental health treatment is very likely to do much more harm than good in the long run.

[@NoNumbersAtTheEnding]

I think you don’t understand how ketamine as an antidepressant is prescribed. Ketamine isn’t taken every day. It is administered ONCE every three weeks and the patient is only allowed to go home once they’ve sobered up. The antidepressant effects occur AFTER the high has worn off and are much more closely associated with decreased neuroinflammtion through some sort of AMPAergic mechanism. You seem to be under the impression that people would just be waking up and taking ketamine pills to start their day. This would not be reasonable, ketamine is a dissociative and prevents competent sober functioning far more than most drugs, even other hallucinogens

[@JennAyBaybAyy]

For two weeks I haven't had a depressive mood, and I feel that my mood and energy are better day by day. I just hope it gets better. When it comes to cost, it is also incomparably low to ketamine drips.
