The NMDA receptor plays a role in how glutamate transmits messages between brain cells. Ketamine also has smaller effects on other receptor subtypes, such as the dopaminergic and opioid receptors. Esketamine is approved by the FDA specifically as an option for treatment-resistant depression and major depressive disorder with suicidal thoughts or actions. Talk with mental health care professional or primary care doctor if you’re interested in trying ketamine for depression, says Yalda Safai, MD, a New York-based psychiatrist at Pasithea Clinics.
Ketamine can do more than a typical antidepressant.
The drug also quickly restored the coordinated activity of prefrontal neural circuits that were disrupted by chronic stress. However, the researchers found that ketamine didn’t work by halting the stress-induced spine loss. Studies in animals have shown that chronic stress also leads to the loss of communication between brain cells (neurons) in the prefrontal cortex area of the brain.
Inducing general anesthesia
- They belonged to the joint family (55%) and the majority had family income below Rs. 5000 (40%).
- At this time, its best used for short-term relief, just long enough to get you through a crisis and into a more holistic program that suits your needs,” Lam says.
- It’s also been cited as a drug of misuse under the moniker “special K.”
Thirty-nine studies looked at ketamine, 10 looked at memantine, nine looked at dextromethorphan, three looked at amantadine, and eight looked at magnesium. Most studies were from Europe, the UK and the USA, and 19% received some form of financial support from pharmaceutical companies. In the earliest studies of depression, ketamine was given intravenously (or directly into the bloodstream). A plastic catheter was inserted into a vein in the arm, and the medicine was infused over a period of about 40 minutes. The “traditional” dose in these studies was based on a patient’s weight and was calculated as 0.5mg of drug per 1 kg of body weight. So a person who weighs 70kg (~154 lbs.) would receive a dose of 35mg.
There was a significant improvement in depression, anxiety, and the severity of illness after 2 weeks and 1 month of the last dose of ketamine. Significant improvement at 1st h of the first dose was seen in depression and anxiety and not for illness severity. There were transient adverse effects observed in some patients which subsided within 1 h. The effect of subanesthetic dose of ketamine was assessed on depressive and anxiety symptoms. Illness severity and improvement were assessed after treatment with ketamine. Conventional pharmacotherapy usually takes several weeks (usually 4–12 weeks) to improve symptoms.
Dr. Brian Johns has a great Psychology Today post to help people decide whether a ketamine clinic offers a reasonable level of quality care. A form of ketamine called esketamine (brand name Spravato) was developed and tested with financial support from Janssen (a subsidiary of Johnson and Johnson). Esketamine received FDA approval for treatment-resistant depression in 2019 and approval for depression with suicidal ideation in 2020. In contrast to ketamine (which is most commonly administered intravenously), esketamine is administered as a nasal spray.
Perpetrators who use it in this manner may slip it into a beverage of the person they wish to victimize. Ketamine makes people feel detached from their environment, eases pain, and produces hallucinations, which has led to its inappropriate use. Evidence shows that ketamine is safe for use in people within a wide age range when taken correctly. General anesthesia denotes a sleep-like state, while dissociative refers to the effect of feeling disconnected.
Ketamine Side Effects: Short-Term and Long-Term
Those lost connections start to regrow within 24 hours of the first dose of medically supervised ketamine, according to research using PET brain scans. The more synapses the patients grow, the better the antidepressant effects of ketamine are for them. Christa Coulter-Scott, 55, started ketamine treatment in a clinic in Gainesville, Georgia, in 2021, where her care was supervised by an on-site nurse practitioner. Coulter-Scott had had depression what is ketamine how it works and may help with severe depression and anxiety since childhood and was diagnosed with PTSD and chronic pain as an adult.
Write one good thing about you every day, even if it’s a little one. Use “sensory resets” like a warm shower, fresh air, or a preferred song to enhance your mood. Tell somebody, “I’m not feeling great today,” so you don’t carry it alone. Untreated depression in older adults can mimic dementia symptoms (“pseudodementia”) and may increase the danger of later cognitive decline.
- Each session follows a structured process to ensure the best possible experience.
- However, some research has suggested that the IV-infused drug provides a faster response than the nasal spray.
- You might think ketamine sounds like the perfect solution for depression, but it’s still not considered a firstline option for most people.
- If you move forward with treatment, then at our next visit, you’ll receive your first dose of SPRAVATO®.
What is ketamine? Understanding the drug after Matthew Perry’s death
As a dissociative anesthetic, the drug may make you feel detached from your thoughts or reality. It may also cause hallucinations, confusion, or a sense of euphoria. It’s well known for being used to induce anesthesia or manage pain. Now, it may also be a valuable treatment option for some people living with treatment-resistant depression.

When someone has depression, there are changes in the brain’s circuitry, including how neurons communicate with one another. Ketamine seems to allow for a regrowth of synapses (connections between neurons), explains John Krystal, MD, chair of the Yale School of Medicine Department of Psychiatry. Manufacturers of the esketamine product, Spravato, note similar side effects, but also state there may be potential for misuse as the product becomes more available for at-home use. Due to its potential for misuse, ketamine is considered a schedule 3 drug on the Drug Enforcement Administration (DEA)’s list of controlled substances.

The neurons lose dendritic spines, the small outgrowths on brain cells that receive signals from neighboring neurons. “Of course, the benefits of ketamine shouldn’t be seen as a magic bullet. At this time, its best used for short-term relief, just long enough to get you through a crisis and into a more holistic program that suits your needs,” Lam says. Before a drug comes to market, it must submit scientific safety data to the FDA for approval. Once that medication has been used clinically for decades, however, alternative uses become widely recognized and accepted.
What About Esketamine?
Both Krystal and Stewart agree that ketamine is addictive, but they say addiction isn’t likely when people receive ketamine under proper supervision by a doctor. Before ketamine, I felt anxiety, PTSD, and depression ruled my life. For 25 years, he’d tried virtually every antidepressant on the market and went to talk therapy. “The depression was just a constant,” says Winograd, 54, who lives in Portland, Oregon. “This is dangerous, as it’s important to be monitored for side effects by a nurse or doctor during the treatment,” she says. You can find freestanding clinics and online services that offer ketamine, but Safai cautions that many of them don’t offer adequate supervision.
Anesthesia
There’s evidence that ketamine can have a very rapid onset of effects in neuroplasticity, says Gerard Sanacora, MD, PhD, director of the Yale Depression Research Center. You’re not alone if you’re living with depression, and especially if treatments have yet to make a big difference or have stopped working as effectively. You might think ketamine sounds like the perfect solution for depression, but it’s still not considered a firstline option for most people. Racemic ketamine, on the other hand, is not currently approved for treating depression. It’s FDA-approved only for use as a short-acting anesthetic in humans and animals.
