What is ketamine used for medically?


It’s been well-documented that ketamine’s first use was for anesthesia. Since it was synthesized, the medicine has also been used as a powerful sedative in non-surgical settings. In fact, The United States Defense Health Board says that morphine is losing its status as the preferred anesthetic in “Tactical Combat Casualty Care pain management” and advises ketamine as a new option to battlefield analgesia.


“Ketamine has been widely used to provide analgesia in burn dressing changes, during excision and grafting, and for sedation. It has a major role in repeated anesthetics for burns dressings. The major advantage of ketamine in burns is that unlike other agents, it usually preserves airway and spontaneous respiratory function in addition to providing good sedoanalgesia.”

Acute Pain Management

Many doctors have started recommending ketamine for this purpose. Acute pain is a type of pain that is localized, has a specific cause, and goes away relatively quickly on its own as your body heals. But in some cases, particularly after surgery, you may need help managing acute pain.

Opioids are often the go-to choice for acute postoperative pain. “Unfortunately, possible hyperalgesia from opioids can result in increased analgesic requirements. Ketamine, however, can block these mechanisms; when administered at sub-anesthetic and repeated doses, ketamine has been shown to prevent the development of increased pain sensitivity and opioid tolerance.”

Chronic Pain Management

“While acute pain is a normal sensation triggered in the nervous system to alert you to possible injury and the need to take care of yourself, chronic pain is different. Chronic pain persists. Pain signals keep firing in the nervous system for weeks, months, even years.”

The odd thing about chronic pain, of course, is you do not necessarily remember when it began or what caused it. You may have had hip replacement surgery a decade ago, but even though your doctor says nothing is physically wrong, the pain continues. Or you may have realized that you have lower back pain, even though you’ve never had an injury or illness that would contribute to such pain.

In this case, a doctor may recommend ketamine to reduce the symptoms and discomfort in the affected area of your body. Ketamine may be prescribed to help manage chronic pain which could be caused by several conditions, including:

  • Sprained muscles
  • Broken bones
  • A back injury
  • Injury following a surgical procedure
  • Arthritis
  • An ear infection
  • Cancer
  • Neurogenic pain, or pain caused by nerve damage
  • Psychogenic pain (pain not caused by previous injury or disease or any apparent sign of harm outside or inside the nervous system)

Ketamine for adolescents?

The U.S. Centers for Disease Control and Prevention reports that more than three million adolescents between 12- and 17-years old experience symptoms of depression every year. In a 2019 study by Pew Research Center, 70 percent of teenagers called depression and anxiety a “major problem” for “them and their peers.”

Ketamine has been used successfully to treat teenagers suffering from depression since the medicine was approved in 2019. A report by the U.S. National Institutes of Health was cautiously optimistic for its use with teenagers: “Ketamine was shown in youth to generally improve depressive symptoms, decrease acute suicidality, and reduce mood lability, though a number of subjects remained resistant to its treatment. These findings substantiate the need for further longitudinal studies investigating ketamine’s long-term safety, its efficacy, and abuse potential in the youth.”

A doctor specializing in pediatric psychiatry is best capable of assessing your child’s condition and treatment options.

Final thoughts

Ketamine has a number of uses beyond its original intent for anesthesia, including managing symptoms of treatment-resistant depression, anxiety, PTSD, and other mental health and chronic pain conditions.

An innovative new treatment option, ketamine started as a fast-acting anesthetic and pain reliever. Research in the last two decades has shown that ketamine is a powerful new tool for the treatment of mental health and mood disorders or pain conditions.

Ketamine works to stimulate the growth and regrowth of neurotransmitters in the brain, essentially rewriting the parts of the brain causing distress. Up to 70% of patients may be able to find relief from the symptoms of depression after a series of IV ketamine infusions.

Do Ketamine Infusions Help Depression?

Mood disorders like anxiety and stress are prevalent, with the U.S. Census Bureau finding a third of Americans are showing signs of depression. The good news is ketamine infusion therapy may help control symptoms of depression or anxiety.


Not all medicine needs to be dispensed orally. Instead, some doctors will administer medications like ketamine by injecting through a patient’s vein intravenously. Years ago, infusion systems could only be used in hospital settings, but now they are also available in standalone clinics and homes administered by specialized nurses or other staff. In newer systems, the ketamine dosage and flow rate are controlled digitally, ensuring you only receive the prescribed amount over a certain time period.


Wrong. That’s one of the great myths about the medicine, that and the one that it’s more known as a club drug than anything else. Don’t kid yourself into believing pop culture myths about ketamine. The drug originated as an anesthetic in 1962 and that’s still its top medicinal use. But ketamine also works as a sedative and is even used to help treat depression when dispensed as a nasal spray or through infusion therapy.


If you watch televised hospital dramas, patients getting treatment intravenously (infusion therapy) is a common sight. But did you ever stop to wonder about the history of the process? Probably not, but that’s ok. Since at least the Middle Ages, mankind had been looking for ways to transfer blood from human to human, mostly to cure or prevent illnesses, oftentimes failing or just being told the attempt was illegal. In the late 17th and early 18th centuries, Sir Christopher Wren made the first successful transfusion machine using a pig’s bladder. The 19th century saw more tweaks to infusion design, and by the mid-20th century, the machines were commonplace in hospitals across the country. But they’re more than just blood transfer devices.


The short answer is yes, most patients who undergo infusion therapy to treat depression experience positive outcomes in a short period of time. But getting to that point is often a long, arduous journey. In fact, COVID-19 has only made it worse. The U.S. Centers for Disease Control and Prevention said that 40 percent of U.S. adults reported mental health issues as of June 2020, coinciding with the pandemic, ruined economy, and social and racial disruptions.
People who are depressed often struggle with symptoms like anger, sadness, fatigue, trouble sleeping, and many others. Women are more likely than men to be depressed, but the illness also affects children and teens. One common storyline in all cases is that mental health disorders can’t be cured, but their symptoms can be treated, often with a combination of psychotherapy and antidepressants or newer therapeutic options like ketamine infusion. But how does ketamine work?


All pain, mental and physical, is controlled by the brain. Though science and medicine have made strides over the last several decades in understanding the relationship between the two, no one knows for certain how to completely regulate the brain’s perception of pain and depression. Understanding the glutamate system is key, as it’s the starting point for the billions of neutrons transmitting information back and forth related to memory, punishment and reward, and moods, for example. When those neurotransmitters are out of whack, trouble starts brewing. Ketamine may strengthen neurotransmitters, thereby soothing common symptoms of depression in the process.


If you’re suffering from depression, you’ll need a diagnosis before treatment begins. First, a medical doctor will give you a physical, inquire about medical history, and run tests that could exclude conditions that could result in depression. Second, or instead of a physical, a therapist will perform a psychological exam focusing on emotions, behavior, and moods. Finally, the outcome of one or both exams is then compared to conditions in the DSM-5 for a formal diagnosis.


Instead of getting help to fight depression, most people do nothing, either out of shame, lack of resources or they don’t recognize there’s a problem. People with mental illness who commit to treatment usually undergo psychotherapy, self-help, take antidepressants, or take medicine. Some try alternatives like ketamine infusion therapy.


If you are suffering from depression, get help, and don’t wait for the symptoms to worsen. Talk with your doctor or mental healthcare professional about therapy or medication best suited to your condition and ask about the health benefits and potential risks of using a newer treatment like ketamine infusion therapy.

What Part Of The Brain Does Ketamine Affect?

The human brain is the most complex organism known to man – containing more than 100 billion neurons – and it’s the pain control center of our lives. If you’re experiencing mental or physical discomfort that persists despite conventional treatment, you may benefit from alternative drugs like ketamine which can offer relief.


Originally synthesized as an anesthetic in 1962, ketamine was approved by the U.S. Food and Drug Administration eight years later for human use. Today, the drug is still called on for anesthesia for patients having minor surgical procedures and as a sedative for irate or agitated persons. Over the last four decades, ketamine has been subjected to much study and debate about its efficacy in treating symptoms of mental illness, including bipolar disorders, depression, anxiety, and posttraumatic stress disorder.


One key to ketamine’s potential therapeutic value in helping the brain manage pain is its effect on the glutamate pathway. Glutamate is an important neurotransmitter in the brain and controls large swaths of our nervous system. If the glutamate receptors are overactive, you could experience long-term depression, but ketamine does its thing by blocking glutamine receptors. The drug also has strong anti-inflammatory properties, which is one of the reasons it may work to reduce chronic inflammation associated with depression.
Ketamine and its therapeutic effect on our brain are subject to much debate. Researchers know that ketamine has been demonstrated to lower some of the symptoms of mental illnesses like anxiety, depression, posttraumatic stress disorder, and physical discomfort associated with chronic pain, but even scientists on the side of caution also advocate more thorough testing thanks to its potential benefits.


Several areas of the human brain may be affected by ketamine, but research has yet to conclude the power the drug has on these compromised regions. Parts of the brain affected by ketamine:

Medial prefrontal cortex

The Medial prefrontal cortex is in the frontal lobe. Chronic pain affects decision-making, self-control, processing risk and fear, how emotions get regulated, and power over amygdala activity. This area controls emotion-driven behaviors. According to the U.S. National Institutes of Health: “Chronic pain is considered to develop as a result of the persistence of pain memory and inability to erase pain memory after injury.”


The Amygdala is situated near the hippocampus, in the temporal lobe’s frontal portion. The brain’s decision-making ability, determining punishment versus rewards, memory, and emotional responses are affected by chronic pain. This region of the brain is important in forming affective disorders.

Periaqueductal gray

The Periaqueductal gray surrounds the cerebral aqueduct in the tegmentum of the midbrain.

Anterior cingulate cortex

This is housed in the cingulate cortex’s frontal area. It’s here our brain works overtime regarding chronic pain, performing most of the heavy lifting. This region has some say in autonomic functions, attention allocation, morality, and ethics, anticipating rewards, controlling impulses, decision-making, emotion, and understanding physical pain.


The Hippocampus is located in the medial temporal lobe. This is where the brain works on the consolidation of memories, spatial orientation, navigation, emotion, and learning. The Hippocampus belongs to the limbic system, with changes in it caused by the brain’s acknowledgment of chronic pain.

Nucleus accumbens

The Nucleus accumbens lives in the basal forebrain. This is where aversion, reward, interpretation of motivation, reinforcement learning, and the brain’s interpretation and reaction to addiction happens. Brain research shows the transition of pain to something more chronic is controlled by the malleability of the nucleus accumbens.


The experts at MedicalNewsToday say that “Ketamine is safe to use in controlled, medical practice. Used outside the approved limits, its adverse mental and physical health effects can be hazardous. Like any form of medication, you need to consult with a medical professional before use.


Though ketamine has been around for almost 60 years, its therapeutic use in calming symptoms of mental illnesses has only been researched for about 20 years. Based on your illness, symptoms, and under optimal conditions, treatments like ketamine can help minimize distress from bipolar disorder, depression, anxiety, and other mental health disorders.
