Medical Literature

For the past 20 years, there has been a steadily growing body of scientific research detailing the efficacy of ketamine in treating a variety of medical problems. A sampling of literature related to the conditions where ketamine has been shown to be of benefit follows below:

Dosage & Timing of Maintenance Infusions

As with most other drugs, there is a dose: response relationship with ketamine. That is why the relatively low doses that Spravato (the nasal form of ketamine) administration delivers require re-administration once a week at the least, and for many patients twice a week. That is also why the low doses of ketamine administered in clinics that are not staffed by anesthesiologists result in some patients being labeled as “non-responders,” when in fact they would get relief if only a higher dose infusion of ketamine was given.

The higher doses we routinely administer – some even up to 4 or 5 times higher and inducing a light general anesthetic – allow every patient who might respond favorably a chance to do so. That is also why our higher dosing allows longer periods of time to elapse between maintenance treatments, saving patients both money and disruptions in their lives.

Depression

Over the past twenty years, ketamine infusions have been extensively studied for the treatment of medication-resistant depression. Psychiatrists have performed the vast majority of studies, so only very low doses of ketamine have typically been used (0.5 mg/kg given over 40 – 60 minutes). Even at these low doses, we can expect approximately 60 – 70% of patients to find relief. However, within 3 weeks of completing the initial course of 6 low-dose infusions, half to three-fourths of patients have return of their depression.

Fortunately, anesthesiologists can administer much higher doses of ketamine (as much as 4 – 5 times higher), and some patients who do not respond at the lower dose will, fortunately, find relief with a more aggressive dosing regimen. In addition, the higher doses that we give allow a considerably longer period of relief, and patients can thereby extend the time period between “maintenance” infusions. This benefits patient both financially as well as being far less disruptive to their lives.

Suicide

A unique property of ketamine is its ability to dramatically reduce suicidal ideation in many patients after only a single treatment.

Post-Traumatic Stress Disorder (PTSD)

Ketamine infusions have emerged as a third treatment option (along with anti-depressants and cognitive behavioral therapy) for patients suffering from PTSD. Reduction of PTSD symptoms occurs along with a decrease in depressive symptoms. It is believed that by acting as an NMDA antagonist ketamine is able to favorably alter the neuroplasticity of brain synapses.

Obsessive Compulsive Disorder(OCD)

A single dose of ketamine has a beneficial effect on OCD that lasts up to one week. As with other conditions, there is a dose: response relationship, with higher doses of ketamine being more effective than lower doses.

Opioids

Anesthesiologists have used the analgesic effects of ketamine in anesthetized patients since its introduction in the US in 1970. Postoperative patients typically consume around 25% fewer narcotics in the first 24 hours after surgery if given ketamine while asleep in the OR. With our current opioid crisis, it appears that ketamine can play a significant role in reducing opioid consumption in chronic pain patients. Most pain patients who experience at least some relief with ketamine infusions are able to decrease their dependence on narcotics, some to a dramatic degree. Ketamine has also found use in ultra-rapid detoxifying of opioid-dependent patients.

Headache

It appears that glutamate receptors are involved in patients suffering from migraine headaches, and one mechanism by which ketamine works is by targeting these receptors. Ketamine also exerts its beneficial effects on patients with migraine headaches by targeting NMDA receptors.

CRPS

CRPS is recognized as one of the most difficult to treat of all pain conditions due to its having a centralized mechanism. In the lay press, it has been labeled the “suicide pain”, as it sometimes leads patients to take their own lives to escape the pain. Ketamine is usually effective in at least reducing the pain of most patients with CRPS, allowing many to resume a normal life. In treating CRPS, the high doses of ketamine that only anesthesiologists can safely administer are needed to effect relief. In addition, given the overall difficulty in obtaining relief, many times prolonged infusions are required, as well.

Neuropathic Pain

Neuropathic pain, like CRPS, is usually difficult to treat. However, ketamine has shown to be effective in many patients suffering from this type of pain. Higher total infused dose along with the increased duration of infusions are associated with greater pain relief. Like with CRPS, patient expectations should focus on the reduction of pain as opposed to total abolition of pain.

Fibromyalgia

Recent studies indicate that ketamine infusions may be of benefit in treating patients with fibromyalgia.

Ketamine Assisted Psychotherapy

Psychotherapy offered in our KAP options is intended to complement the ketamine infusion therapy process and is not a supplement for a long-term psychotherapeutic relationship. We encourage all our patients to continue pre-existing counseling and psychiatric relationships and we seek to coordinate care with our patients’ therapists and psychiatrists.
