Ketamine Side Effects: Risks and Management

Yes, while not physically addictive, ketamine can cause a substance use Sober living house disorder. In some cases, treatment may be required or leave people with permanent damage. Long term uncontrolled use is also problematic because it creates a tolerance, requiring higher and higher doses to feel the effects. Some routes of administration, like oral or nasal ketamine, have more frequent dosing schedules, like several times per week over six weeks. Ketamine (sometimes) offers relief from symptoms of depression and, in some cases, puts depression into complete remission.

The dissociative experience may help patients gain new perspectives on their problems and process difficult emotions, particularly when guided by a licensed clinician. KAP is an emerging therapy, and further research is needed to determine exactly how effective it is in treating various conditions. It’s important to remember that it is generally considered only after traditional treatments have failed, rather than as a first-line therapy.

Ketamine: Uses, Effects, Interactions, and Addiction

• The Controlled Substance Act classifies ketamine as a Schedule III non-narcotic drug.
• It remains unclear whether the altered connectivity patterns found in this study could be a direct result of ketamine.
• While ketamine is not traditionally considered highly addictive, users may develop a compulsion to seek out the drug for its psychoactive effects.
• The duration depends on many factors, including the dosage, method of administration, and individual response.
• Those with a history of trauma may be more likely to misuse the drug as its dissociative qualities can help them “escape” from difficult feelings and memories.
• Think of it as the ketamine helping to make new catcher’s mitts for the glutamate, so that the nerve cells can respond to it again.

Five studies were based on the same sample (Liao et al., 2010, 2011, 2012, 2016, 2018). The included studies described structural gray matter and white matter differences, differences in brain functionality and differences in neurotransmitter receptor binding. All retrieved studies were retrospective cohort studies, level IV on the Sackett scale or level 2b on the Oxford CEBM levels of evidence scale (Sackett, 1989; Howick et al., 2018). A retrospective study examined the adverse events of patients receiving long-term oral ketamine for both PTSD and treatment-resistant depression in an outpatient setting.19 A total of 37 patients were examined in the study. The patients received an initial sublingual dose of 0.5 mg/kg, which was held under the tongue for 2–3 minutes to evaluate for any adverse effects. The dosage was begun at 0.5 mg/kg and then titrated up to 20–50% at each of the following treatments.

Finally, we found our complete dataset consisting of 16 studies (see Figure 1) for the inclusion flowchart. ketamine addiction All key articles had to be retrieved by the systematic search strategy. The search concept combination can be displayed as ketamine AND (chronic OR long term OR abuse OR dependence OR known long term use effects OR induced adverse effects). You can also ask about how they monitor patients to reduce the chances of adverse effects, their typical dosage schedule, and steps they take to reduce the risk of addiction and abuse.

Other drugs may affect ketamine, including prescription and over-the-counter medicines, vitamins, and herbal products. Hemodynamic instability Temporary increases in blood pressure, heart rate, and cardiac index may be observed during administration. Vital signs and cardiac function should be monitored during administration. Ketamine is FDA-approved as a general anesthetic to be used as the sole anesthetic agent for diagnostic and surgical procedures that do not require skeletal muscle relaxation. It is also used to induce anesthesia prior to the administration of other general anesthetic agents and as a supplement to other anesthetic agents.

• FA in the left and right frontal white matter was negatively correlated with the total lifetime consumption of ketamine.
• It would stand to reason that the manufacturer would have an enormous incentive to identify and get FDA approval for other indications.
• As noted, there exists some hesitation for its use based on the fact that it may cause transient dissociation; however, more recent studies suggest that this may not be as frequent as previously thought.

The use of ketamine is extending now beyond the field of anesthesia into pain, palliative care, intensive care, and procedural sedation. Many studies have investigated only a single infusion or other short-term use of ketamine. As a result, providers may recommend repeated infusions, but more research is needed to understand the effectiveness and optimal dosage and frequency of ketamine over a longer period of time. If you’re experiencing mental health challenges, consider reaching out to a qualified healthcare provider or licensed mental health therapist.

It is frequently abused in combination with other substances, such as cocaine, MDMA or amphetamines. This agent is a lipid soluble compound, has an initial rapid distribution and large volume of distribution, with a half-life of 10 to 15 minutes. Secondarily, the drug distributes into peripheral tissues with a slower elimination half-life of up to 3 hours, undergoes hepatic metabolism and is excreted in the urine. Oral ketamine is more likely to last for several hours when eaten, and sublingual ketamine can also have a long duration.

Ketamine had few strain-specific short-term effects

When used for anesthesia, ketamine is given as an intravenous injection (IV) or as an intramuscular injection (IM). Some studies suggest the drug may have other medical uses, but more research is necessary to prove its safety and effectiveness in these areas. Research has found that ketamine can quickly relieve depression in people who do not respond well to other treatment.

• In rats, different 5–7-days dosing regimens of ketamine yielded opposite effects on cognitive tasks in which the rats had to detect novel objects, or novel placement of objects.
• The duration of these effects depends on the method of administration, typically lasting between 30 minutes to 3 hours.
• Therefore, the different functional connectivity patterns could in part be caused or influenced by the direct, short term effects of ketamine.
• For many people, ketamine therapy will be an ongoing and lengthy process.

Earlier studies reported that other ketamine metabolites, including 2S,6S-HNK and (R,S)-norketamine (NK), can activate signaling pathways, such as mTOR, thought to underlie ketamine’s effects in prefrontal cortex (Paul et al., 2014). The potency of HNK and NK for activating mTOR in PC12 cells paralleled the effectiveness of these metabolites as antagonists at α7 neuronal nicotinic receptors (Moaddel et al., 2013), possibly implicating nicotinic receptors as important antidepressant triggers. However, dehydronorketamine is also a potent α7 nicotinic antagonist (Moaddel et al., 2013), but subsequent studies indicated that dehydronorketamine lacks antidepressant-like effects in rodents (Salat et al., 2015). Thus, the evidence for nicotinic receptor involvement remains equivocal. At a minimum, this set of studies raises important questions about the role of NMDAR inhibition in triggering the antidepressant actions of ketamine.
