The World Health Organizations Expert Committee on Drug Dependence are gathered this week in Geneva to consider ketamine hydrochloride and several other drugs for scheduling under the Convention on Psychotropic Substances, a treaty established in 1971 as an international control system for the manufacture, distribution, transfer and use of drugs. How the WHOs scrutiny of ketamine might impact U.S. supplies - if at all - is unknown. In the United States, organized veterinary medicine has been on high alert for months given ketamines importance to animal health care. Ketamine has played a role in veterinary medicine for half a century as an anesthetic and adjunct to pain control, and it remains a critical drug in equine medicine. Regulators are taking a harder look at ketamine because its popularity as a recreational drug has increased worldwide, with China becoming the epicenter of global ketamine consumption and production, as reported by the BBC and other news media. Right now, the ...
Increasing preclinical and clinical evidence underscores the strong and rapid antidepressant properties of the glutamate-modulating NMDA receptor antagonist ketamine. Targeting the glutamatergic system might thus provide a novel molecular strategy for antidepressant treatment. Since glutamate is the most abundant and major excitatory neurotransmitter in the brain, pathophysiological changes in glutamatergic signaling are likely to affect neurobehavioral plasticity, information processing and large-scale changes in functional brain connectivity underlying certain symptoms of major depressive disorder. Using resting state functional magnetic resonance imaging (rsfMRI), the „dorsal nexus "(DN) was recently identified as a bilateral dorsal medial prefrontal cortex region showing dramatically increased depression-associated functional connectivity with large portions of a cognitive control network (CCN), the default mode network (DMN), and a rostral affective network (AN). Hence, Sheline and ...
Preferred Name: Ketamine Hydrochloride Definition: The hydrochloride salt of a synthetic derivative of cyclohexanone with analgesic and anesthetic activities. Although its mechanism of action is not well understood, ketamine appears to non-competitively block N-methyl-D-aspartate (NMDA) receptors and may interact with opioid mu receptors and sigma receptors, thereby reducing pain perception, inducing sedation, and producing dissociative anesthesia. NCI-GLOSS Definition: A drug used to cause a loss of feeling and awareness and to induce sleep in patients having surgery. It is also being studied in the treatment of nerve pain caused by chemotherapy. Ketalar blocks pathways to the brain that are involved in sensing pain. It is a type of general anesthetic.

AbstractIt has been suggested that ketamine cause injury during developing brain. Minocycline could prevent neuronal cell death through the activation of cell survival signals and the inhibition of apoptotic signals in models of neurodegenerative diseases. Here we investigated the protective effect of minocycline against ketamine-induced injury in neural stem cell(NSC) from neonatal rat. Ketamine (100μM/L) significantly inhibited NSC proliferation, promoted their differentiation into astrocytes and suppressed neuronal differentiation of NSCs. Moreover, the apoptotic level was increased following ketamine exposure. Minocycline pretreatment greatly enhanced cell viability, decreased caspase-3-like activity, even reversed the differentiation changes caused by ketamine. To elucidate a possible mechanism of minocycline neuroprotective effect, we investigated the phosphoinositide3- kinase pathway using LY294002, a specific PI3K inhibitor. Immunoblotting revealed that minocycline enhanced the phosphorylation

Patients in palliative care need rapid-acting pharmacological options for psychological distress. N-methyl-D-aspartate antagonist ketamine is known to have a fast onset of anti-depressant and anxiolytic action. Its S-enantiomer S-ketamine (or esketamine) is an analgesic used as a routine treatment for refractory pain as an intravenous infusion (0.25 mg/kg over 45 min). This study investigates whether S-ketamine pain therapy has a positive impact on psychological distress caused by anxiety and depression in palliative care. Patient routine data from a palliative care unit of a tertiary care hospital were used in a retrospective analysis after positive ethics approval. Eight patients, who received analgesic S-ketamine treatment, were compared to a control group matched by gender and age. The main analysis was conducted using three-way mixed MANOVA followed by two-way mixed ANOVA. Target variables were the values for anxiety and depression in the state-trait anxiety-depression inventory STADI. The

Q. When I broke my leg a few years ago, I needed surgery to reset the bone correctly. The anesthesiologist gave me intravenous ketamine to put me to sleep. As I was recovering from the anesthesia, I experienced an amazing change in my mood, like a cloud lifting from my brain. I have suffered from depression almost all my life. It is cyclical and has not responded to medication for almost 50 years. The antidepressant effect of ketamine seemed to last. I have tracked my depression carefully for

A 2017 series of articles by researcher Chittaranjan Andrade in the Journal of Clinical Psychiatry reviews the last 10 years of research on ketamine, the anesthetic drug that in smaller doses (0.5 mg/kg of body weight) can bring about rapid antidepressant effects. Ketamine is typically delivered intravenously (though it can also be delivered via inhaler, injected under the skin or into muscles, and least effectively by mouth). Ketamine can improve depression in less than an hour, but its effects usually fade within 3 to 5 days. Repeating infusions every few days can extend ketamines efficacy for weeks or months.. Andrade cited a 2016 meta-analysis of nine ketamine studies by T. Kishimoto and colleagues in the journal Psychological Research. The meta-analysis found that compared to placebo, ketamine improved depression beginning 40 minutes after IV administration. Its effects peaked at day 1 and were gone 10-12 days later. Remission rates were better than placebo starting after 80 minutes and ...

... , or ketamine hydrochloride, is a non-barbiturate, rapid-acting dissociative anaesthetic used on animals and humans. It has also been used in human medicine for paediatric burn cases and dentistry, and in experimental psychotherapy. It is being abused by an increasing number of young people as a club drug, and is often distributed at raves and parties.
The induction of mTOR signalling suggests that the ability of ketamine to increase synaptogenesis is mediated by stimulation of this protein synthesis regulatory pathway. To directly test this hypothesis, the influence of rapamycin, a selective inhibitor of mTOR (figure 3), on synaptogenesis was examined. Rapamycin pretreatment completely blocked ketamine-induction of spine number and function of layer V pyramidal neurons in the PFC [42]. In addition, rapamycin pretreatment completely blocked the induction of the synaptic proteins PSD95, GluR1 and synapsin I, resulting from ketamine administration. These findings provide direct evidence that ketamine-induction of synaptogenesis requires mTOR signalling and synaptic protein synthesis.. Next, studies were conducted to determine whether the behavioural actions of ketamine are also dependent on mTOR signalling. Pretreatment with rapamycin completely blocked the antidepressant effects of ketamine in the FST, LH and NSF test [42]. Moreover, the rapid ...
N-methyl- D-aspartate (NMDA) receptors are involved in the development of central sensitization associated with chronic refractory pain syndromes. NMDA antagonists may modulate the CNS function, offering a novel approach to the treatment of chronic pain. Some studies suggest that ketamine, administered by intravenous infusion or orally, may be effective in relieving pain. However, intravenous ketamine may induce serious side effects such as vivid hallucination and psychosis. Recent reports suggest low dose ketamine may offer effective pain relief with remarkably few side effects.. ...
UT Southwestern Medical Center scientists have identified a key protein that helps trigger ketamines rapid antidepressant effects in the brain, a crucial step to developing alternative treatments to the controversial drug being dispensed in a growing number of clinics across the country.
TY - JOUR. T1 - Ketamine for analgosedation in critically ill patients. AU - Erstad, Brian L. AU - Patanwala, Asad E. PY - 2016/10/1. Y1 - 2016/10/1. N2 - Purpose The purpose of this narrative review is to provide practical and useful guidance for clinicians considering the use of intravenous ketamine for its analgosedative properties in adult, critically ill patients. Methods MEDLINE was searched from inception until January 2016. Articles related to the pharmacological properties of ketamine were retrieved. Information pertaining to pharmacology, pharmacokinetics, dosing regimens, adverse effects, and outcomes was obtained from relevant studies. Results Although the primary mechanism for ketamines pharmacological effects is N-methyl-D-aspartate blockade, there are several potential mechanisms of action. It has a very large volume of distribution due to its lipophilicity, which can lead to drug accumulation with sustained infusions. Ketamine has several advantages compared with conventional ...
A study confirms the antidepressant effects of intravenous ketamine at the standard 0.5 mg/kg dose and hints that a lower dose might also have some benefit with fewer side effects.
Preparation of the animals. A total of 45 adult Sprague Dawley rats of both sexes, weighing from 250 to 400 gm, were used in the present study. All surgical and animal care procedures adhered to the guidelines for the use and care of experimental animals of the Canadian Council of Animal Care. The Animal Care Committee of Laval University also approved our experimental protocol. The animals were first anesthetized with a solution of 10 cc ketamine hydrochloride (100 mg/ml) plus 1.5 cc xylazine (100 mg/ml) administrated intramuscularly (0.1 cc solution per 100 gm body weight). A local anesthetic (Xylocaine 2% or Marcaine 0.75%) was also administrated in the ears and forehead of the rats before their heads were placed in a stereotaxic apparatus (David Kopf Instruments, Tujunga, CA). The anterograde tracer biotin dextran amine (BDA) (Molecular Probes, Eugene, OR) was injected bilaterally in the dorsal or ventral tier of the SNc, the VTA, or the RRF using the stereotaxic coordinates of the atlas of ...

Ketamine hydrochloride is a quick-acting anesthetic that can cause intoxication, hallucinations, and even death when taken in dangerously high doses.
Even if severe hypoxia/ischemia did occur, it could not account for the neuroapoptosis response to ketamine because 4-6 h after ketamine administration, an increase in apoptotic profiles is evident both as a caspase-3 activation response and as ultrastructurally confirmed apoptotic morphology. However, when one intentionally induces hypoxia/ischemia and examines the developing brain 4-6 h later, there is no increase in apoptotic profiles, either by caspase-3 activation or ultrastructural criteria. It is illogical to argue that anesthesia-induced apoptosis is caused by hypoxia/ischemia if one cannot demonstrate that intentionally induced hypoxia/ischemia reproduces the anesthesia-induced apoptosis phenomenon. What one does find in the brain 4-6 h after hypoxia/ischemia, as we have demonstrated previously,3 and also very recently,4 is excitotoxic neurodegeneration. (See Young et al. 4 for a detailed presentation of evidence directly addressing and clarifying this issue.) Soriano et al. challenge ...
Commence infusion at 1ml/hr (60mcg/kg/hr) and increase by 1ml/hr every 6hours until a maximum dose of 4ml/hr (240 mcg/kg/hr) is reached. The maximum rate should be achieved by 18 hours from commencing infusion.. If the child has difficulty tolerating the increased rate changes at 6 hourly intervals this can be extended to 12 hour intervals, this decision will be made by the complex pain service. If the child is unable to tolerate 12 hour interval increases then the rate is maintained at the highest tolerable dose.. If the child shows a reasonable response from a lower rate than the recommended maximum of 4ml/hr, then the infusion is maintained at this lower dose. This decision will be made by the complex pain service.. ...

Results of this study show ketamine acts on the mu, kappa, and delta opioid receptors as an agonist (we already know ketamine acts on the NMDA receptor as an antagonist). The study conclusion shows that activation of the opioid receptors by ketamine is necessary for its antidepressant effects. The study proved the above findings by administering study patienst naltrexone (an opioid receptor antagonist) prior to the administration of IV ketamine therapy. Those subjects that received naltrexone prior to receiving the IV ketamine infusion therapy showed decreased effects of the ketamine on depressive symptoms.. Read More ...

Newcastles favorite dance punkers have returned with yet another killer single, K Bye. A short, sweet smash up tune which will no doubt be a fun dance (mosh) along at their huge up coming national tour! Opening with some real wide muted strings, K Bye is a tune that isnt out of place in the late 90s/early naughties Brooklyn rock scene with simple screechy vocals, super wide guitar riffs and deep low bass with plenty of gain and one of the catchiest opening lines of 2017, "I dont know what you said to me but it sounds like Ketamine." I have no doubt K Bye will be on playlists for years to come.. Frontman Joab Estley describes the tune, "The track was inspired a few years ago at a Newcastle house show-when I was a much younger, much more naive version of myself. It was a Sunday night, I had work in the morning, so I was just stopping in on my way home. Its subtly opening a dialogue about the inextricable links between illicit behaviour and underground youth subcultures-all wrapped up in a ...

Children Appropriate studies have not been performed on the relationship of age to the effects of ketamine injection in children younger than 16 years of age. Safety and efficacy have not been established. Older adults Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of ketamine injection in the elderly. However, elderly patients are more likely to have age-related kidney, liver, or ...
We previously found that subanesthetic doses of ketamine administered during the dark (active) period (DP) in rats strongly increased the integrated amplitude of the delta (1-4 Hz) electroencephalogram (EEG) in subsequent nonrapid eye movement (NREM) sleep. Here, we injected MK-801 into adult male Sprague-Dawley rats to test the hypothesis that such delta stimulation is characteristic of drugs that noncompetitively block the cation channel gated by the N-methyl-D-aspartate (NMDA) receptor. Injections of 0.3 and 0.5 mg/kg MK-801 in the middle of the DP produced waking intoxication for approximately 3 hr. In the following light period, NREM delta integrated amplitude was markedly increased in every rat (mean 55% increase after 0.5 mg/kg). A separate control experiment with 3-hr sleep deprivation in the mid-DP showed that the delta stimulation could not be attributed to sleep loss during MK-801 intoxication. Mechanisms by which NMDA cation channel blockade might stimulate NREM delta include a ...

TY - JOUR. T1 - Initial experience with iv ketamine infusion for treatment of post sternotomy pain in a patient with a total artificial heart. AU - Maher, Dermot P.. AU - Loyferman, Rusty. AU - Yumul, Roya. AU - Louy, Charles. PY - 2015/1/1. Y1 - 2015/1/1. N2 - The implantation of total artificial hearts (TAHs) via midline sternotomy for the treatment of severe biventricular cardiac dysfunction is associated with complex postoperative pain management. Ketamaine increases blood pressure by raising sympathetic outflow and cardiac ouput; however, ketamine is a direct vasodilator on isolated arterial tissues. In the setting of a TAH with a mechanically fixed cardiac output, a ketamine infusion for postoperative pain control has the potential to decrease blood pressure due to direct arterial vasodilation. We present the initial experience with a ketamine infusion in a patient with a TAH with minimal observed decreases in blood pressure and significantly improved postoperative pain.. AB - The ...
Acute pain management in the emergency department with low-dose ketamine may provide pain relief comparable with morphine at 30 minutes.
Our own clinical experience has been that many patients referred to our clinic have been on an SSRI for prolonged periods with little or no impact on their symptoms, and this has led us to investigate other potential pharmacotherapies, in particular the anticonvulsant lamotrigine. Lamotrigine acts at the presynaptic membrane to reduce the release of glutamate, and it has been shown to reverse depersonalisation-related phenomena induced by the N-methyl-d-aspartate (NMDA) receptor antagonist ketamine in healthy individuals (Anand et al, 2000). In the absence of large-scale randomised controlled trials, and in the presence of conflicting published data (see below), the efficacy of lamotrigine (whether as monotherapy or in conjunction with an SSRI) is not yet firmly established, but it is often our first-line treatment for the condition.. An initial study of lamotrigine monotherapy in four patients with primary depersonalisation found substantial benefits in all cases (Sierra et al, 2001), but a ...
