We then suggest some future research directions for the investigation of the fast-acting antidepressant effect of ketamine.Meng LiMartin WalterNeuropathology of Drug Addictions and Substance MisuseLi M, Walter M (2016). The Acute and Chronic Effects of Ketamine as Revealed by Noninvasive Brain ...
Ketamine commonly and rapidly induces dissociative and other altered states of consciousness (ASCs) in humans. However, the neural mechanisms that contribute to these experiences remain unknown. We used functional neuroimaging to engage key regions of th
Emergency practitioners can consider giving ketamine 4-6 mg/kg IM (500 mg for most adults). Once given, it is important to closely monitor the patient for adverse effects and that the examination continue to determine the etiology of the patient’s agitation. This is a preview of subscription...
Motor impairment (tilt-plane test) was used to investigate whether the noncompetitive N-methyl-D-aspartate (NMDA) antagonist ketamine prevents the development of chronic and acute tolerance to ethanol. Rats were treated with ethanol or saline in the presence and absence of ketamine (separate groups...
Occlusion of dopamine-dependent synaptic plasticity in the prefrontal cortex mediates the expression of depressive-like behavior and is modulated by ketamine Article Open access 30 June 2022 Orexin receptor antagonists reverse aberrant dopamine neuron activity and related behaviors in a rodent model of...
Ketamine is a phencyclidine derivative.[9]It is a noncompetitive antagonist of glutamate at the N-methyl-D-aspartate (NMDA) receptor-cation channel complex and leads to anesthetic effects on the central nervous system.[10]It also stimulates opioid receptors within the insular cortex, putamen, and...
This is advantageous for patients suffering from severe pain prior to surgery or are using a strong opioid. The S enantiomer of ketamine used for anesthesia is more powerful than racemic ketamine. The ideal dose of ketamine for pain relief is not yet known, and its adverse effects on the ...
In an effort to maximize analgesia and to minimize the rate of side effects, epidural NMDA receptor antagonists, especially ketamine, may be co-administered with opioids. This study investigated whether ketamine had beneficial effects on fentanyl- or morphine-induced antinociception in an acute pain ...
