Ketamine-assisted psychotherapy (KAP) is the use of prescribed doses of ketamine as an adjunct to psychotherapy sessions. KAP shows significant potential in treating mental disorders such as treatment-resistant depression (TRD), anxiety, obsessive–compulsive disorders (OCD), post-traumatic stress disorders (PTSD), and other conditions.

Psychoactive drugs exert their sensory and behavioral effects almost entirely by acting on neurotransmitters and by modifying one or more aspects of synaptic transmission. Neurotransmitters can be viewed as chemicals through which neurons primarily communicate; psychoactive drugs affect the mind by altering this communication.
Ketamine affects another neurotransmitter, glutamate, which is known as an excitatory neurotransmitter. ... Ketamine’s antidepressant effects are part of what prompted researchers to explore ...
Ketamine is a mixture of equal amounts of two enantiomers: esketamine and arketamine. Esketamine is a far more potent NMDA receptor pore blocker than arketamine. [11] Pure blocking of the NMDA receptor is responsible for the anesthetic, analgesic, and psychotomimetic effects of ketamine.
Unlike traditional antidepressants that target the neurotransmitters serotonin and/or norepinephrine, ketamine targets glutamate — the most abundant chemical messenger in the brain, Feifel said.
Ketamine infusions have been a game-changer for many with treatment-resistant depression and other mental health issues. But when Matthew Perry died from “acute effects of ketamine” a year ago ...
Ketamine and PCP were observed to produce significant similarities to schizophrenia. Ketamine produces more similar symptoms (hallucinations, withdrawal) without observed permanent effects (other than ketamine tolerance). Both arylcyclohexamines have some(uM) affinity to D2 and as triple reuptake inhibitors.
NMDA receptor antagonists induce a state called dissociative anesthesia, marked by catalepsy, amnesia, and analgesia. [1] Ketamine is a favored anesthetic for emergency patients with unknown medical history and in the treatment of burn victims because it depresses breathing and circulation less than other anesthetics.
