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 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] Pore blocking of the NMDA receptor is responsible for the anesthetic, analgesic, and psychotomimetic effects of ketamine.
Ketamine affects another neurotransmitter, glutamate, which is known as an excitatory neurotransmitter. ... Ketamine’s antidepressant effects are part of what prompted researchers to explore ...
The effects of psychedelics on neuroplasticity appear to be dependent on serotonin 5-HT 2A receptor activation, as they are abolished in 5-HT 2A receptor knockout mice. [7] Non-hallucinogenic serotonin 5-HT 2A receptor agonists, like tabernanthalog and lisuride , have also been found to increase neuroplasticity, and to a magnitude comparable to ...
An implicit premise in neuropsychopharmacology with regard to the psychological aspects is that all states of mind, including both normal and drug-induced altered states, and diseases involving mental or cognitive dysfunction, have a neurochemical basis at the fundamental level, and certain circuit pathways in the central nervous system at a higher level.
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.
Evidence is growing for the use of atypical psychedelics such as ketamine for treating depression in terminally ill patients, with repeated IV administration having the most therapeutic effect. [62] These studies did not have any patients experience any serious adverse effects; however, ketamine-induced ulcerative cystitis is a concern for ...
