Area of Science:

  • Neuroscience
  • Psychiatry
  • Pharmacology

Background:

  • Ketamine, a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist, is widely used as an anesthetic.
  • It exhibits mood-altering properties and has demonstrated rapid antidepressant effects in studies.
  • However, ketamine's therapeutic potential is complicated by its significant reinforcing and toxic effects, leading to abuse.

Purpose of the Study:

  • To review the epidemiology, pharmacology, neurochemistry, and treatment strategies for ketamine abuse.
  • To discuss the challenges and potential of ketamine in treating psychiatric disorders.
  • To explore the neurobiological mechanisms underlying ketamine's effects and its abuse potential.

Main Methods:

  • Literature review synthesizing existing research on ketamine's effects, abuse, and treatment.

  • Discussion of neurochemical pathways, including NMDA receptor antagonism and dopamine release.
  • Exploration of potential therapeutic interventions and future research directions.

    • Main Results:

    • Ketamine abuse causes severe individual and societal harm, including disrupted learning and memory.
    • A proposed mechanism involves blocking NMDA receptors on GABA neurons, leading to dopamine release.
    • Currently, no specific treatments exist for ketamine-induced peripheral toxicity.

    Conclusions:

    • Ketamine presents a dual profile: potential antidepressant and anxiolytic effects versus significant abuse liability and toxicity.
    • Ketamine psychotherapy is emerging as a potential treatment for other substance use disorders.
    • Further research is crucial to understand ketamine's mechanisms and develop effective treatments for its abuse and associated harms.
