N2O gas vs ketamine
This is a comparative study of two dissociative anesthetics—nitrous oxide (N2O) and ketamine—which work by blocking NMDA receptors to produce anesthesia and analgesia.
This is a comparative study of two dissociative anesthetics—nitrous oxide (N2O) and ketamine—which work by blocking NMDA receptors to produce anesthesia and analgesia. Used for Anesthesia and analgesia (comparative efficacy study), Acute pain management.
At a glance
| Generic name | N2O gas vs ketamine |
|---|---|
| Sponsor | Seoul National University Hospital |
| Drug class | NMDA receptor antagonist (dissociative anesthetic) |
| Target | NMDA receptor |
| Modality | Small molecule |
| Therapeutic area | Anesthesia / Analgesia |
| Phase | FDA-approved |
Mechanism of action
Both N2O and ketamine are dissociative agents that antagonize N-methyl-D-aspartate (NMDA) glutamate receptors, leading to rapid onset of anesthesia, analgesia, and dissociation. N2O is a volatile gas with rapid kinetics, while ketamine is a parenteral agent with longer duration and additional monoaminergic effects. This appears to be a clinical comparison study rather than a single drug entity.
