Which statement describes the dissociative class included in the material?

• A. Ketamine and tiletamine-zolazepam are dissociatives used as anesthesia
• B. They are opioids
• C. They are benzodiazepines
• D. They are barbiturates

Answer: (A)

Dissociatives produce a trance‑like anesthesia with analgesia and amnesia while the patient may still maintain some reflexes and airway control. Ketamine is the classic example, and tiletamine-zolazepam is a fixed combination where tiletamine provides the dissociative effect and analgesia and zolazepam adds sedation and muscle relaxation. This makes them used for anesthesia, which is exactly what the statement describes. They’re distinct from opioids, benzodiazepines, and barbiturates in their primary classification, though the combination product does include a benzodiazepine component; the dissociative class itself centers on NMDA receptor antagonism and the dissociated, analgesic state.
