neuroleptanalgesia

A form of analgesia achieved by the concurrent administration of a neuroleptic and an analgesic. Anxiety, motor activity, and sensitivity to painful stimuli are reduced; the person is quiet and indifferent to the environment and surroundings. If nitrous oxide with oxygen is also administered, neuroleptanalgesia can be converted to neuroleptanesthesia.

An intense analgesic and amnesic state produced by the combination of narcotic analgesics and neuroleptic drugs.

A state of quiescence, reduced awareness and analgesia produced by the simultaneous administration of a neuroleptic agent, e.g. acepromazine, and a narcotic analgesic, e.g. meperidine. Fixed-dose combinations used extensively in veterinary science are droperidol–fentanyl citrate and etorphine–acepromazine.
