Synopsis

Opiate-like neuropeptides, such as beta endorphin, have been implicated in the aetiology of schizophrenic symptoms; and the relief of some symptoms, particularly auditory hallucinations, has been reported after injection of naloxone. An opiate antagonist, naloxone 1·6 mg, and placebo were administered in a double-blind, crossover design to 13 constantly hallucinating schizophrenic patients. Naloxone was found to be no different from placebo in its effect.
