The antipsychotic potency of the partial opiate agonist buprenorphine
was evaluated in 10 neuroleptic-free schizophrenic patients suffering from
frequent hallucinations, delusions, and severe formal thought disorders.
Buprenorphine had a pronounced antipsychotic effect, which lasted about 4
hours, in patients with schizophreniform disorders (N = 4) and paranoid
schizophrenia (N = 3).
