Abstract
Oral administration of ET-495 was found to cause worsening of psychiatric status in 4 out of 7 schizophrenic patients, and to induce a paranoid state and a syndrome of auditory hallucinosis in 2 non-schizophrenics. These observations were compatible with the hypothesized role of dopamine in schizophrenia. However, these psychotogenic effects were far less dramatic than those noted in other studies with amphetamine, methylphenidate or L-Dopa. Possible explanations for this differing psychotogenic potency of receptor stimulators versus presynaptic agonists are presented. Intravenous ET-495 and apomorphine did not show psychotogenic effects.
