The neuroleptic (antipsychotic) activity of phenotropil was studied in an experimental animal model. Phenotropil had a marked neuroleptic activity in models of positive (apomorphine-induced verticalization test) and negative (5-HTP-induced hyperkinesis test) symptoms of psychoses as well as in the m-cholinergic pathway hyperactivation (arecoline-induced tremor test). The compound markedly antagonized haloperidol catalepsy. Used in a single dose or as a course treatment, phenotropil did not provoke aggression nor intensify it. In contrast to typical and atypical antipsychotics, phenotropil had no sedative action and other adverse effects. It exhibited a positive effect on exploratory behavior and motor activity, had anxiolytic and antidepressant action.
