A review of nicotinic acid, N-methylated indoleamines and schizophrenia
Abstract:
The hypothesis that endogenously formed, N-methylated metabolites of indoleamines may play a role in the pathogenesis of schizophrenia was reviewed. Although N-methylated indoleamines can be produced in vivo and have significant psychotomimetic effects, there is little evidence for a specific increase in the methylation of indoleamines in schizophrenic patients. It was noted that even if the relationship between schizophrenia and N-methylated indoleamines had existed, nicotinic acid would not be an appropriate therapeutic agent.
