Effect of fusaric acid on tardive dyskinesia and mental state in psychogeriatric patients

Abstract

The effect of fusaric acid 150–50 mg daily on tardive dyskinesia and mental state was studied in 15 chronic psychogeriatric patients. The patients' previous drug treatment was maintained unchanged during the experiment. Fusaric acid significantly relieved oro‐facial dyskinesia, tremor, and rigidity, and it improved the mental state of the patients (BPRS). Akathisia was exacerbated, but this change was not significant. Akinesia and anxiety were not altered.
