02 Feb 2018 --- The common food preservative sodium benzoate improves symptoms in clozapine-resistant schizophrenia patients, according to a new study published in Biological Psychiatry. The randomized, double-blind, placebo-controlled trial led by Hsien-Yuan Lane, M.D., Ph.D., of China Medical University, Taiwan, showed that adding on sodium benzoate to the antipsychotic clozapine improved symptoms in patients who did not see results with any other medications, providing a new option for the hardest-to-treat patients.
