Schizophrenia
Research from The British Journal of Psychiatry found that amisulpride and olanzapine were the most helpful of the drugs they had tested for, and also other studies had tested for, but that comparing 1st generation and 2nd generation drugs for treatment, there wasn't very much improvement. Second generation are intended to be better at treating schizophrenia. This study included 22 428 patients and 11 antipsychotic drugs.
