Chlorpromazine discovery/introduction

It can be argued that the introduction of lithium salts into the practice of psychiatry in 1949 heralded the beginning of psychopharmacology, as it predated the discovery of chlorpromazine, imipramine, monoamine oxidase inhibitors and resperine. Lithium came into clinical use serendipitously, the Australian psychiatrist Cade having by chance given it to a small group of manic patients and found that it had beneficial effects.
