The first anti-psychotic drug

In the first half of the 20th century, most mentally ill patients were locked away in psychiatric hospitals and asylums. Those suffering from severe mental illnesses like schizophrenia, were often sedated or restrained. Shock therapies were standard treatments. Then in France in the 1950s, a new drug was discovered which dramatically reduced psychotic symptoms in many patients. It was called Chlorpromazine. Soon it was being used around the world.
