What was the name of the first medication utilized as an antipsychotic?

Chlorpromazine is recognized as the first medication used as an antipsychotic. Introduced in the 1950s, it marked a significant breakthrough in the treatment of psychotic disorders, particularly schizophrenia. Prior to its development, options for managing severe mental illnesses were quite limited and often ineffective. Chlorpromazine works primarily by blocking dopamine receptors in the brain, which is thought to help alleviate symptoms such as delusions and hallucinations. Its introduction revolutionized psychiatric treatment and paved the way for the development of other antipsychotic medications. This historical significance solidifies its place as the first antipsychotic medication in clinical use.
