How Chlorpromazine Transformed Psychiatric Care
- Chlorpromazine emerged from antihistamine research and was repurposed in 1952 to calm psychotic agitated patients at St. Anne's Hospital in Paris.
- Pierre Deniker's trial of 38 patients found reduced hallucinations and delusions, which catalyzed global adoption and deinstitutionalization.
Deinstitutionalization Was Both Medical And Economic
- Deinstitutionalization after antipsychotics was driven both by clinical improvement and government cost-saving.
- Lack of community resources left many discharged patients homeless with inadequate follow-up, a problem still seen today.
Dopamine Blockade Explains Most Antipsychotic Efficacy
- First-generation antipsychotics share antipsychotic efficacy primarily through dopamine D2 receptor blockade.
- Dopamine antagonism explains roughly 92–93% of variance in their clinical efficacy, underpinning the dopamine hypothesis of psychosis.
