On the so-called psychopharmacological revolution: the discovery of chlorpromazine and the management of madness

Abstract This article analyzes the shortcomings and problems of the thesis that a true revolution took place in the field of biological psychiatry between 1952 and 1954 thanks to the discovery of chlorpromazine. To do so, it analyzes the discourses and strategies that led to the discovery of this drug, which became a model for the production of new psychopharmaceuticals. It seeks to understand, also, what is meant by “therapeutic efficacy” with regard to this drug.
