Chlorpromazine (CPZ), marketed under the brand names Thorazine and Largactil among others, is an antipsychotic medication. [6] It is primarily used to treat psychotic disorders such as schizophrenia . [ 6 ]
Jean Delay (14 November 1907, Bayonne – 29 May 1987, Paris) was a French psychiatrist, neurologist, writer, and a member of the Académie française (Chair 17).. His assistant Pierre Deniker conducted a test of chlorpromazine on the male mental ward where Delay worked, and the two published their findings (quickly, with what has been called academic gamesmanship) in 1952.

Simone Courvoisier was a French experimental pharmacologist who, while the head of pharmacology at Rhône-Poulenc in the 1950s, investigated the use of the antipsychotic medication chlorpromazine. [ 1 ] [ 2 ] She discovered that the compound promazine had sedating properties despite not being an antihistamine like its precursor promethazine ...
A related concept to D2 potency is the concept of "chlorpromazine equivalence", which provides a measure of the relative effectiveness of antipsychotics. [ 13 ] [ 14 ] The measure specifies the amount (mass) in milligrams of a given drug that must be administered in order to achieve desired effects equivalent to those of 100 milligrams of ...
Henri Laborit (21 November 1914 – 18 May 1995) was a French surgeon, neurobiologist, writer and philosopher. In 1952, Laborit was instrumental in the development of the drug chlorpromazine, published his findings, and convinced three psychiatrists to test it on a patient, resulting in great success.
Chlorpromazine (brand name: Thorazine) passed clinical trials and became the first antipsychotic medication approved for the treatment of both acute and chronic psychosis. Although the mechanism of action was not discovered until 1963, the administration of chlorpromazine marked the advent of the dopamine antagonist , or first generation ...
Pierre Deniker (16 February 1917, in Paris – 17 August 1998) was involved, jointly with Jean Delay and J. M. Harl, in the introduction of chlorpromazine (Thorazine), the first antipsychotic used in the treatment of schizophrenia, in the 1950s. [1] Thorazine had been used in surgical procedures peri-operatively as an anti-nausea medication in ...
However, chlorpromazine proved to reduce the effects of psychosis in a more effective and specific manner than lobotomy, even though it was known to be capable of causing severe sedation. The underlying neurochemistry involved has since been studied in detail, and subsequent antipsychotic drugs have been developed by rational drug design.
