Chlorpromazine
Chlorpromazine (CPZ) — marketed as Thorazine among others — is a dopamine antagonist of the typical anti-psychotic class of medications possessing additional antiadrenergic, anti-serotonergic, anticholinergic and antihistaminergic properties used to treat schizophrenia. First synthesized on December 11, 1951, chlorpromazine was the first drug developed with specific antipsychotic action and would serve as the prototype for the phenothiazine class of drugs, which comprises several other agents. The introduction of chlorpromazine during the 1950s has been described as the single greatest advance in the history of psychiatric care, improving the prognosis of people in psychiatric hospitals.Chlorpromazine works on a variety of receptors in the central nervous system, producing potent anticholinergic, antidopaminergic, antihistaminic, and antiadrenergic effects. Both the clinical indications and side effect profile of CPZ are determined by the broadness of its action: its anticholinergic properties cause constipation, sedation, and hypotension but also help relieve nausea. It also has anxiolytic (anxiety-relieving) properties. Its antidopaminergic properties can cause extrapyramidal symptoms, such as akathisia (restlessness, where the patient walks almost constantly, despite having nowhere to go due to mandatory confinement) and dystonia. It is known to cause tardive dyskinesia, which can be irreversible. In acute settings, it is often administered as a syrup, which has a faster onset of action than tablets, and it can also be given by intramuscular injection. IV administration is very irritating and is not advised; its use is limited to severe hiccups, surgery, and tetanus.Chlorpromazine is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system.
