Brief overview of chlorpromazine (Thorazine)

Chlorpromazine, commonly known by the brand name Thorazine, is a psychiatric medication that belongs to a class of drugs known as phenothiazines. It was first developed in the 1950s and quickly became one of the first effective antipsychotic medications used to treat conditions such as schizophrenia.


Chlorpromazine was first synthesized in 1950 by Rhône-Poulenc, a French pharmaceutical company. It was initially developed as an antihistamine but was later found to have powerful antipsychotic properties. In 1951, it was introduced into clinical practice by French surgeon Henri Laborit for use as a preoperative sedative. It was subsequently used to treat patients with various mental health conditions, revolutionizing the field of psychiatry.

Mechanism of action

Chlorpromazine works by blocking dopamine receptors in the brain, specifically the D2 receptors. By doing so, it helps to reduce the symptoms of psychosis, such as hallucinations and delusions. It also has sedative and antiemetic properties, making it useful for managing agitation and nausea.


Chlorpromazine is primarily used to treat schizophrenia and other psychotic disorders. It may also be used to manage bipolar disorder, severe anxiety, and severe behavioral problems in children. In some cases, it is used off-label to treat severe hiccups and intractable nausea and vomiting.

Side effects

Like all medications, chlorpromazine can cause side effects. Common side effects include drowsiness, dizziness, dry mouth, blurred vision, and constipation. More serious side effects may include neuroleptic malignant syndrome, tardive dyskinesia, and extrapyramidal symptoms.


According to a survey conducted by the National Institute of Mental Health, approximately 1 in 100 people in the United States have schizophrenia, which is one of the main indications for chlorpromazine treatment. The average cost of chlorpromazine medication can range from $10 to $50 per month, depending on the dosage and formulation.
Chlorpromazine remains an important medication in the treatment of various mental health conditions, despite the development of newer antipsychotic drugs. It has helped countless individuals manage their symptoms and improve their quality of life.
