Chlorpromazine is an antipsychotic medication primarily used to treat symptoms of schizophrenia and other mental health disorders. It works by affecting certain chemicals in the brain, particularly dopamine, which helps to reduce hallucinations, delusions, and agitation. Originally developed in the 1950s, Chlorpromazine was one of the first medications used in psychiatry, marking a significant advancement in the treatment of mental illness. It can also be prescribed for severe anxiety and nausea, but it may cause side effects such as drowsiness, dry mouth, and weight gain.
