What does antipsychotic mean?
An antipsychotic is a class of psychiatric medication used primarily to manage psychosis — a state involving hallucinations, delusions, and disorganized thinking most commonly associated with schizophrenia and bipolar disorder. The term functions both as a noun, referring to the drugs themselves, and as an adjective describing their effects. First-generation antipsychotics, beginning with chlorpromazine in the 1950s, transformed mental health care by making it possible for many patients to live outside institutions; later second-generation or 'atypical' antipsychotics were developed to reduce side effects such as movement disorders. Well-known examples include risperidone, olanzapine, quetiapine, and clozapine. In ordinary usage, the word appears most often in phrases like 'antipsychotic medication' and 'atypical antipsychotics'. It derives from Greek roots meaning 'against the mind or soul', reflecting its purpose of countering distorted mental experience. For anyone reading about mental health, understanding this term clarifies discussions of treatment options and how modern psychiatry manages serious mental illness.
A drug that relieves the symptoms of psychosis, such as hallucinations, delusions, and disordered thinking.
"The doctor prescribed a new antipsychotic to control her auditory hallucinations."
Often pluralized when referring to the class of drugs collectively.

The first antipsychotic was discovered by accident in the 1950s when a French surgeon noticed that a sedative he was testing made patients remarkably calm — and it went on to empty psychiatric wards across the world.

Etymology of antipsychotic
The word combines the prefix 'anti-', from Greek meaning 'against', with 'psychotic', which derives from the Greek 'psykhē', meaning breath, spirit, or mind. It entered English in the mid-twentieth century alongside the development of the first effective psychiatric medications, particularly after chlorpromazine's introduction around 1952. It shares its Greek root with cognates such as psychology, psychiatry, and psychic.
How antipsychotic is actually used
The term is standard in clinical and everyday medical contexts alike. 'Neuroleptic' is an older synonym still common in European medical literature, while 'major tranquilizer' is now considered dated. The word carries no strong stigma in itself, though discussion of psychiatric medication should remain sensitive to how it affects individuals.
