Antipyschotics are a type of psychoactive drug which are used to treat a range of mental health problems including psychosis, anxiety and dementia.

Antipsychotics are also known as neuroleptics or major tranquillisers.

There are two main types of antipsychotics

  • the older, typical or conventional antipsychotics, which include aliphatic phenthiazine, butyrophenone (Haloperidol or Haldol), chlorpromazine, fluphenazine, molindone, piperidine phenthiazine, trifluoperazine, thiothixene, and trifluperidol
  • the newer, atypical antipsychotics, which include aripiprazole, olanzapine, quetiapine, risperidone, and ziprasidone.

Some people think that antipsychotics can also be used to treat some of the more challenging problems faced by individuals with autism including aggression, irritability, hyperactivity, self injury, and stereotyped behaviour.
