Antipsychotics are drugs that are used to treat symptoms of psychosis such as delusions (for example, hearing voices), hallucinations, paranoia, or confused thoughts. They are used in the treatment of schizophrenia, severe depression and severe anxiety. Antipsychotics are also useful at stabilizing episodes of mania in people with Bipolar Disorder.
Their main action is on dopamine receptors, reducing levels of excess dopamine. They may also affect levels of other neurotransmitters, namely acetylcholine, noradrenaline, and serotonin.
