Antipsychotic
Antipsychotics (also known as neuroleptics or major tranquilizers) are a class of psychiatric medication primarily used to manage psychosis (including delusions, hallucinations, or disordered thought), in particular in schizophrenia and bipolar disorder, and are increasingly being used in the management of non-psychotic disorders (ATC code N05A). The word neuroleptic originates from the Greek word νεῦρον neuron (""nerve"") and λῆψις lepsis (""seizure"", ""fit"", ""occupation"").First-generation antipsychotics, known as typical antipsychotics, were discovered in the 1950s. Most second-generation drugs, known as atypical antipsychotics, have been developed more recently, although the first atypical antipsychotic, clozapine, was discovered in the 1950s and introduced clinically in the 1970s. Both generations of medication tend to block receptors in the brain's dopamine pathways, but atypicals tend to act on serotonin receptors as well.Antipsychotics are more effective than placebo in treating symptoms of psychosis, but some people do not respond fully or even partly to treatment. Their use is associated with significant side effects, most notably movement disorders and weight gain.
