- adj.describing a group of drugs used to treat severe mental disorders (psychoses), including schizophrenia and mania; some are administered in small doses to relieve anxiety. Formerly known as major tranquillizers, antipsychotic drugs include the phenothiazines (e.g. chlorpromazine), butyrophenones (e.g. haloperidol), and thioxanthenes (e.g. flupentixol). Side-effects of antipsychotic drugs can include extrapyramidal effects, sedation, antimuscarinic effects, weight gain, and ECG changes (see electrocardiogram). The atypical antipsychotics are a group of more recently developed drugs that are associated with fewer extrapyramidal effects than conventional antipsychotics: they include clozapine, risperidone, olanzapine (Zyprexa), and quetiapine (Seroquel). Current NICE guidelines support the use of atypical antipsychotics as first-line treatment for schizophrenia.
