Neuroleptic drugs have long been the cornerstone of treatment for patients with psychotic disorders, such as schizophrenia. This approach to therapy has proved effective in alleviating the distressing symptoms which disturb and disrupt the lives of patients and their families. Neuroleptics are particularly useful for relieving the so-called 'positive' symptoms of psychosis which include delusions, hallucinations and thought disorder. Once these symptoms have passed, many patients are advised to continue taking neuroleptic medication in order to prevent relapse, and it is not unusual for patients to be on neuroleptic medication for several years. This paper describes the composition and effects of the more commonly used neuroleptics.
抗精神病药物长期以来一直是治疗精神疾病患者（如精神分裂症患者）的基石。这种治疗方法已被证明在减轻困扰患者及其家人生活的痛苦症状方面是有效的。抗精神病药物对于缓解精神病的所谓“阳性”症状特别有用，这些症状包括妄想、幻觉和思维紊乱。一旦这些症状消失，许多患者会被建议继续服用抗精神病药物以防止复发，患者服用抗精神病药物数年的情况并不罕见。本文描述了更常用的抗精神病药物的成分和作用。
