Abstract

The primary objectives in the treatment of schizophrenia are to reduce the frequency and severity of psychotic exacerbation, ameliorate a broad range of symptoms, and improve functional capacity and quality of life. Treatment includes pharmacotherapy and a range of psychosocial interventions. Antipsychotics are the cornerstone of pharmacological treatment for schizophrenia. The sixty-five antipsychotics available in the world are classified into two major groups: first-generation (conventional) agents (FGAs) and second-generation (atypical) agents (SGAs). Whereas clozapine is found to be more efficacious than other agents among otherwise treatment-refractory schizophrenia patients, other differences in efficacy between antipsychotic agents are minor. There are, however, pronounced differences in adverse effect profiles among the 65 antipsychotic medications. Although the 14 SGAs differ "on average" from the 51 FGAs in terms of being associated with a lower risk of EPS and greater risk of metabolic side-effects, substantial variation within the two classes with regard to both risks and other relevant clinical properties undermines the categorical distinction between SGAs and FGAs. Choice of antipsychotic medication should be based on prior treatment response, individual preference, medical history and individual patient vulnerabilities. An individualized treatment approach with ongoing risk-benefit monitoring and collaborative decision-making is outlined. Even as rapid neuroscience advances promise revolutionary improvements in the future, a thoughtful and disciplined approach can provide enhanced outcomes for all schizophrenia patients today.

摘要

治疗精神分裂症的主要目标是减少精神病恶化的频率和严重程度,改善广泛的症状,并提高功能能力和生活质量。治疗包括药物治疗和一系列心理社会干预。抗精神病药是精神分裂症药物治疗的基石。目前世界上有 65 种抗精神病药,可分为两类:第一代(传统)药物(FGAs)和第二代(非典型)药物(SGAs)。氯氮平被发现对其他治疗抵抗的精神分裂症患者比其他药物更有效,但抗精神病药物之间的疗效差异较小。然而,在 65 种抗精神病药物中,不良反应谱存在明显差异。虽然 14 种 SGA 在与 EPS 风险降低和代谢副作用风险增加相关方面平均与 51 种 FGA 不同,但这两类药物在风险和其他相关临床特性方面存在很大差异,这削弱了 SGA 和 FGA 之间的分类区别。抗精神病药物的选择应基于既往治疗反应、个体偏好、病史和个体患者的脆弱性。本文概述了一种个体化的治疗方法,包括持续的风险-效益监测和协作决策。即使快速的神经科学进步有望在未来带来革命性的改善,但深思熟虑和有纪律的方法可以为今天所有精神分裂症患者提供更好的结果。
