- 使用更新的神经网络模型,描述非多巴胺类药物的机制,包括肌肉素 (M4,M1) 受体激活剂 (例如,与托斯一起的xanomeline) 和跟踪胺相关受体1 (TAAR1) 激活剂 (例如,ulotaront),使用更新的神经网络模型.
- 对新第三代抗精神病药物的第三期临床试验数据的介绍.
主要成果:
- 与第二代药物相比,在D2和D3受体上具有部分激动性的新型抗精神病药物在精神分裂症的积极,消极和认知症状方面表现出优异的改善,耐受性良好.
- M4/M1受体激动剂和TAAR1激动剂显著增强精神分裂症的负面症状和认知功能.
- 这些新的非多巴胺类药物比第二代抗精神病药物更好地改善了负面症状和认知能力.
结论:
- 第三阶段临床研究证实了新第三代抗精神病药物的有效性.
- 有前途的药物,如卡里普拉辛,布雷克斯皮普拉,卢马特佩龙,乌洛托朗特和克萨诺梅林与特洛斯一起,显示出比第二代抗精神病药物更好的治疗效果.

Antipsychotic Drugs: Therapeutic Uses and Side Effects
815
Antipsychotic drugs primarily block dopamine and serotonin receptors and cholinergic, adrenergic, and histaminergic receptors, thereby reducing hallucinations and delusions in conditions like schizophrenia. However, they can trigger unwanted extrapyramidal effects such as dystonias, Parkinson-like symptoms, and tardive dyskinesia.
Despite these side effects, antipsychotics are used therapeutically for various purposes, including managing schizophrenia, preventing nausea and vomiting, curbing...

Psychosis and Antipsychotic Drugs: Overview
885
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Antipsychotic Drugs: Typical and Atypical Agents
837
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

Schizophrenia
863
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those...

Biological Causes of Schizophrenia
572
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Combined Effects of Drugs: Antagonism
11.7K
The combined effects of drugs can result in various interactions, of which an important type is antagonism. Antagonism is a mechanism where one drug inhibits or counteracts the effects of another drug. Antagonism can occur through various means, including receptor binding, allosteric modulation, functional interaction, chemical reactions, and pharmacokinetic processes.
The most common type is receptor antagonism, where one drug acts as an antagonist to block the effects of another drug by...
