Metabolic side effects have been found earlier during treatment with second-generation antipsychotics. Among those disturbances serum lipids are less investigated. We conducted a prospective, open study in schizophrenia patients in order to compare body weight and serum lipids during treatment with amisulpride, ziprasidone, clozapine or olanzapine over a period of 4 weeks. Body mass index, total cholesterol and triglycerides increased in patients treated with clozapine and olanzapine whereas high-density lipoprotein cholesterol decreased in those patients. In patients treated with amisulpride or ziprasidone, we found a decrease in body mass index and total cholesterol whereas high-density lipoprotein cholesterol increased. Our results indicate that treatment with ziprasidone and amisulpride is more favourable than treatment with clozapine and olanzapine with respect to the risk to induce weight gain and hyperlipidaemia. These results are important with regard to the increased risk for cardiovascular complications in patients with schizophrenia.

Effect of antipsychotics on the focal adhesion pathway.
World J Biol Psychiatry
January 2025
School of Medicine, IMPACT, Institute for Innovation in Physical and Mental Health and Clinical Translation, Deakin University, Geelong, Australia.
Unlabelled: Focal adhesions and their dynamic nature are essential for various physiological processes, including the formation of neurites, synaptic function and plasticity. Alterations in these processes have been associated with schizophrenia and bipolar disorder.
Objectives: This study aimed to explore the impact of pharmacological treatments used for bipolar disorder and schizophrenia on the expression of genes involved in the focal adhesion pathway, addressing a gap in understanding the interaction between medication effects and disease pathophysiology.
Second-generation antipsychotic-induced dystonia: Analysis using the Japanese Adverse Drug Event Report (JADER) database.
Psychiatry Clin Neurosci
January 2025
Department of Psychiatry, Nagoya University Graduate School of Medicine, Nagoya, Japan.
Aim: This study aimed to explore the comparative risks for dystonia among different second-generation antipsychotics (SGAs), the influence of sex, and the relationship between the time-to-onset of dystonia and its outcomes.
Methods: We analyzed data from the Japanese Adverse Drug Event Report database from April 2004 to November 2023. Cases involving oral SGAs, excluding clozapine, were extracted.
Negative Symptoms in Schizophrenia: An Update on Research Assessment and the Current and Upcoming Treatment Landscape.
CNS Drugs
January 2025
New York State Psychiatric Institute, 1051 Riverside Drive, New York, NY, 10032, USA.
Article Synopsis
- The negative symptoms of schizophrenia, like lack of emotion and motivation, are hard to treat and significantly impact daily functioning.
- This review highlights current research on treatment options for these symptoms, categorizing them into different types and evaluating various assessment scales.
- Although no treatments are conclusively proven as the best for these symptoms, some off-label and investigational medications show promise, including cariprazine and memantine, and further research is needed to explore new therapeutic possibilities.
Sexual dysfunctions associated with antipsychotic drug intake: a retrospective analysis of the FDA adverse events reporting system (FAERS).

Sexual dysfunctions (SD) are common and debilitating side effects of antipsychotics. The current study analyzes the occurrence of antipsychotic-related SD using data from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). FAERS was queried for sexual dysfunction adverse events (encoded by 35 different MedDRA preferred terms) secondary to amisulpride, aripiprazole, chlorprothixene, clozapine, haloperidol, loxapine, olanzapine, pipamperone, quetiapine, risperidone, and ziprasidone from 2000 to 2023.

Metabolic syndrome (MetS) is a cluster of metabolic abnormalities, including visceral obesity, dyslipidemia, and insulin resistance. In this regard, visceral white adipose tissue (vWAT) plays a critical role, influencing energy metabolism, immunomodulation, and oxidative stress. Adipose-derived stem cells (ADSCs) are key players in these processes within vWAT.
