Insights

Long-term antipsychotic use in young people increases metabolic risks but not cardiovascular risks. This study analyzed data from over 48,000 individuals across four countries, highlighting the importance of monitoring metabolic health during extended antipsychotic treatment.

Area of Science:

  • Pharmacovigilance
  • Pediatric Pharmacology
  • Cardiovascular Epidemiology

Background:

  • Antipsychotic medications are widely used in children and young adults.
  • Limited real-world data exists on the comparative risks of cardiovascular and metabolic events associated with antipsychotic use in this population across different countries.
  • Understanding these risks is crucial for optimizing treatment strategies and patient safety.

Purpose of the Study:

  • To evaluate the risks of cardiovascular and metabolic events in children and young adults receiving antipsychotic treatment.
  • To compare these risks across different exposure durations and geographical regions.

Main Methods:

  • A multinational self-controlled case series (SCCS) study was conducted using nationwide databases from Taiwan, Korea, Hong Kong, and the UK.
  • The study included approximately 100 million individuals, focusing on patients aged 6-30 years exposed to antipsychotics.
  • Cardiovascular events (stroke, ischemic heart disease, myocardial infarction) and metabolic events (hypertension, type 2 diabetes, dyslipidemia) were analyzed across various antipsychotic exposure windows.

Main Results:

  • The analysis included 48,515 individuals.
  • A statistically significant increased risk of metabolic events was observed only with long-term exposure (more than 90 days), with a pooled incidence rate ratio (IRR) of 1.29 (95% CI 1.20-1.38).
  • No significant association was found between antipsychotic exposure and cardiovascular events across any exposure window.

Conclusions:

  • Long-term exposure to antipsychotics is associated with an increased risk of metabolic events in children and young adults.
  • Antipsychotic use in this age group did not appear to trigger cardiovascular events.
  • These findings underscore the need for vigilant metabolic monitoring in pediatric and young adult patients on extended antipsychotic therapy.

Antipsychotic Drugs: Typical and Atypical Agents

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...

Psychosis and Antipsychotic Drugs: Overview

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...

Drug Therapy

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Psychological and Sociocultural Causes of Schizophrenia01:29

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Antidepressant Drugs: MAOIs and Other Agents

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...
