Psychosis and Antipsychotic Drugs: Overview01:28

Psychosis and Antipsychotic Drugs: Overview

327
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: Therapeutic Uses and Side Effects

260
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: Goals of Pharmacotherapy

165
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Drug Therapy01:28

Drug Therapy

68
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.

Antipsychotic Drugs: Typical and Atypical Agents01:21

Antipsychotic Drugs: Typical and Atypical Agents

246
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...

Antidepressant Drugs: MAOIs and Other Agents

272
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...

Summary

Antipsychotic medication use significantly increases fracture risk in both men and women. This study suggests regular bone health monitoring for individuals taking antipsychotics is crucial.

Area of Science:

  • Bone Health Research
  • Pharmacological Studies
  • Epidemiology

Background:

  • Antipsychotic medications are linked to reduced bone mineral density and quality.
  • Existing research suggests a potential association between antipsychotic use and skeletal fragility.

Purpose of the Study:

  • To investigate the association between antipsychotic drug use and fracture risk.
  • To analyze fracture risk in a population-based sample of Australian adults.

Main Methods:

  • A case-control study design was employed, comparing individuals with fractures (cases) to those without (controls).
  • Data on medication use, medical history, and lifestyle factors were collected via self-report.
  • Multivariable binary logistic regression analysis was used to adjust for potential confounders.

Main Results:

  • Antipsychotic use was associated with a 2.3-fold increased fracture risk in women and a 3.0-fold increased risk in men, after adjustments.
  • The association remained significant even after excluding non-fragility fractures and participants with schizophrenia.

Conclusions:

  • Antipsychotic use is a significant risk factor for fractures in both sexes.
  • Regular bone health assessment is recommended for patients using antipsychotic medications.
