Summary
Antipsychotic drug use in psychiatric patients may increase the risk of venous thrombosis. This finding is supported by autopsy data and a case-control study, highlighting a potential link between these medications and blood clots.
Area of Science:
- Psychiatry
- Pharmacology
- Thrombosis Research
Background:
- A significant proportion of pulmonary embolism deaths in psychiatric patients were linked to idiopathic causes.
- Previous literature suggested a connection between antipsychotic use and venous thrombosis.
Purpose of the Study:
- To investigate the potential association between antipsychotic medication and the risk of developing venous thrombosis.
- To determine if antipsychotic drugs are a risk factor for venous thromboembolism in psychiatric populations.
Main Methods:
- Analysis of autopsy reports from psychiatric patients who died from pulmonary embolism.
- Historical literature review on antipsychotic use and venous thrombosis.
- Re-analysis of data from the Leiden Thrombophilia Study (LETS), a case-control study.
Main Results:
- Five out of ten psychiatric patients with fatal pulmonary embolism had documented antipsychotic drug use.
- Historical German literature (1953-1977) indicated increased venous thrombosis incidence with chlorpromazine and related drugs.
- In the LETS study, four cases of venous thrombosis were associated with antipsychotic drug use, compared to none in the control group.
- Recent epidemiological studies corroborate these findings.
Conclusions:
- The use of antipsychotic drugs in psychiatric patients appears to be associated with an increased risk of venous thrombosis.
- This association warrants further investigation and clinical consideration for patient safety.

01:28Psychosis 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 symptoms in all...
01:21Antipsychotic 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...
01:21Antipsychotic Drugs: Therapeutic Uses and Side Effects
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...

01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
01:29Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
01:28Drug 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.
