Summary
Tricyclic antidepressant poisoning, often mixed with other substances, led to suicide attempts in 98 patients over a decade. Depression and psychopathy were primary causes, with a 5% mortality rate, particularly in elderly women with heart failure.
Area of Science:
- Toxicology
- Psychiatry
- Epidemiology
Context:
- A decade-long study (1989-1998) analyzed 98 patients presenting with suicidal poisoning.
- Tricyclic antidepressants (TCAs) were the primary agent in 30 cases and involved in mixed ingestions in 68 others.
- Mixed intoxications frequently involved benzodiazepines, phenothiazines, barbiturates, and alcohol.
Purpose:
- To investigate the characteristics and outcomes of suicidal poisoning involving tricyclic antidepressants.
- To identify the primary psychiatric conditions and co-ingestants associated with TCA overdoses.
- To assess the mortality rate and risk factors in this patient cohort.
Summary:
- The study included 98 patients (47 male, 51 female, mean age 35) treated for suicidal TCA poisoning.
- Commonly associated conditions included depression (66%) and psychopathy/sociopathy (18%).
- Five patients (5%) died, with three elderly females with congestive heart failure succumbing to mixed TCA, benzodiazepine, and barbiturate poisoning.
Impact:
- Highlights the significant role of depression and psychopathy in suicidal TCA poisoning.
- Underscores the increased mortality risk in elderly patients with pre-existing cardiac conditions and mixed overdoses.
- Informs clinical management and public health strategies for antidepressant overdose prevention and treatment.
