Insights

Cardiovascular medication (CVM) overdose cases were analyzed, revealing that antihypertensives, particularly calcium channel and beta-blockers, were most common. Accidental poisoning occurred in young children, while suicide attempts were prevalent in young adults.

Area of Science:

  • Emergency Medicine
  • Clinical Toxicology
  • Cardiology

Background:

  • Cardiovascular medications (CVMs) are widely used but pose risks when misused or overdosed.
  • Unconscious CVM use can lead to severe health consequences, including fatalities.
  • Understanding CVM exposure profiles is crucial for developing preventive strategies.

Purpose of the Study:

  • To characterize the demographic and clinical profile of patients admitted for CVM exposures.
  • To identify the types of CVMs most frequently involved in poisoning cases.
  • To determine the reasons for CVM exposure and associated clinical outcomes.

Main Methods:

  • Retrospective analysis of 105 CVM poisoning cases admitted to the Emergency Medicine Department.
  • Data collected included patient demographics, medication type, exposure route, reason for exposure, clinical effects, and outcomes.
  • Analysis focused on age groups, gender, and specific CVM classes.

Main Results:

  • Females constituted the majority (77.1%) of CVM exposure cases.
  • Accidental poisoning was most common in children aged 0-6 (64.3%), while suicide attempts predominated in the 19-29 age group (47.8%).
  • Calcium channel blockers (19.7%), beta-blockers (17.3%), and ACE inhibitors/diuretics (11.8%) were the most frequent CVMs involved. Most patients (59.1%) were asymptomatic, with altered consciousness being the most common symptom (18.6%).

Conclusions:

  • Antihypertensive drugs are the primary cause of CVM exposures.
  • Age-specific patterns exist for accidental vs. intentional CVM poisoning.
  • Further multi-centered studies are recommended to establish national epidemiological data and inform preventive measures for CVM exposures.

Pharmaceutical Poisoning: Potential Scenarios

Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Toxidromes: Clinical Features

Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...

Pharmaceutical Poisoning: Treatment Strategies

Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...
Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
Drug toxicity: Idiosyncratic Reactions01:16

Drug toxicity: Idiosyncratic Reactions

Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...

Drug Toxicity: Allergic Reactions

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
