    Insights

    This study analyzed 827 autopsy cases to understand lethal adverse drug reactions (ADRs). Only 25% of cases met the criteria for lethal ADRs, highlighting the complexity of drug-induced pathology.

    Area of Science:

    • Forensic Pathology
    • Clinical Pharmacology
    • Toxicology

    Background:

    • Adverse drug reactions (ADRs) pose a significant challenge in healthcare.
    • Autopsy studies provide crucial insights into the mechanisms and outcomes of ADRs.
    • Differentiating true ADRs from other causes of mortality is complex.

    Purpose of the Study:

    • To determine the relative frequency of drugs causing ADRs.
    • To identify the primary sites of action for these drugs.
    • To characterize the pathological processes induced by ADRs.

    Main Methods:

    • Analysis of 827 autopsy cases with documented adverse drug reactions.
    • Categorization of cases into seven groups based on ADR criteria and lethality.
    • Inclusion of morphologic findings and a specialized analytic algorithm for diagnostic validation.

    Main Results:

    • Only 25% of the studied cases met the strict criteria for lethal adverse drug reactions.
    • Nondrug factors significantly influenced the occurrence and manifestation of many ADRs.
    • The study identified specific drugs, their target organs, and induced pathological changes.

    Conclusions:

    • A minority of autopsy cases with suspected ADRs definitively meet criteria for lethality.
    • Morphologic data and advanced analytical methods enhance the accuracy of ADR diagnosis.
    • Understanding the interplay of drug and nondrug factors is crucial for ADR management.

    Drug Regulation

    Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

    Pharmacovigilance

    Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
    This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
    In some cases, there...
    Drug Toxicity: Overview01:00

    Drug Toxicity: Overview

    Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

    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: Drug–Drug Interaction01:30

    Drug toxicity: Drug–Drug Interaction

    Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...
    Pharmaceutical Poisoning: Potential Scenarios01:26

    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...
