Summary
A new EIDOS classification system for adverse drug effects is proposed. It details the mechanism of drug-induced harm, complementing existing clinical classifications for better drug safety.
Area of Science:
- Pharmacology
- Drug Safety
- Toxicology
Background:
- Current classification of adverse drug effects lacks mechanistic detail.
- Understanding drug-induced harm mechanisms is crucial for improving patient safety.
Purpose of the Study:
- To propose a comprehensive mechanistic classification for adverse drug effects.
- To introduce the EIDOS (Extrinsic, Intrinsic, Distribution, Outcome, Sequela) framework.
Main Methods:
- Development of the EIDOS classification system.
- Integration of EIDOS with the existing DoTS (Dose, Time, Susceptibility) clinical classification.
Main Results:
- The EIDOS system categorizes adverse drug effects based on five mechanistic elements: Extrinsic and Intrinsic chemical species, Distribution, Outcome, and Sequela.
- EIDOS provides a mechanistic understanding of how adverse drug effects occur.
Conclusions:
- The EIDOS classification offers a detailed mechanistic view of adverse drug reactions.
- Combined with DoTS, EIDOS provides a comprehensive framework for understanding and managing adverse drug effects in drug development, regulation, and clinical practice.

01:00Drug 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...
01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
01:27Effects of Chemicals: Overview
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...
01:24Drug 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...
01:30Drug 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...
01:25Drug Classes and Categories
Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...
