Abstract:
A toxicologic syndrome, or toxidrome, is a distinct pattern of effects of poisoning. Well-defined toxidromes are the opioid, anticholinergic, cholinergic and sympathomimetic, and an additional described toxidrome is GABAergic. These toxidromes are named for the receptor effects causing their specific clinical findings, and knowledge of toxidromes allows rapid pattern recognition of specific poisonings. In this review, toxidromes and the initial assessment and general approach to management of acute poisoning are discussed. This article details the receptor-level effects of the poisoning, key clinical signs and symptoms and the role antidotes play in treatment. Clinical resources such as Toxbase and others exist to provide detailed guidance on clinical management of poisoning.
Insights
Recognizing toxidromes, distinct poisoning patterns like opioid or anticholinergic, aids rapid diagnosis. Understanding receptor effects and management strategies is crucial for acute poisoning cases.
Area of Science:

Prevention of Further Absorption of Poison
Antidotes
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...
Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
Anticholinesterase Agents: Poisoning and Treatment
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...
Types of Toxins
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...
Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
Renal excretion is the...
