Abstract:
Anticholinergic syndrome is a febrile toxidrome characterized by the suppression of cholinergic neurotransmission in muscarinic receptors. A prerequisite for its development is that pharmacological agents must be lipophilic and capable of crossing the blood-brain barrier to block muscarinic cholinergic receptors. Triggers of anticholinergic toxidrome include alkaloids from over 2,000 species of plants and fungi, antipsychotics, antidepressants, antiparkinsonian drugs, antispasmodics, ocular and antihistamine medications, general and local anesthetics, which are often prescribed in combinations

Undesirable effects of hypolipidemic statins in rodents are characterised by neurobehavioural alterations with changes in the cholinergic/cholinesterase and neurotropic systems.

Summary New/novel psychoactive substances (NPS) are substances of varying chemical structures and, in their physical forms, are taken and ingested and exhibit many diverse drug interactions.

Identifying NPS users is difficult because of the constantly changing range of new drugs available, which poses analytical challenges in finding sufficie

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 c

Anticholinergic toxicity and neuroleptic malignant syndrome (NMS) are common toxidromes in medical emergencies. However, their co-occurrence, resulting in a dual toxidrome, is rare and presents significant diagnostic and therapeutic challenges.

He was diagnosed with a dual toxidrome of anticholinergic storm and NMS. Treatment of NMS included lorazepam and bromocriptine.

Organophosphate (OP) poisoning is a frequent toxicological emergency worldwide, particularly in low- and middle-income countries. Because the characteristic cholinergic toxidrome involves multiple systems, the absence of a clear history of exposure and clinical suspicion may lead to a disastrous misdiagnosis.
