Clinical effects include tachycardia, delirium, hallucinations, mydriasis, dry skin and mucous membranes, urinary retention, decreased gastric motility, and occasionally hyperthermia. This syndrome can occur at any age, but the elderly are at higher risk because of their increased sensitivity to all drug effects and because antiholinergics are so frequently precribed for older people (see box). Cumulative Anticholinergic Burden and its Predictors among Older Adults with Alzheimer's Disease Initiating Cholinesterase Central anticholinergic syndrome is a rare syndrome precipitated by drugs or substances that increase the release of serotonin (levodopa, and carbidopa-levodopa association, amphetamines and derivatives, cocaine), impair its reuptake (selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants, valproate, carbamazepine, Abruptly ceasing anticholinergic medications may sometimes lead to anticholinergic discontinuation syndrome characterised by nausea, sweating, urinary urgency, anxiety, tachycardia, orthostatic hypotension and apparent deterioration of sleep quality. Our case describes a central anticholinergic syndrome following 1. Anticholinergic drugs may cause unwanted effects such as dry mouth, constipation, ataxia, flushed skin, confusion, disorientation and slurred speech. -Antihistamines, antidepressants, scopolamine, hyoscyamine, atropine, and plants containing anticholinergic alkaloids (Datura, Belladonna) can precipitate an anticholinergic syndrome. 1 In anesthesia practice, the syndrome originally was described in connection with drugs having central anticholinergic actions.

JAVAD SHAMSAI, M. Serotonin is a neurotransmitter that regulates mood, behavior, and other physiological functions. We describe 2 cases of CAS that occurred a disorder created by the actions of anticholinergic drugs, which have caused unwanted effects on the central and peripheral nervous systems. Symptoms include: dry mouth, constipation, ataxia, flushed skin, confusion, disorientation, slurred speech, and memory problems. Additionally, recreational drugs and over-the-counter (OTC) drugs (eg, 3,4-methylenedioxy-methamphetamine [MDMA; ecstasy], bath salts, and St John's wort) have been associated with serotonin syndrome. Info The clinical picture of the central cholinergic blockade, known as the central anticholinergic syndrome (CAS), is identical with the central symptoms of atropine intoxication. 7,11,99 It is an abstract construct combining various concepts, clinical signs, and symptoms that aims to relate signs of CNS hyperexcitability with purported drug-induced serotonin excess. Its symptoms can include accelerated heartbeat ( tachycardia ), overheating ( hyperthermia ), drowsiness, blurred vision, dry skin and mouth, and occasionally even more severe symptoms, such as hallucinations and seizures [ 26 ]. [1] The symptoms can range from mild to severe, and are potentially fatal. Five potentially life threatening toxidromes (sympathomimetic overdose, anticholinergic overdose, serotonin syndrome, neuroleptic malignant syndrome, and malignant hyperthermia) can all present with overlapping clinical features: hyperthermia, altered mental status/seizures, rhabdomyolysis. Serotonin syndrome results from drug-induced over-stimulation of serotonin receptors in the CNS and is characterized by a triad of CNS dysfunction, Anticholinergic Syndrome. , antipsychotic medications) Medicines with anticholinergic properties. Two brief case reports illustrate the presentation and diagnosis of the syndrome.

Central anticholinergic syndrome A wide range of drugs have been implicated in cases of central anticholinergic syndrome. The selection of pharmacologic treatment for irritable bowel syndrome (IBS) remains symptom directed. Serotonin is a chemical that the body produces naturally. A comparison of physostigmine and benzodiazepines for the treatment of anticholinergic poisoning. 20 Given the protean ways that CNS hyperexcitability can present, combined with the Typically, these compounds are used to block the acetylcholine-mediated activation of nicotinic and/or muscarinic acetylcholine receptors (MAChRs). Implicated medications include anticholinergics such as atropine, benztropine, and Central anticholinergic syndrome is defined as an ab- Diagnosis rests on clinical features, exclusion of solute or relative reduction in cholinergic activity in other conditions, and a positive response to a the central nervous system[1]. When a significant amount of an anticholinergic is taken into the body, a toxic reaction known as acute anticholinergic syndrome may result. Central anticholinergic syndromeduring recovery is essentially a diagnosis of exclusion and can be confirmed only Central anticholinergic syndrome often goes unrecognized since the symptoms of the condition often do not present in a well-defined pattern and may present with a wide array and severity of symptoms (eg, anticholinergic psychosis) 12 (Table III). significant anticholinergic effects, which when taken with known anticholinergic medication can increase the risk of Many medication groups e. Its management, including psychological support and the Experts have referred to this poisonous effect as anticholinergic toxicity or anticholinergic syndrome. It may be due to a substance inhibiting the effects of stimulation of the postganglionic fibre of the parasympathetic nervous system, as occurs with atropine. , overhang of sedatives), an impairment of consciousness can also be an adverse side effect of drugs. The classical anticholinergic clinical syndrome is a manifestation of competitive antagonism of acetylcholine at peripheral and central muscarinic receptors. Meningitis or encephalitis may look a lot like serotonin syndrome. Timing and frequency for This is known as anticholinergic syndrome, poisoning, or toxicity and requires immediate medical attention. Anticholinergics are extensively used in medicine, such as, prior to anesthesia, as a prophylactic for preventing motion sickness, in symptomatic control of Parkinson's disease, in abnormal slowing of the heart in poisoning with organophosphates and other cholinergic Anticholinergics are drugs that oppose the effects of acetylcholine. Alkaloids, such as atropi Serotonin syndrome (SS) (also referred to as serotonin toxicity) is a potentially life-threatening drug-induced toxidrome associated with increased serotonergic activity in both the peripheral (PNS) and central nervous systems (CNS). Health care professionals should do the following: Be familiar with common drugs or drug combinations that may induce this condition; These four elements suggest an anticholinergic toxidrome. overdose).
