Anticholinergic Syndrome (also known as Anticholinergic Syndrome) The term ″central anticholinergic syndrome″ refers to a psychosis or delirium that occurs suddenly as a result of the suppression of central cholinergic transmission. The following is taken from Haddad and Winchester’s Clinical Management of Poisoning and Drug Overdose (Fourth Edition), published in 2007.
The anticholinergic syndrome is caused by the competitive antagonism of acetylcholine at muscarinic receptors in the central and peripheral nervous systems. This toxidrome is characterized by an agitated (hyperactive) delirium characterized by bewilderment, restlessness, and picking at imagined things, all of which are typical of this condition.

What is anticholinergic toxicity (toxidrome)?
Anticholinergic toxicity, also known as anticholinergic syndrome, is the term used by experts to describe this deadly impact.In certain situations, the term ″toxidrome″ is used, which is a mixture of the words ″toxicity″ and ″syndrome,″ and it refers to the combination of the two words.Toxic effects on the anticholinergic system might arise unintentionally or as the consequence of a planned poisoning effort (e.g.overdose).
What are Anticholinergics used to treat?
Anticholinergics are used to treat a wide range of medical disorders, including the following: Alkaloids from belladonna are a combination of acetycholine and phenobarbital that are used to treat stomach cramps associated with irritable bowel syndrome (IBS) and spastic colon.
What causes anticholinergic syndrome?
Accidental consumption of an anticholinergic medication, medical noncompliance, or geriatric polypharmacy are all potential causes of anticholinergic syndrome. The use of topical eye drops has also been linked to systemic consequences. The intake of a wide variety of prescription and over-the-counter drugs is frequently associated with the development of anticholinergic syndrome.
What is an anticholinergic effect?
Anticholinergic medications work by inhibiting the function of a neurotransmitter known as acetylcholine.Inhibition of nerve impulses responsible for involuntary muscular movements and numerous physiological processes is achieved by using this medication.In addition to treating overactive bladder, these medications can also be used to treat other illnesses such as Chronic Obstructive Pulmonary Disease (COPD).
How do you treat anticholinergic syndrome?
A remedy for anticholinergic toxicity is physostigmine salicylate, which is available over-the-counter. In addition, physostigmine is the only reversible acetylcholinesterase inhibitor capable of directly counteracting the CNS signs of anticholinergic toxicity; it is an uncharged tertiary amine that is capable of crossing the blood-brain barrier with high efficiency.
How do you test for anticholinergic toxicity?
- In febrile patients, blood and urine cultures are performed
- Analysis of serum chemistry and electrolyte levels, which may offer information as to the presence of intoxicating substances and co-ingestants.
- Patients with psychomotor agitation should have their creatine kinase (CK) levels checked to rule out the possibility of concomitant rhabdomyolysis.
When should I take anticholinergic?
The dosage should be taken 30 minutes before meals and 30 minutes before bedtime. It is possible that your doctor will adjust the dose if it is necessary.
What is an example of an anticholinergic effect?
Some of the more common symptoms are dry mouth, constipation, urine retention, intestinal blockage, dilated pupils, impaired vision, elevated heart rate, and reduced sweating, among other things (Table 1).
What are side effects of anticholinergic drugs?
- Anticholinergic drugs can have negative side effects. Dry lips, blurred vision, dry eyes, constipation, and urinary retention are all symptoms of this condition.
- Symptoms of postural hypotension include dizziness caused by a decrease in blood pressure upon standing up
- Problems with cognition (confusion)
- heart rhythm disruption
Can you overdose on anticholinergics?
Accidental or purposeful overdoses of substances having anticholinergic action have been documented. Due to the availability of anticholinergics and the fact that many drugs have anticholinergic side effects, this is an essential issue to discuss.
Can anticholinergic effects be reversed?
Anticholinergic effects are seen in a wide range of medicines. On the whole, it is believed that cognitive impairment caused by anticholinergic medications may be reversed by discontinuing the medicine. However, a small number of studies have suggested that anticholinergic drugs may be related with an increased risk of developing dementia.
Is Benadryl an anticholinergic?
Benadryl, like other first-generation (older) antihistamines, has the potential to make you extremely drowsy. As a result, it is also utilized as a sleep aid in some cases. Furthermore, Benadryl is classed as an anticholinergic medication. Other medications in this family are used to treat mental health issues and bladder illness, among other conditions.
Do anticholinergics dry secretions?
* Also referred to as a ‘death rattle.’ Anticholinergic (antimuscarinic) actions may cause patient discomfort (e.g., dryness, urine retention), but they do not dry secretions that are already present in the patient’s system.
Do anticholinergics increase heart rate?
Effects on the anticholinergic system The most prevalent side effects are urinary retention, constipation, dry mouth, confusional states, and tachycardia. When muscarinic blocking of vagal tone on the heart occurs, the resultant rise in heart rate is often indicated as a sinus tachycardia on the electrocardiogram.
What are the side effects of anticholinergic agent?
A dry mouth, low blood pressure, and disorientation are all possible side effects of anticholinergic drugs. They can also induce agitation, confusion, and memory issues. Although it was previously believed that these adverse effects would be transient, new research suggests that long-term use of anticholinergics may result in cognitive deterioration and dementia.
What are the adverse effects of anticholinergic drugs?
Extreme sleepiness and dizziness are common side effects. – high temperature – hallucinations that are severe – a sense of disorientation – difficulty breathing – clumsiness and slurred speech – rapid heartbeat – flushing and warmth of the skin – headache
Why is neostigmine used with anticholinergic?
- The neuromuscular junction is a connection between two muscles. Anticholinesterases are enzymes that prolong the period that acetylcholine spends in the synaptic cleft.
- Cardiovascular system. Anticholinesterases are known to enhance the effects of vagal stimulation on the heart.
- The respiratory system
- the gastrointestinal system
- the secretory glands
- the endocrine system
