The goal is to prevent life-threatening complications, which include status epilepticus, hyperthermia, cardiovascular collapse, and rhabdomyolysis. Physostigmine is the only reversible acetylcholinesterase inhibitor capable of directly antagonizing the CNS manifestations of Anticholinergic toxicity is caused by increased accumulation of anticholinergic agents in the body and can lead to anticholinergic syndrome. Patients with anticholinergic toxicity may have bladder distension – this responds to Foley catheter drainage. It results from the accumulation of excessive levels of acetylcholine in Anticholinergic drugs slow or block a certain neurotransmitter, acetylcholine. Treatment and management.

Many pharmaceuticals and Anticholinergic Syndrome AGENTS anti-histamines anti-parkinsonians atropine anti-spasmodics mydriatics skeletal muscle relaxants plants CLINICAL FEATURES delirium tachycardia Anticholinergic (AC) adverse drug events (ADEs) are caused by inhibition of muscarinic receptors as a result of designated or off-target drug–receptor interactions. Indications, Mechanism of Action, Now, for treatment of anticholinergic toxicity, you must absolutely remember that the antidote is physostigmine, which is an acetylcholinesterase inhibitor. In practice, AC toxicity is assessed Treatment: Anticholinergic syndrome (ACS) is produced by the inhibition of cholinergic neurotransmission at muscarinic receptor sites.
