Activated charcoal is only given within one hour of anticholinergic ingestion. Physostigmine is given only if presenting both peripheral and central signs and symptoms of anticholinergic poisoning. [23] Physostigmine is a central and peripheral acting acetylcholinesterase inhibitor and generally given to patients with pure anticholinergic ...
Scopolamine, an anticholinergic drug, was used to block cholinergic activity in young adults and induce memory impairments similar to those present in the elderly. The memory impairments were reversed when treated with physostigmine , a cholinergic agonist.
Doxylamine is also a potent anticholinergic, meaning that it causes delirum at high doses—i.e., at much higher doses than recommended. [8] (Specifically it is an antagonist of the muscarinic acetylcholine receptors M 1 through M 5.) These sedative and deliriant effects have in some cases led to using the drug recreationally.
Anticholinergics (anticholinergic agents) are substances that block the action of the acetylcholine (ACh) neurotransmitter at synapses in the central and peripheral nervous system. [ 1 ] [ 2 ] These agents inhibit the parasympathetic nervous system by selectively blocking the binding of ACh to its receptor in nerve cells .

The main contraindication for ipratropium in any form is hypersensitivity to atropine and related substances. [20] [21]Conditions such as narrow-angle glaucoma, prostatic hyperplasia, or bladder neck obstruction are not necessarily contraindicators, but should be taken into account, particularly if the patient is receiving an anticholinergic by another route.
Diphenhydramine is a potent anticholinergic agent and potential deliriant in higher doses. This activity is responsible for the side effects of dry mouth and throat, increased heart rate , pupil dilation , urinary retention , constipation, and, at high doses, hallucinations or delirium .
The GI cocktail is a mixture of a viscous anesthetic, an antacid, and an anticholinergic. [1] [2] Common viscous anesthetics use are viscous lidocaine or xylocaine.Common antacids used are magnesium hydroxide, aluminum hydroxide, or simethicone (more commonly known as Mylanta or Maalox). [3]
