They cause miosis and ciliary muscle contraction. However, consuming too much choline may have unpleasant and harmful side effects, such as low blood pressure, sweating, fishy body odor, diarrhea, nausea, vomiting, and liver damage ( 36 ). Anticholinesterases have actions both at the nicotinic and the muscarinic receptors, and even when accompanied by an antimuscarinic agent, they produce undesirable autonomic responses.

Anticholinergic Drugs: Uses, Effects & Complete List - Addiction Group However, ACh's activity is greatly hindered by both acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. They cause ACh to accumulate in the vicinity of cholinergic nerve terminals and thus are potentially capable of producing effects equivalent to excessive stimulation of cholinergic receptors throughout the central and peripheral nervous systems. If anticholinesterase medications are not sufficient, plasmapheresis or intravenous immune globulin (IVIG) may be used, but the benefits are transient.
