Anticholinergic drugs are used to treat a variety of conditions: Dizziness (including vertigo and motion sickness-related symptoms) Extrapyramidal symptoms, a potential side-effect of antipsychotic medications; Gastrointestinal disorders (e.g., peptic ulcers, diarrhea, pyloro spasm, diverticulitis, ulcerative colitis, nausea, and vomiting)
Cholinesterase inhibitors (ChEIs), also known as anti- cholinesterase, are chemicals that prevent the breakdown of the neurotransmitter acetylcholine or butyrylcholine. This increases the amount of the acetylcholine or butyrylcholine in the synaptic cleft that can bind to muscarinic receptors, nicotinic receptors and others.
Acetylcholinesterase inhibitors ( AChEIs) also often called cholinesterase inhibitors, [ 1] inhibit the enzyme acetylcholinesterase from breaking down the neurotransmitter acetylcholine into choline and acetate, [ 2] thereby increasing both the level and duration of action of acetylcholine in the central nervous system, autonomic ganglia and ...
A muscarinic receptor antagonist ( MRA ), also called an antimuscarinic, is a type of anticholinergic agent that blocks the activity of the muscarinic acetylcholine receptor. The muscarinic receptor is a protein involved in the transmission of signals through certain parts of the nervous system, and muscarinic receptor antagonists work to ...
"Given all the research evidence, physicians might want to consider alternatives to anticholinergic medications, if available, when working with older patients," a researcher told CNN.
Cholinergic blocking drugs are a group of drugs that block the action of acetylcholine (ACh), a neurotransmitter, in synapses of the cholinergic nervous system. [1] They block acetylcholine from binding to cholinergic receptors, namely the nicotinic and muscarinic receptors. These agents have broad effects due to their actions in nerves located ...
The term generally refers to anticholinergic drugs, which are substances that inhibit the function of the neurotransmitter acetylcholine. [ 1 ] Common examples of deliriants include plants of the genera Datura and Brugmansia , both containing scopolamine , as well as higher than recommended dosages of diphenhydramine ( Benadryl ).
These medications can also cause sedation (sleepiness), weight gain, and anticholinergic effects (blocking a chemical messenger in the brain that sends messages to nerves and muscles like dry ...
