Cholinergic agents are compounds which mimic the action of acetylcholine and/or butyrylcholine. [1] In general, the word " choline " describes the various quaternary ammonium salts containing the N , N , N -trimethylethanolammonium cation .
Flaccid paralysis resulting from cholinergic crisis can be distinguished from myasthenia gravis by the use of the drug edrophonium (Tensilon), as it only worsens the paralysis caused by cholinergic crisis but strengthens the muscle response in the case of myasthenia gravis. (Edrophonium is a cholinesterase inhibitor, hence increases the ...
A “beneficial” inflammatory response is limited, resolves in 48–72 hours, and does not spread systemically. The cholinergic anti-inflammatory pathway provides a braking effect on the innate immune response which protects the body against the damage that can occur if a localized inflammatory response spreads beyond the local tissues, which ...
A parasympathomimetic drug, sometimes called a cholinomimetic drug [1] or cholinergic receptor stimulating agent, [2] is a substance that stimulates the parasympathetic nervous system (PSNS). [ 3 ] [ 2 ] These chemicals are also called cholinergic drugs because acetylcholine (ACh) is the neurotransmitter used by the PSNS.
An acetylcholine receptor (abbreviated AChR) or a cholinergic receptor is an integral membrane protein that responds to the binding of acetylcholine, a neurotransmitter. Classification [ edit ]
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.
The cholinergic neuron may also play a role in time memory, and the ability of an individual to form a memory around a certain time of day, which is known as "time stamping". [8] The cholinergic system is characterized by high acetylcholine release during the active phase of an individual’s circadian rhythm. [8]
Mydriasis can be induced via modulation of adrenergic or cholinergic signalling. Drugs that can cause mydriasis include: Stimulants (typically monoaminergics) such as amphetamines, cocaine, MDMA, and mephedrone. Anticholinergics such as diphenhydramine, atropine, hyoscyamine, and scopolamine antagonize the muscarinic acetylcholine receptors in ...
