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.
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. However, reversing memory impairments in AD patients may not be this easy due to ...
It should only contain pages that are agonists of cholinergic receptors or lists of agonists of cholinergic receptors, as well as subcategories containing those things (themselves set categories). Topics about agonists of cholinergic receptors in general should be placed in relevant topic categories .
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)
The cholinergic system is a vital nervous pathway, where cholinergic neurons synthesize, store and release the neurotransmitter ACh. The main receptors that convert the ACh messages are the cholinergic muscarinic acetylcholine receptors, neuronal and muscular nAChRs. When looking back at evolutionary history, ACh is considered to be the oldest ...
Drugs such as the neuromuscular blocking agents bind reversibly to the nicotinic receptors in the neuromuscular junction and are used routinely in anaesthesia. Nicotinic receptors are the primary mediator of the effects of nicotine. In myasthenia gravis, the receptor at the neuromuscular junction is targeted by antibodies, leading to muscle ...
According to their site of actions, cholinergic blocking drugs can be classified into two general types — antimuscarinic and antinicotinic agents. [1] Antimuscarinic agents (also known as muscarinic antagonists), including atropine and hyoscine, block acetylcholine at the muscarinic acetylcholine receptors.
This is a list of adrenergic drugs. These are pharmaceutical drugs , naturally occurring compounds and other chemicals that influence the function of the neurotransmitter epinephrine (adrenaline). Receptor ligands
