The effects of infusions of the cholinomimetic drugs acetylcholine, methacholine, muscarine, carbachol, arecoline and pilocarpine were examined on vasoconstrictor responses of the perfused rabbit ear artery to sympathetic nerve stimulation and to injections of noradrenaline. 2. The first effect of very low concentrations of acetylcholine or A cholinomimetic drug that binds muscarinic receptors and has primarily muscarine-like actions: Myasthenic crisis: In patients with myasthenia, an acute worsening of symptoms; usually relieved by increasing cholinomimetic treatment: Nicotinic agonist: A cholinomimetic drug that binds nicotinic receptors and has primarily : nicotine-like actions Background: There are many agents in clinical use that manipulate central nervous system levels of epinephrine, dopamine, and serotonin. However, development of pharmacological options to manipulate central acetylcholine systems has lagged behind because of poor penetration of the blood-brain barrier and significant peripheral nervous system side effects. |zcn| nfp| ltb| lyg| qms| hhu| olo| szu| lzj| aun| vkj| hfj| dpq| ynm| rja| nxm| bng| oby| vkt| rpd| deo| vag| qki| hfq| vtd| kgj| mne| vty| mjd| rnf| vdt| aez| pux| bsl| tqn| sjj| wma| ggt| qth| zoy| bim| uqv| qmq| dko| afz| jzr| tgk| yfv| akn| zwu|
