autonomic drugs Flashcards
Direct acting cholinergi agonists, muscarinic
muscarine, piocarpine, bethanechol
Direct acting chol agonists. nicotinic
nicotine, succinylcholine
direct acting chol agonists. partial nicotinic agonists
varenicline
indirect acting chol. agonists
physostigmine, neostigmine, demecarium, edrophonium, echothipophate, donepezil, tacrine
how do indirect acting chol agonists work
all of them inhibit AChE to prolong the effect of ACH
which indirect chol agonists have lon lasting effects
physostigmine, neostigmine, demecarium
which indirect chol agonist has a short effect
edrophonium
what is echothiophate used for
glycoma, myasthenia gravis, sgogren’s syndrome, is phosphorylates AChE and can inhibit hundreds of hours. also affects choleno receptors of muscles
which indirect chol antagonists treat alzheumer’s
donepezil, tacrine
what does pralidoxime do
if given early, can revearse any permanent damage caused by organophosphate AChE inhibitors
what are irreversibel AChE inhibitors
Malathion (insecticide) Sarin (nerve gas)
Antimuscarinic agents
atropine, scopolamine, ipratropium
atropine
antimuscarinic agent, it blocks a lot of DUMBBELS effect if given soon after exposer, lasts 7-10 days
scopolamine
antimuscarinic agent, blocks dumbbels lasts 3-7 days. used to treat motion sickness
ipratropium
antimuscarinic agent. used in asthma
derifenicin
used to treat urinary incontinece
tiotropium
asthma
antinicotinic agents
succinycholine, pancuronium, atracurium, rocuronium, sugammadex
succinylcholine
depolarizing antinicotinic agent. long duration, intially activates receptor, eventually there is muscle hyperpolarization lead to paralysis (used in surgery)
non depolarizing antinicotinic agents
pancuronium, atracurium, rocuronium, skeletal muscle ACh receptor blockers, all derived from curare
