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
sugammadex
non depolarizing antinicotinic agent, reverses blockade by rocuronium by binding it directly
botulinum toxin type A
antinicotinic agent, inhibitor of ACh release, muscle paralytic agent. used cosmetically, treats muscle spasms…tics, strabismus, nystagmus
epinephrine
adrenergic agonist, acts on all adregergic receptors (alpha and beta)
agents that activate alpha 1 receptor
phenylephrine, tetrahydrozoline, naphazoline
pheylephrine
adrenergic agonist, activates alpha 1 receptor, decreases intranasal congestion
tetrahydrozoline
adrenergic agonist, activatesalpha 1 receptor, decreases intranasal congestion
naphazoline
adrenergic agonist, activates alpha 1 receptor, decreases intranasal congestion
agents that activate alpha 2 receptors
clonidine, alpha methyl norepinephrine
clonidine
adrenergic agonist, alpha 2, decrease symp. outflow from CNS. used to treat hypertension
alpha methyl norepinephrine
adrenergic agonist, alpha 2. decrease symp. outflow from CNS, used to treat hypertension.
agents that activate beta 1 receptor
norepinephrine, dobutamine
agents that activate beta 2 receptors
metaproterenol, terbutaline, fenoterol, aluterol. bronchodilation for treating asthma
indirect acting amines, which induce the release of NE from nerve terminals
amphetamine, methamphetamine, tyramine, pheylpropanolamine, pseudo-ephedrine
amphetamine/methamphetamine
indirect acting amines, which induce the release of NE from nerve terminals
tyramine
indirecting acting amines, which inuce the release of NE from nerve terminals
phenylpropanolamine
indirect acting amines, which induce the release of NE from nerve terminals
pseudoephedrine
indirect acting amines, which induce the release of NE from nerve terminals
