Kaplan Pharm Flashcards
choline uptake is inhibited by (hemicholinium/botulinum toxin)
hemicholinium
(hemicholinium/botulinum toxin) interacts with synaptobrevin to prevent ACh release
botulinum toxin
(hemicholinium/botulinum toxin) is used in blepharospasm, strabismus/hyperhydrosis, dystonia
botulinum toxin
M receptor activation (increases/decreases) CV function
decreases
M receptor activation (increases/decreases) secretions and (increases/decreases) smooth muscle contractions
increases both
all M receptor activators and blockers are (specific/nonspecific)
nonspecific
blood vessels are solely innervated by (symp/parasymp), so stimulation of autonomic ganglia results in vasoconstriction
sympathetic nervous system
the GI tract is dominated by (symp/parasymp) so ganglionic stimulation causes increased GI motility and secretions
parasymp

organophosphates
(edrophonium/physostigmine/neostigmine and pryidostigmine/donepezil/organophosphates): treats glaucoma, antidote in atropine overdose, enters CNS
physostigmine
(edrophonium/physostigmine/neostigmine and pryidostigmine/donepezil/organophosphates): treats ileus, urinary retention, myasthenia, reversal of nondepolarizing NM blockers
neostigmine and pyridostigmine
(edrophonium/physostigmine/neostigmine and pryidostigmine/donepezil/organophosphates): treats myasthenia; used to differentiate myasthenia from cholinergic crisis
edrophonium
(edrophonium/physostigmine/neostigmine and pryidostigmine/donepezil/organophosphates): treats Alzheimer disease
donepezil

benztropine, trihexyphenidyl
(atropine/tropicamide/ipratropium and tiotropium/scopolamine/benztropine and trihexyphenidyl): used in motion sickness, causes sedation and short-term memory block

tropicamide
(atropine/tropicamide/ipratropium and tiotropium/scopolamine/benztropine and trihexyphenidyl): antispasmodic, antisecretory, management of AChE inhibitor overdose, antidiarrheal, opthalmology
atropine
Fenoldopam is a D1 (agonist/antagonist) used for severe HTN
agonist
(beta/alpha) receptors are usually more sensitive to activators than (alpha/beta) receptors
beta more sensitive than alpha
