Autonomic Drugs Flashcards
Vesamicol mech
blocks ACh packaging into vesicles
Bethanechol: type, effect, uses
Acetylcholine direct agonist, activates bowel and bladder (resistant to esterase), post operative ileus/urine retention
Carbachol: type, effect, uses
direct ACh agonist, exact mimic of ACh, glaucoma, pupillary contraction, relief of high IOP
Pilocarpine: type, effect, uses
ACh direct agonist, stimulates sweat/tears/saliva, used in glaucoma
Methacholine: type, effect, uses
direct ACh agonist, stims muscarinic rec in airway, test for asthma
Neostigmine: type, effect, uses
anticholinesterase, no CNS, post op/neuro ilius and urinary retention, Myasthenia gravis, reversal of NMJ blockade
pyridostigmine: type, effect, uses
Acetylcholinesterase inhibitor, just better neostimine that last longer, Myasthenia gravis, again no CNS
Edrophonium: type, effect, uses
anticholinesterase, short acting used to test for myasthenia gravis
Physostigmine: type, effect, uses
anticholinesterase which crosses into CNS, treat atropine overdose
Donepezil: type, effect, uses
Anticholinesterase, Alzheimers
insecticide/organophosphate poisoning
inhibit irreversibly AChE DUMBBELSS: Diarrhea, Urination, Miosis, Bronchospasm, Bradycardia, Excitation of skeletal muscles/cns, Lacrimation, Sweating, Salivation
treatment of organophophate poisoning

Benzotropine: type, effect, uses
muscarinic antagonist, CNS, parkinsons (park my benz)
Scopolamine: type, effect, uses
muscarinic antagonist, CNS, motion sickness
Ipratropium/tiotriopium: type, effect, uses
muscarinic antagonist, resp, COPD/asthma
oxybutynin: type, effect, uses
muscarnic antagonist, genitourinary, reduce urgency in cystitis and bladder spasms
glycopyrrolate: type, effect, uses
GI, resp, pre-op airway (reduce secretions), oral (drooling/peptic ulcers)
Atropine mech and typical uses
THE muscarinic antagonist, treat bradycardia and opthalmic applications
Atropine effects on eye, airway, stomach, gut, bladder
eye: increase pupil dilation, cycloplegia
airway: decrease secetions
stomach: decrease acid
gut: decrease motility
bladder: decrease urgency in cystitis
Atropine toxicity

glaucoma (old), urinary retention (BPH), hyperthermia (infants)
Epi: receps, app
strong alpha and beta, anaphylaxis, glaucoma, asthma, hypotension
alpha1
sympathetic, vasconstrict, dilate pupil, contract sphincters
alpha2
sympathetic, decrease insulin/lipolysis, increase plate agg
beta1
sympathetic, increase heart rate/contractility/renin/lipolysis
