Cholinergic (PNS) Agonists
Example of drugs
Pilocarpine-Bethanechol [M]
Neostigmine-Pyridostigmine (i)
Edrophonium-Donepezil (i)
Organophosphate nerve gases (i)
Cholinergic (PNS) Agonists
Effect on heart
M = decr heart rate (SA node) M = decr contractility (atria only) M = decr conduction (AV node)
Cholinergic (PNS) Agonists
Effect on blood vessel
M = (vasodilation) [not innerv]
Cholinergic (PNS) Agonists
Effect on Blood pressure
M = decr blood pressure (danger= hypotension)
Cholinergic (PNS) Agonists
Effect on lung
M = bronchoconstriction (incr secretions)
Cholinergic (PNS) Agonists
Effect on eye
M = miosis (constriction) M = accomodation (near vision) M = incr aqueous humor outflow (glaucoma)
Cholinergic (PNS) Agonists
Effect on GI/GU
M = incr salivation (xerostomia) M = incr detrusor contraction (incr urinary flow) M = incr motility (paralytic ileus) (danger = diarrhea)
Cholinergic (PNS) Agonists
Effect on NMJ
NM = muscle contraction (myasthenia gravis)
Cholinergic (PNS) Agonists
Effect on CNS
M = memory/cognition/movement (alzheimer’s disease)
Cholinergic Antagonists (SNS)
Example of drugs
Atropine-scopolamine-benztropine [M]
Oxybutynin-Tolterodine [M]
Ipratropium-Tiotropium [M]
Atracurium-Rocuronium-Succinylcholine [Nm]
Cholinergic AntAgonists (SNS)
Effect on heart
incr heart rate [used in bradycardia]
Cholinergic AntAgonists (SNS)
Effect on blood vessels
no cholinergic tone to antagonize
Cholinergic AntAgonists (SNS)
Effect on blood pressure
minimal
Cholinergic AntAgonists (SNS)
Effect on lung
bronchodilation [asthma] can cause drying
Cholinergic AntAgonists (SNS)
Effect on eyes
mydriasis [eye exams]
can cause blurred vision
decr outflow (incr intraocular pressure) exacerbate glaucoma
