Answers With Verified Solutions 100%
Correct Latest Update.
What are the neurotransmitters of the PNS - ANSWER
Acetylcholine (mediates cholinergic receptors)
Norepinephrine/epinephrine (mediate adrenergic receptors)
Cholinergic receptor subtypes - ANSWER nicotinic and
muscarinic
Adrenergic receptor subtypes - ANSWER alpha 1, alpha 2, beta 1,
beta 2
Alpha 1 receptor functions - ANSWER vasoconstriction
ejaculation
contraction of bladder neck & prostate
Alpha 2 receptor function - ANSWER little clinical significance
Beta 1 receptor functions - ANSWER Heart (increase rate and
force of contraction)
Kidney (renin release)
Conduction of the AV node
Beta 2 receptor functions - ANSWER Bronchial dilation
relaxation of uterine muscle
vasodilation
glycogenolysis
Dopamine function - ANSWER dilates renal blood vessels
Without subtypes - ANSWER a drug that acts on one site will
alter all sites
Cholinergic drugs function to - ANSWER Turn on PNS
Muscarinic Agonists function - ANSWER mimic the effects of
acetylcholine at muscarinic receptors
,Bethanechol function - ANSWER constricts bronchi, increase GI
tone and motility, contraction of detrusor muscle and relaxes trigone and
sphincter
Bethanechol used for - ANSWER urinary retention
bethanechol adverse effects - ANSWER hypotension, abd
cramps/diarrhea, increased salivation, asthma exacerbation
Cevimeline - ANSWER treats dry mouth in Sjogren Syndrome
Pilocarpine - ANSWER topical therapy for glaucoma
Acetylcholine - ANSWER Used for mitosis (pupil constriction)
after cataract surgery
Muscarinic poisoning treated with - ANSWER atropine
Drugs that turn off PNS - ANSWER Muscarinic antagonists
(parasympatholytic drugs, antimuscarinic drugs, muscarinic blockers,
anticholinergic drugs)
Muscarinic antagonists function - ANSWER selectively block the
effects acetylcholine at muscarinic receptors
Muscarinic antagonists are also known as - ANSWER
parasympatholytic drugs, antimuscarinic drugs, muscarinic blockers or
anticholinergic drugs
Atropine function - ANSWER Increases HR
Decrease secretions
relax bronchi
decrease tone of detrusor
decrease tone & motility of GI
mydriasis (pupil dilation)
Atropine uses - ANSWER preanesthetic
eye disorders
bradycardia
intestinal hypermotility
asthma
muscarinic agonist poisoning
Atropine side effects - ANSWER dry mouth
, blurred vision
increase IOP
urinary retention
constipation
tachycardia
asthma
Atropine can me used to treat _______ but can also worse _______ by
thickening and drying bronchial secretions causing plugging -
ANSWER Asthma
Anticholinergic drugs for overactive bladder - ANSWER
oxybutynin (Ditropan)
Darifenacin
Solifenacin
Tolterodine
Fesorterodine
Trospium
Oxybutynin (Ditropan) - ANSWER anticholinergic side effects
Darifenacin - ANSWER greatest M3 selectivity
can reduce OAB symptoms while having no effects of M1 receptors in brain
or M2 receptors in the heart
Darifenacin can cause - ANSWER dry mouth and constipation
Solifenacin - ANSWER similar to darifenacin but can cause
prolonged QT at high doses
Tolterodine - ANSWER nonselevtive
fewer anticholinergic effects
prolongs QT
Fesoterodine & Trospium - ANSWER nonselective
Scopolamine - ANSWER Muscarinic Antagonist
used for motion sickness
Ipratropium bromide - ANSWER used to treat asthma, COPD and
rhinits
