ANS application Flashcards
tropcamide- pupil reaction
muscarinic antagonist
dilates the pupil in the presence of sympathetic outflow
timolol- pupil
beta antagonist
no effect on the pupil
pilocarpine- pupil
muscarinic agonist
constriction
phenylephrine- pupil
sympathomimetic (alpha agonist)
dilation
isoproterenol- cardiac contractility
beta 1 = beta 2 agonist
increased
epinephrine-cardiac contractility
sympathomimetic
increased
prazosin- cardiac contractility
alpha 1 antagonist
no effect
propanolol- cardiac contractility
beta 1 = beta 2 antagonist
decreases
no change if heart is in isolation
would prevent epi/norepi from working (beta blocked)
atenolol- cardiac contractility
beta 1 antagonist
decreases
no change if heart is in isolation
mid dose dopamine acts as
b1/b2 agonist
can cause central release of NE
atropine- cardiac contractility
muscarinic agonist
no effect
would induce bradycardia
phenylephrine- bronchiole
alpha 1 agonist
no change
albuterol- bronchiole
beta 2 agonist
dilation
epinephrine- bronchiole
sympathomimetic
dilation
propanolol- bronchiole
beta 1 = beta 2 blocker
constriction
