Flashcards in ANS application Deck (17):
1

tropcamide- pupil reaction

muscarinic antagonist
dilates the pupil in the presence of sympathetic outflow

2

timolol- pupil

beta antagonist
no effect on the pupil

3

pilocarpine- pupil

muscarinic agonist
constriction

4

phenylephrine- pupil

sympathomimetic (alpha agonist)
dilation

5

isoproterenol- cardiac contractility

beta 1 = beta 2 agonist
increased

6

epinephrine-cardiac contractility

sympathomimetic
increased

7

prazosin- cardiac contractility

alpha 1 antagonist
no effect

8

propanolol- cardiac contractility

beta 1 = beta 2 antagonist
decreases
no change if heart is in isolation

would prevent epi/norepi from working (beta blocked)

9

atenolol- cardiac contractility

beta 1 antagonist

decreases
no change if heart is in isolation

10

mid dose dopamine acts as

b1/b2 agonist
can cause central release of NE

11

atropine- cardiac contractility

muscarinic agonist
no effect
would induce bradycardia

12

phenylephrine- bronchiole

alpha 1 agonist
no change

13

albuterol- bronchiole

beta 2 agonist
dilation

14

epinephrine- bronchiole

sympathomimetic
dilation

15

propanolol- bronchiole

beta 1 = beta 2 blocker
constriction

16

metoprolol- bronchiole

beta 1 >> beta 2 antagonist
no change

17

ipratropium- bronchiole

M agonist
constriction
