Flashcards in Exam 2 DRUGS ONLY Deck (22):
1

Alpha 1 receptors

vascular smooth muscle,

skin, kidney, viscera, skeletal

NE binding leads to vasoconstriction

2

Alpha 2 receptors

Presynaptic ganglia

auto inhibition of NE

3

Beta 1 receptors

Heart, Epi/NE

induces contractility, heart rate, velocity

4

Beta 2 receptors

pulmonary airways, skeletal muscle vasculature

auto stim of NE at presynaptic ganglia

VASODILATION

5

Dopamine

Beta agonist- lead to vasodilation

tx acute renal vailure- increase perfusion to kidneys

6

Dobutamine

beta 1

tx congestive heart failure

acts as positive ionotrope

7

Ephedrine

Alpha/Beta agionist

beta lipolysis/thermogenic

Tx urinary incontince/hypotensiono

8

Phenylephrine

alpha agonist

pupillary dilation, hypotension/hypovolemic shock

alpha stim leads to vasoconstriction

9

Albuterol

beta 2 agonist

bronchodialtion

10

CLenbuterol

tx COPD, banned in horses

beta 3 stim/bronchodialtion

11

Terbutaline

long lasting beta 2,

takes longer to take effect

12

Propanolol

beta blocker, not beta 1 specific

risk blocking beta 2, leads to bronchoconstriction

13

Atenelol

beta 1 specific

used for high blood pressure

anti anxiety

14

Phenbenzamine

alpha 1/2 antagonist

decreases urethral sphincter tone, laminitis

leads to vasodialtion of peripheral vessels-> increases peripheral perfusion

15

Phentolamine

alpha 1/2 blocker

save fingers injected w/ epi

also tx pheochromatomas- adrenal gland tumors, reduces effect of too much epi

16

Carbacol

Cholinergic receptor agonist

17

Bethanecol

Muscarinic recptors agonist

used for bladder stimualtion (M3)

18

Pilocarpine

muscarinic receptors agonist

tx keratoconjunctivitis, glaucoma (M3)

causes pupil constriction

19

Edrophonium/Pyridostigme

Tx Myasthenia Gravis

cholinesterase inhibitors- prevent breakdown of Ach

20

atropine

Revers effect of Organophosphates; muscarinic receptor antagonist

21

Tx for hormonal incontinence?

DES- Oral Diethylstillbestrol

Phenylpropanolamine PPA

22

Tx Urge incontinence

Oxybutynin (M3 antagonist)
