Flashcards in Review III Deck (43):
1

tyramine

inhibited by cocaine

needs NET to get into cell to cause its effect

increases NE release, bc displaces from vesicle

2

low dose epinephrine

beta2 vasodilation

at high dose - alpha1 vasoconstriction with reflex bradycardia

3

norepinephrine

no beta2

increased mean pressure and TPR
-reflex bradycardia

4

epinephrine

alpha 2

5

isoproterenol

beta-selective

6

phenylephrine

alpha1 agonist

vasoconstriction with reflex bradycardia

7

fendolopam

D1 agonist

8

dobutmine

beta1 agonist

9

cardiogenic shock

dobutamine - beta1 agonist

10

dopamine

beta1 and D1 agonist

11

nasal decongestant

phenylephrine - alpha1 agonist

12

methoxamine

alpha1 agonist
-similar to phenylephrine

13

albuterol

beta2 agonist

14

salmeterol

beta2 agonist - long duration

15

formoterol

beta2 agonist - long duration

16

dexedrine

amphetamine

17

amphetamine intoxication

weak bases, so acidify urine to excrete it

18

ephedrine

beta agonist and increased NE release

19

platelet aggregation

alpha2

20

phentolamine

alpha antagonist
reversible

-vasodilation - reflex tachycardia

21

phenoxybenzamine

alpha antagonist
irreversible
alpha1 > alpha2

-Tx for pheochromocytoma

22

pheochromocytoma

phentolamine or phenoxybenzamine Tx

23

prazosin

alpha1 antagonist

less reflex tachycardia

24

tamulosin

alpha1A antagonist

Tx for BPH

25

benign prostatic hypertrophy

tamulosin

26

propanolol

beta antagonist
lipid soluble - may cause drowsiness

27

stage fright

propanolol

28

metoprolol

beta1 antagonist

29

atenolol

beta1 antagonist

30

labetalol

alpha1 and beta antagonist

31

timolol

beta antagonist

high potency

32

nadolol

beta antagonist

long duration

33

esmolol

beta1 antagonist

rapid onset

34

Tx for pheochromocytoma

phenoxybenzamine and beta blocker

35

reduce mortality in CHF

carvedilol

beta and alpha1 antagonist

36

reserpine

blocks NE

blocks vesicular transporter

37

guanethidine

displacement and release of NE
-blocks NE release

38

bretylium

antiarrhythmic

blocks NE release

39

guanadrel

rapid onset, short duration, less side effects

like guanethidine

40

clonidine

alpha2 agonist
-sudden withdrawal - hypertensive crisis

41

methyldopa

central alpha2 agonist
-false neurotransmitter

HTN in pregnant floozies

42

HTN in pregnant floozies

methyldopa

43

guanabenz

central alpha2 agonist
