16
Q

Adrenergic receptors in the eye

17
Q

Stimulation of a1 causes

A

CONTRACTION

  • splanchnic vasoconstiction
  • Mydriasis (dilate pupil)
  • contraction of bladder sphincter
18
Q

Stimulation of B1 causes

A

increased HR, AV conduction, increased renin secretion from the kidney

19
Q

Stimulation of B2 causes

A

RELAXATION

  • vasodilation of vessels feeding skeletal muscle
  • bronchodilation
  • GI relaxation
  • relaxation of uterine muscle
  • relaxation of bladder
20
Q

a2 stimulation causes

A

decreased GI motility, inhibition of NE release in presynaptic membrane

21
Q

Epinephrine adrenergic receptors

22
Q

Norepinephrine adrenergic receptors

23
Q

Isoproterenol adrenergic receptors

24
Q

Albuterol acts on which adrenergic receptors?

25
Clonidine works on which adrenergic receptors?
a2
26
Dopamine works on which adrenergic receptors?
D1, indirect
27
Prazosin antagnoizes which adrenergic receptors?
a1
28
Doxazosin antagnoizes which adrenergic receptors?
a1
29
Terazosin antagnoizes which adrenergic receptors?
a1
30
The "-zosin"s work on which adrenergic receptors?
a1
31
Metoprolol antagnoizes which adrenergic receptors?
B1
32
Atenolol antagnoizes which adrenergic receptors?
B1
33
What are the "cardiac specific" Beta blockers?
Metoprolol and atenalol because they only antagonize B1, found in the heart

B1, B2
35
Labetalol antagnoizes which adrenergic receptors?
a1, B1, B2
36
Carvedilol antagnoizes which adrenergic receptors?
a1, B1, B2
