Endothelin

Released from damaged cells to cause vasoconstriction

1

Gleevac

Tyrosine-kinase inhibitor

2

Angiotensin

Potent vasoconstrictor
Produces aldosterone, which causes reabsorption of Na+ and H2O

3

Vasopresin

ADH... Very potent vasoconstrictor

4

Spironolactone

Blocks the effect of aldosterone
Pee out Na+ instead of reabsorbing it

5

ACE inhibitors

Block the converting enzyme that converts angiotensin to angiotensin 2
Prevents angiotensin 2 from vasoconstricting

6

ARBs/sartans

Angiotensin receptor blocker
Used to treat HTN in ppl intolerant to ACE inhibitors

7

-prils

ACE inhibitors
Side effect of non-productive cough due to incomplete breakdown of bradykinin

8

Bradykinin

Causes arteriole dilation
Increases capillary permeability

9

Which vasodilator would you interfere with to treat migraines?

Serotonin

10

Sildenafil citrate

Viagra
Phosphodiesterase 5 inhibitor
Prevents the breakdown of cGMP
Arterioles in genitalia stay open and relaxed

11

Atropine

Anti-cholinergic drug given before surgery to decrease mucus secretions so patient does not aspirate

12

Adenosine

Released to dilate arterioles in metabolically active tissue to allow for increased blood flow

13

Nitro

A short acting treatment for chest pain that induces vasodilation to decrease venous return and decrease afterload

14

Indomethicine

Prostaglandin inhibitor used to close ductus arteriosus by inducing vasoconstriction

15

Hydrathorathyzine (HTZ)

A diuretic used to treat HTN by decreasing blood volume, decrease venous return, decrease cardiac output, decrease MAP

16

Beta blockers

Block the beta receptors in the heart to prevent Epi and NE from binding... Decrease HR and contractility to decrease cardiac output and decrease MAP

17

Alpha 1 blockers

Affect TPR
Prevent NE from binding to alpha 1 receptors in blood vessels
Vasodilator by increasing the radius
