decrease
slow

51
Q

Benicar (olmesartan)
Cozaar (losartan)
Diovan (valsartan)
What kind of anti-hypertensive drug?

A

Angiotensin REceptor Blockers (ARBs)

52
Q

How do ARBs work

A

block the action of angiotensin II (a constrictor) –> vasodilation

53

Vasotec (enalapril)
Altace (ramipril)
Zestril (lisinopril)
are what type of drugs

A

Angiotensin- converting enzyme (ACE) inhibitors

54
Q

How do ACE inhibitors work?

A

inhibits the enzyme that converts ang I to ang II so no ang II is made. ACE inhibitors block ACE from breaking down bradykinin
bradykinin vasodilates

ACE is a vaso___
Bradykinin is a vaso___

A

vasoconstrictor
vasodilator
