Q

How do ACE-I work?

A

16
Q

What is the initial drug choice for HTN pt with BM & CKD

A

ACE-I: help preserve kidney function

17
Q

What pt population will benefit from ACE-I use?

A

Mild-Mod HTN
Younger whites
Use when diuretics are insufficient
Reduce mortality in PT with MI and heart failure

18
Q

How do ARBs work?

A

Block the interaction of angiotensin II on receptors

19
Q

What pt population with benefit from ARBs?

A

Pt with DM or CKD because they help preserve kindly function

Do not increase bradykinin = no cough

20
Q

What are other agents available to treat refractory HTN or other special cases?

A

Aldosterone receptor antagonists: combo with BB and ARBs after MI with heart failure

Alpha-blockers: BPH
Central Sympatholytics
Vasodilators
Aliskiren: renin inhibitor

21
Q

How do Calcium Channel Blockers works?

A

Peripheral vasodilation

22
