Q

eplerenone

A

aldosterone antagonist - K sparing

21
Q

triamterene

A

Na channel blocker - K sparing

22
Q

amiloride

A

Na channel blocker - K sparing

23
Q

K sparing MOA

A

aldosterone antagonist in collecting tubule

or as Na channel blocker collecting tubule

24
Q

K sparing clinical use

A

hyperaldosteronism
K depletion
heart failure

25
Q

adverse K sparing

A

hyperK - arrhythmia

endocrine effect - spironolactone - gynecomastia, antiandrogen effects

26
Q

diuretics

A
acetazolaminde
mannitol
loops
thiazides
K sparing
27
Q

acid base with CAIs

A

acidemia

-decreased bicarb reabsorption

28
Q

acid base with K sparing

A

acidemia
-aldosteorne block - prevent K secretion and H secretion

also - hyperK leads to K entering all cells in exchange for H

29
Q

acid base with loops

A

alkalemia - volume contraction
-increased angiotensin II - more Na/H exchange PCT > more bicarb reabsorption (contraction alkalosis)

K loss - leads to K exiting cells exchange for H entering cell

low K state - H exchanged for Na in cortical collecting tubule

30
Q

acid base with thiazides

A

alkalemia - volume contraction
-increased angiotensin II - more Na/H exchange PCT > more bicarb reabsorption (contraction alkalosis)

K loss - leads to K exiting cells exchange for H entering cell

low K state - H exchanged for Na in cortical collecting tubule

31
Q

urine Ca with loops

A

decreased paracellular Ca reabsorption

increased urine Ca

32
Q

urine Ca with thiazides

A

enhanced Ca reabsorption - DCT

decreased urine Ca

33
Q

urine potassium

A

increased with loops

34
Q

captopril

A

ACE inhibitor

35
Q

ramipril

A

ACE inhibitor

36
Q

ACE inhibitor mechanism

A

inhibit ACE

  • decreased ANG II > decreased GFR
  • decreased constriction efferent arterioles

renin increase - loss of feedback

also prevent inactivation of bradykinin

37
Q

ACE inhibitor clinical use

A

HTN, HF, proteinuria

diabetic nephropathy

prevent unfavorable heart remodeling

38
Q

adverse ACE inhibitor

A
cough
angioedema - lots of bradykinin
teratogen
creatinine increase
hyperKa
hypotension
39
Q

avoid in B/L renal artery stenosis

A

ACE inhibitor - because will further decrease GFR > renal failure

40
Q

losartan

A

ANG II blocker

41
Q

candesartan

A

ANG II blocker

42
Q

valsartan

A

ANG II blocker

43
Q

ANG II blocker MOA

A

block ANG II binding AT1 receptor

44
Q

clinical use ANG II blocker

A

HTN
HF
proteinuria
diabetic nephropathy

45
Q

adverse ANG II blocker

A

hyperK
decreased renal function
hypotension
teratogen

46
Q

aliskiren

A

direct renin inhibitor

block conversion angiotensinogen to ANG I

47
Q

clincal use aliskiren

A

HTN

48
Q

adverse aliskiren

A

hyperK
decreased renal f unction
hypotension

CI - diabetic taking ACE I or ARBs
