Q

what are the key takeaways of ALLHAT trial?

A

thiazide diuretics should be first line
for pts who cannot take diuretic –> prescribe a CCB or ACEi

25
what HTN drugs are thiazides?
chlorothalidone hydrochlorothalidone indapamide metolazone
26
what classes of diuretics are used in HTN?
thiazide loop aldosterone antagonists potassium-sparing
27
what loop diuretics are used in HTN?
furosemide torsemide bumetanide
28
what aldosterone antagonists are used in HTN?
spironolactone eplerenone
29
what potassium-sparing diuretics are used in HTN?
amiloride triamterene
30
what happens after initially introducing diuretics?
diuresis --> reduced stroke volume --> increased PVR
31
what happens long-term after introducing diuretics?
stroke volume returns to normal and decreases the PVR to go below pre-treatment levels
32
what is the most potent thiazide diuretic?
chlorothalidone
33
what are the clinical pearls of thiazides?
more effective than loops with CrCl over 30 mL/min dose in the morning to avoid nocturnal diuresis
34
how often should thiazides be taken?
once a day
35
what are the SE of thiazides?
low K low Mg high Ca hyperuricemia hyperglycemia hyperlipidemia sexual dysfunction increase in TG/cholesterol
36
what drug-drug interaction is important to note in thiazides?
lithium --> causes toxicity with concurrent use
37
what is the CI of thiazides?
sulfa allergy anuria
38
what is the indication of loop diuretics?
heart failure not first line for HTN but more effective than thiazides when CrCl is under 30 mL/min
39
what are the clinical pearls of loop diuretics?
dose in the morning/afternoon to avoid nocturnal diuresis high-ceiling dose response curve (may need higher doses in severely reduced renal function or fluid overload --> switching to another loop or from oral to IV can help)
40
how often should loop diuretics be taken?
1-2x daily QD for torsemide
41
what is SE of loop diuretics?
low K low Mg low Ca hyperuricemia ototoxicity
42
what is CI of loop diuretics?
sulfa allergy
43
what is the preferred add-on agent in resistant HTN?
spironolactone
44
what are the clinical pearls of aldosterone antagonists?
dose in the morning/afternoon to avoid nocturnal diuresis don't use if potassium is greater than 5 mEq/L
45
what should be done if the pt develops gynecomastia?
switch from spironolactone to eplerenone
46
what is another name for aldosterone antagonists?
mineralocorticoid receptor antagonists
47
how often should aldosterone antagonists be dosed?
1-2x per day
48
under what conditions should an aldosterone antagonist be held or reduced?
if potassium is greater than 5/5 mEq/L or SCr increases by over 25%
49
what is SE of aldosterone antagonists?
high K hyponatremia gynecomastia (spironolactone 10%)
50
what are the drug-drug interactions of aldosterone antagonists?
ACEi ARBs renin inhibitors NSAIDs increase risk of hyperkalemia
51
what are CIs of aldosterone antagonists?
concomitant use of potassium sparing diuretics
52
what are the CIs of eplerenone?
impaired renal function T2DM with proteinuria
53
what are the lab values for impaired renal function?
CrCl under 50 mL or SCr greater than 2 for men or over 1.8 for women
54
what is the purpose of potassium-sparing diuretics in HTN?
used in combination with thiazides to minimize hypokalemia (minimal BP effects)
55
what are the clinical pearls of potassium-sparing diuretics?
use with caution in patients with DM or CKD (GFR under 45) dose in morning to avoid nocturnal diuresis
56
how often should potassium-sparing diuretics be taken?
1-2x daily
57
what is SE of potassium-sparing diuretics?
high K increased uric acid hyperglucemia
58
what are the monitoring parameters of diuretics
electrolytes and renal function at baseline 1-2 weeks after initiation 3-4 months after initiation (loop/aldosterone only) every 5-12 months
59
what are the clinical pearls of diuretics?
nocturnal diuresis thiazides are first-line for most HTN pts spironolactone is first-line for resistant HTN potassium-sparing is not monotherapy pts with sulfa allergy cannot take check CrCl when choosing class monitor potassium and other electrolytes
