Flashcards in Duiretics Deck (20):
1

which diuretics cause potassium loss (2)

thiazide like and loop
(greater risk with thiazide)

2

potassium loss caused by diuretics is a particular problem in patients also taking

cardiac glycocisdes (and those with CVD)

3

why is hypokalaemia caused by diuretics a particuluar problem in liver disease

may percipitate encephalopathy

4

what is in co-amilozide

amiloride (k sparing)
and
hydrocholthiazide (thiazide like)

5

which thiazide like diuretics are now preferred for treatment of hypertension

indapamide
chlortalidone (may be given on alt days to control odema)

6

what conditions might be exacerbated by loop diuretics (3)

diabetes (but hypergylcaemia is more likely with thiazide like)
gout
urinary retention in enlarged prostate

7

what class is furosemide

loop

8

what class is bumetanide

loop

9

what class is indapmide

thiazide like

10

how long do duitretic actions of bumetanide and furosemide last

up to 6 hours - so can be BD

11

what class is amiloride

K sparing

12

K sparing diuretics must not be given with

k supplements
(neither should aldosterone antagonists)

13

what class is spironolactone

aldosterone antagonists (which means it is also K sparing)

14

what are first and second line diuretics to be used in cirrhosis of the liver

spironolactone and then furosemide

15

what class is manitol

osmotic - used for cerbral oedema and raised intraoccular pressure

16

acetazolamide is what type of drug..

carbonic anhydrase inhibitor (used for altitude sickness) - weak diuretic effect

17

what are the affects of thiazide like diuretics on elctrolytes and uric acid and glucose

all do down except calcium goes up

uric acid and glucose go up

18

what are the affects of loop diuretics on elctrolytes and uric acid and glucose

all do down
uric acid and glucose (not as much as thiazides) go up

19

what are the affects of K sparinge diuretics on elctrolytes (1)

k goes up

20

what are the affects of aldosterone antagonists diuretics on elctrolytes (3)

k goes up
na goes down
uric acid goes up
