furesomide (Lasix) What is the class of medicine of:
loop diuretics
furesomide (Lasix)
what is it used for
HTN
furesomide (Lasix)
MOA?
acts on ascending loop of Henle by inhibiting reabsorption of Na, K, Cl which prevents reabsorption of water
furesomide (Lasix)
AEs?
dehydration, hypocalcemia, hyponatremia, hypokalaemia, ototoxicity, hyperglycaemia, increased LDL
hydrochlorothiazide (HCTZ) class of medicine?
thiazide diuretics
hydrochlorothiazide (HCTZ)
used for?
HTN
hydrochlorothiazide (HCTZ)
MOA?
acts on early part of convoluted tubule by inhibiting mechanism that favour Na reabsorption resulting in Na and K excretion and Ca reabsorption (so decrease water reabsorption)
hydrochlorothiazide (HCTZ)
AE?
hypercalcemia, significant loss of K
other similar to loop diuretic
spironolactone
class ?
potassium sparing diuretic
spironolactone
Use
HTP
spironolactone
MOA
limit reabsorption of Na and excretion of K
limit osmotic gradient which drives reabsorption go H2O from late distal convoluted tubule
spironolactone
Ae?
hyperkalemia, nausea, lethargy, mental confusion

calcium channel blockers - dihydropyridine
amlodipine
MOA
block Ca entrance into vascular smooth muscle = vasodilation
amlodipine
