Diuretics Flashcards
Diuretic
= agent that increases rate of urine flow
Most via increased Na excretion
Acetazolamide
CAI
MOA: decrease H secretion = decrease Na reabsorption = increase Na excretion
Furosemide, Bumetanide
Loop Diuretics
MOA: inhibit NKCC2 in TAL = decrease Na reabsorption = increase Na excretion
Hydrochlorothiazide, Chlorothiazide
Thiazide Diuretics
MOA: inhibit NCC in DCT = decrease Na reabsorption = increase Na excretion
Amiloride, Triamterene, Spironolactone
K-sparing Diuretics
MOA: block ENaC
Spirono/Eplerenone: inhibit ald. binding to MR = decrease stimulation of ENaC
= all decrease Na reabsorption in CNT/CD
Increased Na reabsorption =
Increased K secretion
Effects of Diuretics on K
CAI/LD/TZ = Hypokalemia
K-sparing = Hyperkalemia
Effects of Diuretics on H/HCO3
LD/TZ = Metabolic Alkalosis
CAI/K-sparing = Metabolic Acidosis
Effects of Diuretics on Ca
TZ = Hypercalcemia
LD = Hypocalcemia
Effects of Diuretics on Mg
LD/TZ = Hypomagnesemia
Effects of Diuretics on Uric Acid
LD/TZ = Hyperuricemia
