tox of mannitol
pulmonary edema, dehydration, contraindicated in anuria and CHF
site of mannitol action
PCT
site of acetazolamide action
PCT
acetazolamide MOA
carbonic anhydrase inhibior. casues NaHCO3 diuresis and reduction of bicarb body stores
use of acetazolamide
glaucoma, urinary alkinization, metabold acidosis, altitide sickness, pseudotumor cerebri
tox of acetazolamide
hyperchloremic metabolic acidosis, paresthesias, NH3 tox, sulfa allergy
loop diuretics
furosemide, ethacrynic acid, HCTZ,
site of furosemide, ethacrynic acid, action
thick ascending loop
MOA of furosemide
inhibits Na/K/2 CL- cotransport system. Stimulates PGE release, increases Ca++ excretion
drug that will counteract furosemide
NSAIDS
uses of furosemide
quick need for fluid loss (CHF, cirrhosis) hypertension, hypercalcimia
tox of fuseromide
ototox, hypokalemia, dehydreation, sulfa allergy, nephritis, gout
use of ethacryinic acid
