Pharmacology Flashcards
Mannitol MOA
osmotic diuretic at PROXIMAL CONV. TUBULE
inc tubular osmolarity –> inc. urine flow, dec intracranial/intraocular pressure
Mannitol use
drug OD, elevated intracranial/intraocular pressure
Mannitol ADR
pulmonary edema, dehydration
Mannitol contraindication
anuria, HF
Acetazolamide MOA
carbonic anhydrase inhibitor at PROXIMAL CONV. TUBULE
causes self-limited NaHCO3 diuresis and dec total body bicarb stores
Acetazolamide use
glaucoma, urinary alkalization, metabolic alkalosis, altitude sickness, pseudotumor cerebri
Acetazolamide ADR
proximal renal tubular acidosis, paresthesia, NH3 toxicity, sulfa allergy
Loop diuretics list
furosemide, bumetanide, torsemide
furosemide, etc use
edematous states, HTN, hypercalcemia
furosemide, etc ADR
Ototoxicity, hypokalemia, dehydration, sulfa allergy, metabolic alkalosis, interstitial nephritis, gout
furosemide, etc. MOA
sulfonamide loop diuretics
inhibit cotransport system of thick ascending limb
abolish hypertonicity of medulla, preventing concentration of urine
Stimulate PGE release (vasodilatory effect on afferent arteriole)
furosemide inhibitor
NSAIDS
what electrolyte does furosemide, etc cause to be lost?
calcium
Ethacrynic acid MOA
nonsulfonamide inhibitor of cotransport system of thick ascending limb
ethacrynic acid use
diuresis in patients allergic to sulfa drugs
ethacrynic acid ADR
very ototoxic
