Pharmacology Flashcards
Osmotic Diuretic used for drug overdose; to decrease ICP and IOP
Mannitol
C/I of Mannitol
Anuria, CHF
Carbonic anhydrase inhibitor that causes self-limites NaHCO3 diuresis and decreases HCO3-
Acetazolamide
Glaucoma, urinary alkalinization, metabolic alkalosis, altitude sickness, pseudotumor cerebri
Acetazolamide
Toxic effects of Acetazolamide
Hyperchloremic metabolic acidosis, paresthesia, NH3 toxicity, sulfa allergy
Sulfonamide loop diuretic
Furosemide
Inhibits Na/K/2Cl of TAL abolishing hypertonicity of medulla
Furosemide and Ethacrynic acid (loops)
Diuretic that stimulates PGE release (dilates afferent)
Furosemide and Ethacrynic acid (loops)
Diuresis in patients allergic to sulfa drugs
Ethacrynic Acid (Phenoxyacetic acid loop)
Toxicity of Loops
Ototoxicity, hypokalemia, dehydration, allergy (sulfa if furosemide), nephritis (interstitial), gout
MoA of Hydrochlorothiazide
inhibits NaCl reabsorption in early DCT decreasing the diluting capacity of the nephron. Decrease calcium excretion
Clinical Uses of Hydrochlorothiazide
HTN, CHF, idiopathic hypercalciuria, nephrogenic diabetes insipidus, osteoporosis
Toxicity of Hydrochlorothiazides
Hypokalemic metabolic alkalosis, hyponatremia, hyperglycemia, hyperlipidemia, hyperuricemia, and hypercalcemia. sulfa Ax
Potassium Sparing Diuretics - aldosterone receptor antagonists
Spironolactone, eplerenone
Potassium Sparing Diuretics - blocks ENaC
Triamterine, Amiloride
