Diuretics Flashcards
Acetazolamide
Decreases secretion of aqueous increases respiration for metacid.
Used in glaucoma, mountain sickness, edema with alkalosis
Dorzolamide, brinzolamide, dichlorphenamide, methazolamide
Carbonic anhydrase inhibitors
Works on proximal convoluted tubules
Isosmotic reabsorption of AA, GLUC, 60-70% NaCl and NaHCO3
Uric acid transport
ACETAZOLAMIDE
Loop diuretics
Work on thick ascending loop of henle.
NaCl reab through nak2cl transporter.
Calcium and magnesium reabsorption.
NSAIDs decrease efficacy
Furosemide
Bumetanide, Torsemide, ethacrynic acid
Loop diuretic toxicities
OH DANG!!!
Ototoxicity, Hypokalemia, Dehydration, Allergy to sulfa, Nephritis, Gout
Thiazides
Work on distal convoluted tubule.
Calcium absorption under the influence of parathyroid hormone.
Hydrochlorothiazide, chlorthalidone, indapamide, metolazone
Potassium sparing diuretics
Works on cortical collecting duct. Last tubular site of na absorption
Under influence of aldosterone .
Acidification of the urine by ammonium chloride
K sparing drugs
The K STAEs
spirinolactone, triamterene, Amiloride, Epelerenone
Drugs that cause gynecomastia
Some Drugs Create Awesome Knockers
Soirinolactone, Digoxin, Cimetidine, Alcohol, Ketoconazole
Amiloride/triamterene
Na blocker, inhibits ENAC cells in CCD reduces Na absorption and K secretion
Spirinolactone/Epelerenone
Aldosterone antagonist reduces K excretion.
Epelerenone reduces progression of DM nephropathy and reduces postMI mortality
Osmotic diuretics
Remains in lumen and holds in water.
Reduced water reab in descending limb of LOH and collecting tubule
Osmotic diuretic drugs
Mannitol, glycerin, isosorbide, urea.
Used in rhabdomyolysis, hemolysis, increased ICP.
Do not use if with heart failure or pulmonary edema
ADH agonist,
Water reab in medullary collecting duct occurs under control of ADH/Desmopressin
V1V2 ADH receptor agonist. Insertion of aquaporin water channels.
Use in vWd, hemophilia
ADH antagonist
Conivaptan, tolvaptan, lixivaptan, demeclocycline, lithium
Used in SIADH
WOF central pontine myelinolysis
