Mech: Inhibits the CA enzyme in prox tubule cells inhibits bicarb reabsorption

Metab: Oral absorption & topical admin -> effects for a few days -> renal excretion

Uses: glaucoma; urinary alkanization; metabolic alkalosis; acute mtn sickness

Toxic: hyperCl- metabolic acidosis; renal stones; renal K+ wasting

C/I: hepatic cirrhosis
Furosemide
Mech: Inhibit Na+ transport in thick limb of loop of Henle

Metab: Oral & parenteral admin.; renal excretion

Uses: CHF/edema; hyperCa++; hyperK+; acute renal failure

Toxic: hypoK+ metabolic alkalosis; ototoxicity; hyperuricemia; hypoMg++, allergenic; excess Na+/H2O loss
Hydrochlorothiazide
Mech: Inhibit Na+ reabsorb in distal convoluted tubule

Metab: Oral absorb; diffs in potency & PHK indapamide; liver metabolism

Uses: HTN; CHF; nephrolithiasis; nephrogenic diabetes insipidus

Toxic: hypoK+ metabolic alkalosis; impaired carbohydrate tolerance; hyerlipidemia; hypoNa+; allergenic
Amiloride (K+ sparing)

Spironolactone (Aldosterone antagonists)
Mech: Amiloride inhibits Na+ flux in collecting tubules; Spiro inhibits aldosterone receptors

Metab: oral admin; some liver metab; renal excretion

Uses: excess mineralcorticoid; CHF; nephrotic syndrome; cirrhosis w/ other drugs (HCTZ); low diuretic ceiling

Toxic: hyperK+; hyperCl- metabolic acidosis; acute renal failure; kidney stones; Spiro -> gynecomastia

C/I: hyperK+

Mech: H2O retention in proximal tubule & descending limb of Henle

Metab: IV admin; glomerular filtration

Uses: incr. urine volume; reduce ICP; reduce IOP
