| Term | Definition |
|---|---|
| MOA: Furosemide | Loop Diuretic: Acts on ascending loop of Henle to block sodium and chloride reabsorbtion |
| Therapeutic Uses: Furosemide | Pulmonary Edema associated with CHF, used when CHF edema not responsive to less powerful diuretics. **Can promote diuresis even with severe renal impairment |
| Adverse Effects: Furosemide | Dehydration, hypokalemia, hypotension, ototoxicity |
| Medications in class: Loop Diuretics | Furosemide, bumetanide, torsemide |
| MOA: Hyrdochlorothiazide | Thiazide Diuretic: Acts on early segment of distal convoluted tubule; increases secretion of sodium and water |
| Therapeutic uses: Hydrochlorothiazide | Essential HTN, Edema related to CHF |
| Adverse Effects: Hydrochlorothiazide | Dehydration, hypokalemia, hypotension |
| MOA: Spironolactone | Potassium Sparing Diuretic: Blocks the action of aldosterone in distal nephron, leading to potassium retention, sodium excretion |
| Therapeutic Uses: Sprionolactone | HTN, Edema, CHF |
| Adverse Effects: Sprionolactone | Hyperkalemia, endocrine effects |
| What class is Triamterene? How does it differ from the other mediation in this class? | Potassium Sparing Diuretic; Significantly faster onset than spironolactone (2-4hr vs. 24-48hr). |
