Study Notes
Diuretics in Heart Failure
- Diuretics are indicated to control edema in Chronic Heart Failure (CHF).
Furosemide
- Furosemide is a loop-diuretic used to treat cardiogenic edema in animals.
- Adverse effects of furosemide include excessive fluid and/or electrolyte losses.
Spironolactone
- Spironolactone is a K+-sparing diuretic used as adjunct therapy for chronic refractory heart failure.
- Spironolactone is contraindicated in hyperkalemic patients.
- Spironolactone may decrease digoxin clearance.
Thiazide Diuretics
- Thiazide diuretics, such as chlorothiazide or hydrochlorothiazide, are occasionally used in combination with furosemide and other therapy for refractory CHF.
