Medication Summary
The goals of pharmacotherapy are to reduce morbidity and to prevent complications in patients with ascites.
Diuretics
Class Summary
Diuretic agents are the mainstay of medical therapy in ascites.
Spironolactone (Aldactone)
For the management of edema resulting from excessive aldosterone excretion. Competes with aldosterone for receptor sites in distal renal tubules, increasing water excretion while retaining potassium and hydrogen ions. The peak effect of Aldactone is approximately 3 d.
Furosemide (Lasix)
Increases the excretion of water by interfering with chloride-binding cotransport system, which, in turn, inhibits sodium and chloride reabsorption in the ascending loop of Henle and distal renal tubule. Dose must be individualized to patient.
Depending on the response, administer at increments of 20-40 mg, no sooner than 6-8 h after the previous dose, until the desired diuresis occurs. When treating infants, titrate in increments of 1 mg/kg/dose until a satisfactory effect is achieved.
Amiloride (Midamor)
A pyrazine-carbonyl-guanidine unrelated chemically to other known antikaliuretic or diuretic agents. Potassium-conserving (antikaliuretic) drug which, compared with thiazide diuretics, possesses weak natriuretic, diuretic, and antihypertensive activity.
Metolazone (Mykrox, Zaroxolyn)
Helps treat edema in congestive heart failure. Increases excretion of sodium, water, potassium, and hydrogen ions by inhibiting reabsorption of sodium in distal tubules. May be more effective in those with impaired renal function.
Mannitol (Osmitrol)
Inhibits tubular reabsorption of electrolytes by increasing the osmotic pressure of glomerular filtrate. Increases urinary output.
