Answer

Diuretics, Other

Diuretics should be used to manage congestive heart failure secondary to congenital heart defects.

Furosemide (Lasix)

Furosemide increases excretion of water by interfering with the chloride-binding cotransport system, which, in turn, inhibits sodium and chloride reabsorption in the ascending loop of Henle and distal renal tubule. The bioavailability of oral furosemide is 50%. If a switch is made from intravenous to oral administration, an equivalent oral dose should be used. Doses vary depending on the patient's clinical condition.

Hydrochlorothiazide (Microzide)

Hydrochlorothiazide inhibits reabsorption of sodium in distal tubules, causing increased excretion of sodium and water as well as potassium and hydrogen ions.

Metolazone (Zaroxolyn)

Metolazone is a quinazoline diuretic with properties similar to those of thiazide diuretics. It inhibits sodium resorption at the cortical diluting site and the proximal convoluted tubule.
