Answer

Diuretics, Loop

These agents relieve peripheral and pulmonary congestion. They promote excretion of water and electrolytes by the kidneys and are used to treat heart failure or hepatic, renal, or pulmonary disease when sodium and water retention has resulted in edema or ascites.

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 IV to oral administration, an equivalent oral dose should be used. Doses vary depending on the patient's clinical condition.

Patients with evidence of heart failure require diuretic therapy. As these patients are preload dependent, such a therapy should be judiciously used to avoid hypotension and depletion of intravascular volume.
