Description
|
A benzoic-sulfonamide-furan. It is a diuretic with fast onset and short duration that is used for edema and chronic renal insufficiency. [PubChem] |
Indication |
For the treatment of edema associated with congestive heart failure, cirrhosis of the liver, and renal disease, including the nephrotic syndrome. Also for the treatment of hypertension alone or in combination with other antihypertensive agents. |
Pharmacology |
Furosemide, a sulfonamide-type loop diuretic structurally related to bumetanide, is used to manage hypertension and edema associated with congestive heart failure, cirrhosis, and renal disease, including the nephrotic syndrome. |
Toxicity |
Profound diuresis may cause fluid and electrolyte depletion. Excessive dehydration and potassium depletion may occur. Excessive diuresis may cause rapid weight loss, orthostatic hypotension or acute hypotensive episodes. May also cause tinnitus, reversible or permanent hearing loss or reversible deafness. |
Affected Organisms |
• |
Humans and other mammals |
|
Biotransformation |
Only a small amount is hepatically metabolized to the defurfurylated derivative, 4-chloro-5-sulfamoylanthranilic acid. |
Absorption |
60% absorbed in patients with normal renal function |
Half Life |
2 hours |
Protein Binding |
95% bound to plasma proteins |
Elimination |
Furosemide is excreted in urine. Significantly more furosemide is excreted in urine following the I.V. injection than after the tablet or oral solution. |
