Mechanism of Action
Furosemide, a loop diuretic, inhibits water reabsorption in the nephron by blocking the sodium-potassium-chloride cotransporter (NKCC2) in the thick ascending limb of the loop of Henle. This is achieved through competitive inhibition at the chloride binding site on the cotransporter, thus preventing the transport of sodium from the lumen of the loop of Henle into the basolateral interstitium. Consequently, the lumen becomes more hypertonic while the interstitium becomes less hypertonic, which in turn diminishes the osmotic gradient for water reabsorption throughout the nephron. Because the thick ascending limb is responsible for 25% of sodium reabsorption in the nephron, furosemide is a very potent diuretic.
- 60% absorbed in patients with normal renal function
- Only a small amount is hepatically metabolized to the defurfurylated derivative, 4-chloro-5-sulfamoylanthranilic acid.
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.
