Low-dose furosemide

Larissa University Hospital · FDA-approved active Small molecule

Low-dose furosemide inhibits the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, reducing sodium reabsorption and promoting diuresis.

Low-dose furosemide inhibits the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, reducing sodium reabsorption and promoting urinary sodium and water excretion. Used for Edema associated with congestive heart failure, Edema associated with hepatic cirrhosis, Edema associated with renal disease.

Mechanism of action

Furosemide is a loop diuretic that blocks the Na-K-2Cl symporter on the apical membrane of thick ascending limb cells, preventing reabsorption of approximately 20-30% of filtered sodium and chloride. This increases urine output and reduces fluid volume, lowering blood pressure and reducing edema. At low doses, the diuretic effect is modest while maintaining better electrolyte balance than standard doses.
