IV Furosemide and IV Acetazolamide

Rambam Health Care Campus · FDA-approved active Small molecule

This combination uses furosemide (a loop diuretic) to increase urine output and acetazolamide (a carbonic anhydrase inhibitor) to promote bicarbonate and electrolyte excretion, together enhancing diuresis and reducing fluid overload.

Mechanism of action

Furosemide inhibits the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, preventing reabsorption of sodium and chloride and producing potent diuresis. Acetazolamide inhibits carbonic anhydrase in the proximal tubule, reducing bicarbonate reabsorption and promoting sodium and water excretion. Together, they provide synergistic diuretic and natriuretic effects, often used in resistant edema or acute decompensated heart failure.
