Mechanism of action

Furosemide blocks the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, preventing reabsorption of sodium, potassium, and chloride. This increases osmotic pressure in the tubular lumen, drawing water into the urine and producing rapid diuresis. The drug is highly potent and commonly used to reduce fluid overload in cardiac and renal conditions.
