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 leads to increased urine output and reduced fluid volume in the body, lowering blood pressure and reducing edema. It is one of the most potent diuretics available and is commonly used in conditions requiring rapid fluid removal.
