Mechanism of action

By blocking the Na-K-2Cl cotransporter (NKCC2), loop diuretics prevent the reabsorption of sodium, potassium, and chloride in the thick ascending limb, the segment of the nephron responsible for the greatest proportion of electrolyte reabsorption. This leads to increased urinary excretion of sodium, chloride, water, and potassium, resulting in significant diuresis and reduction in blood volume and blood pressure. Loop diuretics are the most potent class of diuretics available.
