Mechanism of action

Metolazone is a thiazide-like diuretic that inhibits sodium chloride reabsorption in the distal convoluted tubule, while furosemide is a loop diuretic that blocks the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle. When used concurrently, they produce a synergistic diuretic effect that is more potent than either agent alone, particularly useful in patients with severe fluid overload or diuretic resistance.
