Our ranking reflects each drug’s FDA recall-safety record — not clinical effectiveness for heart failure; the right choice depends on your situation, so confirm it with your prescriber.
How loop diuretic work
Loop diuretics such as furosemide block a salt-transport protein (the Na-K-2Cl cotransporter) in a part of the kidney called the loop of Henle. This stops sodium and chloride from being reabsorbed, so the body flushes out extra salt and water, relieving fluid buildup and swelling.
