Torsemide vs. Bumex vs. Lasix

January 21, 2023

Demadex (torsemide), Bumex (bumetanide), and Lasix (furosemide) are diuretics. They rid the body of excess fluid by increasing the amount of urinary output. They are given to treat fluid retention in cases of congestive heart failure, liver disease, and kidney disease. Removing excess fluid can treat breathing problems, swollen face, swollen abdomen, and swollen arms and legs. The diuretics can also treat high blood pressure by removing excess fluid in the blood vessels so that the blood pressure comes down and the heart does not have to pump as hard.
