Furosemide is a potent diuretic, with rapid

The half life of Furosemide is up to about 2 hours.
Furosemide inhibits the reabsorption of electrolytes in the
ascending limb of the loop of Henle and also in the distal
tubules. It may also have a direct effect on the proximal
tubules.
Furosemide increase the excretion of sodium, potassium, calcium
and chloride ions and enhances water excretion.
Furosemide has no clinically effect on carbonic anhydrase
enzyme.
