Furosemide aka Lasix is probably the most commonly used diuretic. It is used to reduce body water content (usually by inducing urination) for two conditions: hypertension or edema. It is the #1 treatment for edema associated with congestive heart failure (aka left-sided) but is also used for patients with cirrhosis or renal impairment. #pharmacology
Furosemide is a loop diuretic causing fast and quick diuresis. It possesses natriuretic impact and additionally decreases degrees of Cl- in blood, increases excretion of k+, Ca2+, Mg2+. Penetrating right into a renal tubule in ascending thick limb of Henle's loop it blocks re-absorption of Na+ and Cl-. due to accelerated excretion of Na+ secondary intensified excretion of water occurs and as well as multiplied secretion of ok+ in distal a part of the renal tubule.
