Frusemide in left ventricular failure

Frusemide is a loop diuretic.  It is also a pulmonary venodilator.  In left ventricular failure, frusemide is given intravenously.  It causes pulmonary venodilation and relieves pulmonary congestion. Also by increasing urine formation, it decreases blood volume and venous return thus decreasing preload of the heart.
