Q

what is the pharmacodynamics for furosemide

A

furosemide is a potent diuretic that acts on the kidneys to increase water loss from body to increase the excretion of sodium and water by the kidneys

furosemide inhibits the kidney’s reabsorption from the proximal and distal tubules and the loop of henle.

This works by acting directly on the cells of the nephron and indirectly modifies the content of the renal filtrate
