What is the site of action of Furosemide?
Mechanism of action Furosemide, like other loop diuretics, acts by inhibiting the luminal Na-K-Cl cotransporter in the thick ascending limb of the loop of Henle, by binding to the chloride transport channel, thus causing more sodium, chloride, and potassium to stay in the urine.
Which is the site of action for Furosemide as diuretic?
Furosemide is a potent loop diuretic that works to increase the excretion of Na+ and water by the kidneys by inhibiting their reabsorption from the proximal and distal tubules, as well as the loop of Henle. It works directly acts on the cells of the nephron and indirectly modifies the content of the renal filtrate.
What are the sites and mechanism of action of different diuretics?
They act by diminishing sodium reabsorption at different sites in the nephron, thereby increasing urinary sodium and water losses. A second class of diuretics, sometimes termed aquaretics, instead inhibit water reabsorption by blocking vasopressin receptors along the connecting tubule and collecting duct.
