Is Mannitol a loop diuretic?

Mannitol is classified as an osmotic diuretic, not a loop diuretic. Loop diuretics, such as furosemide, work by inhibiting sodium reabsorption in the ascending loop of Henle in the kidneys. They are commonly used to manage conditions such as congestive heart failure and edema due to their potent diuretic effect.

Mannitol, on the other hand, acts primarily by increasing the osmolarity of the filtrate in the renal tubule, thus inhibiting water reabsorption. This results in increased urine output by osmotically forcing water into the urine, which is different from the mechanism of action of loop diuretics. Mannitol is often used in situations such as reducing intracranial pressure or treating acute kidney injury but does not share the same mechanism of action as loop diuretics.

Therefore, the statement that Mannitol is a loop diuretic is false.
