How osmotic diuretic work
Osmotic diuretics like mannitol are sugar-like molecules that the kidney filters but cannot reabsorb, so they stay in the urine and pull water along with them like a magnet. This boosts urine output and can also draw excess fluid out of swollen tissues, such as a swollen brain.
These are all Mannitolin different brands or formulations, so we don’t rank them against each other — the list below is for comparing brand vs generic, dose, and typical cost, not for picking a “best” one on effectiveness.
