Mannitol is a diuretic that helps your body to produce more urine, reduce swelling and reduce pressure inside the eye. It is an osmotic diuretic that is metabolically inert in humans. This natural substance occurs as a sugar or sugar alcohol in fruits and vegetables. It mainly elevates blood plasma osmolality, resulting in an enhanced flow of water from tissues.
Mannitol, USP, also referred to as D-mannitol, is a white crystalline powder or free-flowing granules freely soluble in water. It is sterile and a nonpyrogenic solution and contains no antimicrobial agents.
