Aridol Kit (Mannitol)
Osmotic diuretic that elevates glomerular filtrate osmolarity to inhibit tubular water reabsorption.
Mannitol (OSMITROL) is an osmotic diuretic indicated for reducing intracranial pressure, cerebral edema, and elevated intraocular pressure through osmotic mechanisms. It distributes to extracellular space within 20-40 minutes with a half-life of 0.5-2.5 hours in normal renal function, primarily eliminated unchanged via renal filtration. Major risks include renal failure with nephrotoxic drugs or concurrent diuretics, CNS toxicity with neurotoxic agents, and cardiac complications from electrolyte imbalances. Contraindications include anuria, severe hypovolemia, pulmonary edema, and active intracranial bleeding except during craniotomy.

Mechanism of action
Mannitol is a small molecular weight solute confined largely to the extracellular space. When administered intravenously, it elevates the osmolarity of the glomerular filtrate, which hinders tubular reabsorption of water and enhances excretion of sodium and chloride. The increase in extracellular osmolarity induced by mannitol causes movement of intracellular water to extracellular and vascular spaces, thereby reducing intracranial pressure, cerebral edema, and intraocular pressure.
