L-Mannitol is widely used in the pharmaceutical industry as an excipient in tablet formulations. It serves as a diluent and sweetening agent, particularly in chewable tablets and oral disintegrating tablets, due to its pleasant taste and mouthfeel. Its non-hygroscopic nature makes it suitable for moisture-sensitive drugs. In medical applications, it is utilized as an osmotic diuretic to reduce intracranial and intraocular pressure, often administered intravenously. Additionally, L-Mannitol is employed in diagnostic procedures, such as renal function tests, to assess kidney filtration rates. In the food industry, it acts as a low-calorie sweetener and texturizing agent in sugar-free products. Its ability to stabilize and protect biological materials also makes it valuable in cryopreservation and as a bulking agent in freeze-drying processes.
