Mannitol is a sugar alcohol that is widely used in the pharmaceutical industry as an excipient [1]. It is a naturally occurring compound found in many plants, including fruits and vegetables [2].
How is Mannitol Used in Medications?
Mannitol serves multiple roles in pharmaceutical formulations. It is commonly used as a diluent in tablet and capsule formulations, adding bulk to allow for accurate dosing of potent active ingredients [1]. Its crystalline structure also makes it suitable for direct compression, a manufacturing process that simplifies tablet production [3]. In lyophilized (freeze-dried) products, mannitol acts as a bulking agent, contributing to the cake structure and stability of the final dosage form [4]. It is also used in parenteral (injectable) solutions for its osmotic properties, and as a diuretic in intravenous preparations [1].
What are the Different Grades of Mannitol?
Pharmaceutical-grade mannitol must meet stringent purity and quality standards set by regulatory bodies. Different grades may be specified depending on the intended application, such as for oral solid dosage forms, sterile injectable products, or lyophilization [1][4]. These grades differ in particle size distribution, flowability, compressibility, and other physical properties critical for manufacturing and product performance [3].
