What is the Role of Mannitol as an Excipient?
Mannitol functions as a versatile excipient in pharmaceuticals, primarily used as a diluent, filler, or stabilizer in tablet and capsule formulations. It also serves as an osmotic laxative and cryoprotectant. Its physical and chemical stability, inertness, and compatibility with active pharmaceutical ingredients (APIs) make it suitable for various administration routes, including oral, injectable, and inhalation forms.
What Are the Key Properties Making Mannitol Attractive as an Excipient?
- Low hygroscopicity reduces moisture-related stability issues.
- High melting point (~165°C) supports thermal processing.
- Non-reactivity with APIs preserves drug integrity.
- Good taste-masking properties, especially in pediatric formulations.
- Capacity to act as a cryoprotectant in lyophilized products.
