Also act as a binder in tablet 8) Applications in pharmaceutical formulation Lactose is widely used as a filler or diluent in tablets and capsules, and to a more limited extent in lyophilized products and infant formulas. Lactose is also used as a diluent in dry-powder inhalation. Other applications of lactose include use in lyophilized products, where lactose is added to freeze-dried solutions to increase plug size and aid cohesion. 9) Pharmacopoeial Specifications a. Density (true):1.545 g/cm3 (-lactose monohydrate) b. Melting point: 201–202°C (for dehydrated -lactose monohydrate) c. Solubility: Soluble in water 10) Stability and Storage Conditions: Mold growth may occur under humid conditions (80% relative humidity and above). Lactose may develop a brown coloration on storage, the reaction being accelerated by warm, damp conditions. The purities of different lactoses can vary and colour evaluation may be important, particularly if white tablets are being
