Spray-dried lactose Finely milled lactose monohydrate is suspended in water, and spray-dried to give spherical agglomerates of crystalline lactose monohydrate in a matrix of amorphous lactose. The result is a product that both flows and compresses well. Spray-dried lactose is therefore very well suited to direct compression applications. DFE Pharma offers spray-dried lactose under the brand names Lactopress® Spray Dried and SuperTab® SD. Specialty range products offer increased tabletability compared to the key range products. Lactopress® Spray Dried 250 and SuperTab® 11SD are the DFE Pharma key range products.
