  • Patent number: 5298261
    Abstract: A tablet that rapidly disintegrates in aqueous solution includes a partially collapsed matrix network that has been vacuum-dried above the collapse temperature of the matrix. The matrix is preferably at least partially dried below the equilibrium freezing point of the matrix. Vacuum drying the tablet above its collapse temperature instead of freeze drying it below its collapse temperature provides a process for producing tablets with enhanced structural integrity, while rapidly disintegrating in normal amounts of saliva. The tablet preferably carries a drug, such as acetaminophen. The matrix network of the tablet preferably includes a gum, a carbohydrate and the drug. Especially preferred embodiments also include a flavoring, a sweetener and surfactant. The gum is preferably acacia, guar, xanthan, carrageenan or tragacanth gum. The carbohydrate is preferably mannitol, dextrose, sucrose, lactose, maltose, maltodextrin or corn syrup solids.
