  • Rapid disintegrating tablets (RDTs) for pharmaceutical use and method for preparing the same
    Publication number: 20050053655
    Abstract: The present invention provides a fast-disintegrating tablet (RDT) and the method of preparing the RDT. The RDT contains a plurality of microcapsules which contains an active pharmaceutical ingredient surrounded by a polymeric matrix formed by a hydrogel. The microcapsules are separated from each other by a surfactant, particularly lecithin. The RDT is particularly suitable for use as a drug delivery system for antiacid or antiulcer drugs, such as famotidine. The RDT is further characterized by their its fast disintegration time of about 3 second to 3 minutes.
