Abstract: The present invention provides tissue expanders comprising biodegradable, chemically cross-linked hydrogels which are elastic in the dry state. These biocompatible tissue expanders are self-inflating and membrane-free. They swell slowly and elicit minimal negative tissue responses, while allowing for rapid and easy manipulation by the surgeon at the time of emplacement.

Abstract: A fast-melting pharmaceutical tablet comprises a porous, plastic substance, a water penetration enhancer and a binder. One or more drugs can be incorporated into the formulation at different stages of the process so as to afford a pharmaceutically active tablet. Methods of making the pharmaceutical tablet entail combining the porous, plastic material, the water penetration enhancing agent, and the binder so as to form highly plastic granules, which are compressed into tablets. The resulting tablets dissolve rapidly in the mouth and have good hardness with low brittleness. The tablets are particularly valuable to those who have difficulty swallowing conventional pills.

Abstract: Fast-dissolving pharmaceutical tablets comprising mannose are described. The mannose component imparts both structure-forming and fast-dissolution properties to the tablets. Granulation of tablet components and humidification forms strong liquid bridges at the surface interfaces of mannose particles, which leads to strengthened tablets. The mannose particles, however, remain porous following compression so that contact with moisture, e.g., saliva in the mouth, leads rapidly to tablet disintegration and dissolution.

Abstract: Fast-melting tablets contain particles of an active ingredient and ion-exchange resin complex to mask unpleasant taste associated with the active ingredient. The resin complex particles can be coated or uncoated to impart sustained release properties to the active ingredient. A fast-melting tablet also comprises a dry binder and bulk diluent to form highly plastic granules that are subsequently compressed into tablets.
