    Abstract: Sustained release oral drug dosage forms that comprise a tablet or capsule containing a plurality of particles of a solid-state drug dispersed in alkyl cellulose such as hydroxyethylcellulose or hydroxypropylcellulose. Once ingested the tablet or capsule disintegrates to disperse the particles into the stomach where they imbibe water to cause them to swell and also to become slippery, thus enhancing their retention in the stomach. Imbibed water from the gastric fluid dissolves the drug entrapped in the particles and the resulting solution diffuses from the dispersed particles, assuring that no solid drug, which with some drugs is more irritating, contacts the mucosal tissue. A number of embodiments of the dosage form utilizing different drugs are exemplified and the benefits are explained. Aspirin is one example.

  • Patent number: 5547943
    Abstract: A preparation containing an aluminum salt of a sucrose sulfate ester (sucralfate) and polyethylene glycol, and a process for preparation of the same are disclosed. Sucralfate is extensively used as a curative for digestive ulcers and has the capability of protecting the substrate protein. Sucralfate is mixed with polyethylene glycol to provide it with improved disintegrability and dispersibility and this renders sucralfate more useful as a medicine.
