  • Publication number: 20030077306
    Abstract: Novel emulsion compositions which improve the rate and/or extent of absorption of drugs are disclosed. The novel emulsion compositions of the present invention include drug-containing emulsions adsorbed onto solid particles which may be further formulated into solid dosage forms, methods of preparing such emulsion compositions and their uses thereof. The emulsion compositions and their dosage forms improve the drug-load and the bioavailability of a wide range of drugs including drugs that are known or suspected of having poor bioavailability by the utilization of several different mechanisms.

  • Patent number: 6509036
    Abstract: The pharmaceutical compositions of the present invention comprise orally administerable dosage forms that use effervescence as a penetration enhancer for drugs known, or suspected, of having poor bioavailability. Effervescence can occur in the stomach, once the tablet or other dosage form is ingested. In addition to effervescence in the stomach, or as alternative technique, by the use of appropriate coatings and other techniques, the effervescence can occur in other parts of the gastrointestinal tract, including, but not limited to, the esophagus, duodenum, and colon. The site of effervescence and drug release is chosen to correspond with the segment of the gastrointestinal tract displaying maximal absorption of the formulated drug, or to gain some other therapeutic advantage.

  • Publication number: 20020110578
    Abstract: A pharmaceutical dosage form adapted to supply a medicament to the oral cavity for buccal, sublingual or gingival absorption of the medicament which contains an orally administerable medicament in combination with an effervescent for use in promoting absorption of the medicament in the oral cavity. The use of an additional pH adjusting substance in combination with the effervescent for promoting the absorption drugs is also disclosed.

  • Patent number: 6368625
    Abstract: A dosage form which rapidly disintegrates in the mouth and forms a viscous slurry of either microcapsules or a powder is described. The rapidly disintegrating dosage form is meant for direct oral administration by placing a tablet or capsule in the mouth of a patient. Upon disintegration, a viscosity of the resulting slurry increases so as to form an organoleptically pleasant viscous material which retards the spread of insoluble materials including the drug.
