  • Patent number: 6682759
    Abstract: A method is disclosed for manufacturing a pharmaceutical tablet for oral administration, the tablet combining both immediate-release and prolonged-release modes of drug delivery and using an immediate-release drug that is either insoluble in water or only sparingly soluble and is present in a very small amount compared to the prolonged-release drug. The method involves the use of particles of the immediate-release drug that are equal to or less than 10 microns in diameter, applied as a layer or coating over a core of the prolonged-release drug, the layer or coating being either the drug particles themselves, applied as an aqueous suspension, or a solid mixture containing the drug in admixture with a material that disintegrates rapidly in gastric fluid.

  • Patent number: 6676967
    Abstract: Methods for reducing flushing in individuals being treated for hyperlipidemia with nicotinic acid are disclosed. According to the methods of the present invention, flushing can be reduced in individuals under going nicotinic acid therapy without causing drug-induced hepatotoxicity to a level that would require the nicotinic acid therapy to be discontinued by orally administering to the individuals intermediate nicotinic acid formualtions having unique biopharmaceutical characteristics as a single dose once per day. While the methods of the present invention contemplate administering the intermediate release nicotinic acid formulations at any time during a 24 hour period, it is preferable to administer them once-a-day as a single dose during the evening or at night between about 6:00 pm. and 12:00 a.m., preferably between about 8:00 p.m. and 12:00 a.m., and most preferably between about 8:00 p.m. and 10:00 p.m.

  • Patent number: 6652874
    Abstract: Formulations have been developed for regional delivery of drugs, for example, into a cavity such as the pelvic region, peritoneal region, or directly on organs of interest. Regional delivery increases comfort and bioavailability of the drug, resulting in rapid and relatively high blood levels in the regions to be treated in the substantial absence of side effects due to the high levels required for efficacy following systemic delivery. In the preferred embodiment, these formulations consist of drug micro or nanoparticles, which may be formed of drug alone or in combination with an excipient or polymeric carrier. The excipient or polymer may be used to manipulate release rates and to increase adhesion to the affected region. The drug formulation can be applied as a dried powder, a liquid suspension or dispersion, or as a topical ointment, creme, lotion, foam or suppository.

  • Patent number: 6641838
    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.
