  • Patent number: 6776999
    Abstract: The invention relates to a device for delaying the pylorus passage of orally administered medicament forms. Said device comprises a component which expands upon contact with the gastric juice and a polymer coat which is permeable to liquids but not to gases. The device can contain an active substance whose release into the gastric juice is mainly controlled by the medicament form into which it is incorporated. Unlike conventional medicament forms with delayed pylorus passage, the release of the active substance does not so much depend on the kind and structure of the polymer coat but is mainly determined by the incorporated medicament form. The inventive device can be easily rolled or folded and can be filled into capsules.

  • Patent number: 6663896
    Abstract: A method and controlled release oral unit dosage form of acetylsalicylic acid (aspirin) delays the release of the drug until a predetermined time interval after ingestion. This enables the drug to reach optimal therapeutic blood levels at a time in the early morning when the events leading up to a vascular obstruction culminating in a heart attack or stroke are most commonly occurring after the drug is taken in the evening. The convenience of taking the drug every evening should enhance compliance. By arranging for the optimal blood level to coincide with the peak incidence of strokes, a much smaller total dose of the drug may be used than is normally prescribed. This may reduce the incidence of side effects that are dose related. This will make the prophylactic use of aspirin available to more of the population.

The capsule is covered with a coating (14) that dissolves within the body. The time release medication is not released until the covering is sufficiently dissolved to expose the medication. During surgery, the surgeon places placing a plurality of capsules (10-10n) in the patient's body at the surgery site. The respective capsules have different coating thicknesses so the medication contained therein is dispensed at different periods of time after the surgery as a function of the thickness of the coating.

  • 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.

  • Patent number: 6641840
    Abstract: The present invention relates to formulations for administering a growth hormone secretagogue. More specifically, the present invention relates to sustained release formulations for administering a growth hormone secretagogue and formulations for administering a growth hormone secretagogue that provide for a part of the dose of the growth hormone secretagogue to be administered using an immediate release formulation and part of the dose of the growth hormone secretagogue to be administered using a sustained release formulation.

  • Patent number: 6638536
    Abstract: The present invention provides storage stable, shaped particles of allotropic organic compounds. The particles of the present invention can be shaped according to the desired application. Preferred shapes of such particles are microspheres, particularly those having diameters of about 1 to about 1,000 microns. The stable shaped particles of the present invention are particularly well-suited to the fabrication of pharmaceutical formulations, particularly where sustained release and uniform bioavailability are desired. The storage stable particles are formed by a solid state crystallization of allotropic organic compounds. The solid state crystallization process of the present invention affords a means for achieving a storage stable crystalline form of said allotropic compound without loss or deterioration of the original particle dimensions.

  • Patent number: 6635284
    Abstract: Dosage forms for oral administration of a methylphenidate drug are provided. The dosage forms provide a substantially immediate dose of methylphenidate upon ingestion, followed by one or more additional doses at predetermined times. By providing such a drug release profile, the dosage forms eliminate the need for a patient to carry an additional dose for ingestion during the day. The dosage forms and methods provided are useful in administering methylphenidate and pharmaceutically acceptable salts thereof, which generally require one or more doses throughout the day.

  • Patent number: 6635277
    Abstract: A once-a-day controlled release drug delivery system of diltiazem hydrochloride is provided, which is bioequivalent in plasma profile of Cardizem CD. The fast, medium, and slow release fractions are prepared using various compositions and weight gains. The individual fill weights are computed and then are filled into the same capsule using specialized encapsulation equipment using a triple-filling process. A preferred membrane dispersion that is used for preparing the fast release fraction contains 0.2% of sodium lauryl sulfate along with 20% of water soluble plasticizer (triethyl citrate), and 2% silicone dioxide, based on quaternary polymethacrylate on the weight basis. This combination provides an initial pulsatile burst after a lag time of 2 hours, leading to in-vivo bioequivalence. The preferred membrane dispersion that is used for preparing the medium release and the slow release fractions contain 16% of water soluble plasticizer along with 5% silicone dioxide, based on quaternary polymethacrylate.

  • Patent number: 6635276
    Abstract: The invention relates to the use of a preparation containing a first group of particles and at least one other group of particles which is not identical to the first group of particles for achieving controlled release of an active ingredient present in the cores of the particles, in particular in the human and veterinary medical sectors. The preparation is administered orally, rectally, vaginally etc. The release of the active ingredient then takes place in the appropriate medium, and there is transmucosal absorption of the active ingredient.
