  • Patent number: 6391335
    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.

  • Patent number: 6261601
    Abstract: A pharmaceutical composition in the form of tablets or capsules provides a combination of temporal and spatial control of drug delivery to a patient for effective therapeutic results. The pharmaceutical composition comprises a drug, a gas generating component, a swelling agent, a viscolyzing agent, and optionally a gel forming polymer. The swelling agent belongs to a class of compounds known as superdisintegrants (e.g., cross-linked polyvinylpyrrolidone or sodium carboxymethylcellulose). The viscolyzing agent initially and the gel forming polymer thereafter form a hydrated gel matrix which entraps the gas, causing the tablet or capsule to be retained in the stomach or upper part of the small intestine (spatial control). At the same time, the hydrated gel matrix creates a tortuous diffusion path for the drug, resulting in sustained release of the drug (temporal control). A preferred once daily ciprofloxacin formulation comprises 69.9% ciprofloxacin base, 0.34% sodium alginate, 1.03% xanthan gum, 13.

  • Patent number: 6207191
    Abstract: A drug delivery system (10) includes a first capsule half (12) having an inner chamber (16) containing a drug (18) therein. A plug (28) is disposed in a passageway (26) of the capsule half (12) for plugging the opening (24) thereof. The plug (28) is releasable from the passageway opening (24) upon the application of pressure from within the inner chamber (16). A pump mechanism, reactive with the external environment of the capsule half (12), causes an increase in pressure within the inner chamber (16) and forces the plug (28) out of the passageway (26) to release the drug (18) from the inner chamber (16) and out of the passageway (26). Thusly, after initial release of drug from a second capsule half (14) releasably mounted on the first capsule half (12), the first capsule half (12) provides a second pulse of drug release at a predetermined time after initial ingestion of the capsule.

  • Patent number: 6203817
    Abstract: Transdermal compositions, devices, and methods for the administration of a drug at reduced skin irritation levels are disclosed. More particularly, this invention relates to novel methods, compositions, and devices for the reduction or elimination of irritation or sensitization caused by an irritating or sensitizing drug when it is delivered transdermally. According to a preferred embodiment, transdermal administration of a drug salt of a non-zwitterionic drug is disclosed wherein the drug salt comprises a combination of surface activity and a low octanol-water partition coefficient. Such drug salts have been found to reduce irritation or sensitization to the drug being delivered while achieving therapeutically effective transdermal fluxes.

  • Patent number: 6190697
    Abstract: The effervescent formulation elation in the form of granules or of a tablet contains, in addition to the effervescent base, at least one water-soluble or at least suspendable plant extract whose particles are coated with at least one oily, fatty or waxy substance. At least one emulsifier and/or at least one antifoam may be present in the coating and/or as a further component of the mixture, in particular applied as a further component of the mixture to a pharmaceutically permissible filler as carrier. The individual phases are prepared by a procedure in which the plant extract or the filler is heated—preferably in a granulator, in particular in a vacuum granulator—and wet or mixed with a melt or solution of the oily, fatty or waxy substance or at least one emulsifier and/or at least one antifoam and then dried—preferably in a vacuum—and sieved to the desired particle size.

  • Patent number: 6187337
    Abstract: A particulate support matrix, and a dosage form made therefrom, and processes for making such support matrices and dosage forms, which disintegrate or dissolve in a matter of just a few seconds once placed into an aqueous environment. First, a porous particulate powder matrix comprising at least two polymeric components which will serve as the dosage form matrix is produced. The polymeric components have different solubilities. In a second step, a pharmaceutical compound, for example an antihistamine, decongestant, or antibiotic is combined with the powder. Other additives may also be added to the mixture. In a third step the mixture is formed into a dosage form. Finally, in a fourth step, a coating may be formed upon the outer surface of the dosage form to enhance the intactness and durability of the dosage form.
