    Abstract: A pharmaceutical dosage form such as a capsule, a conventional or orally disintegrating tablet capable of delivering a nitrogen (N)-containing therapeutic agent having a pKa in the range of from about 5 to 14 into the body in a sustained-released fashion, in order to be suitable for a twice- or once-daily dosing regimen, comprises at least one organic acid, which solubilizes the therapeutic agent the drug prior to releasing it into the hostile intestinal environment wherein said weakly basic drug is practically insoluble. The unit dosage form is composed of a multitude of multicoated particulates (i.e., immediate-release beads, sustained-release beads and/or one or more timed, pulsatile-release bead populations) is designed in such a way that said weakly basic drug and said organic acid do not come into close contact during processing and/or storage for in-situ formation of acid addition compounds while ensuring that the acid is not depleted prior to completion of the drug release.

    Abstract: The invention concerns a method for producing a controlled-release pharmaceutical preparation with a particle-containing coating, the coating being derived from an aqueous dispersion of a film-forming water insoluble polymer and a water soluble pore-forming agent. By suspending, instead of dissolving the pore-forming agent, the resulting coating will contain particles of the pore-formers with a predetermined size that creates, when disintegrated or dissolved in the body fluid, canals or a network of pores through the polymer film. Due to this network, the film will get a good mechanical stability and are left intact after the release of the drug.

  • 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: 6649187
    Abstract: The invention provides a method and device for administering an amine drug, such as [S-(R,S)]-2-[4-[[(4-methyl)piperazin-1-yl]carbonyl]phenoxy]-3,3-diethyl-N-[1-(3,4-methylenedioxyphenyl)butyl]-4-oxo-1-azetidinecarboxamide), in a sustained release dosage form. The invention includes a pharmaceutical composition and dosage form containing a polyalkylamine polymer and an amine drug. The polyalkylamine polymer is a hydrogel that forms hydrated particles when exposed to an aqueous environment. When mixed with the amine drug in the core of a coated tablet, the polyalkylamine polymer controls the release of the amine drug into an aqueous environment of use. The hydrated particles of the polymer together with the amine drug are released from the tablet core through plural apertures in the surrounding coat.

  • Patent number: 6649188
    Abstract: Film-forming compositions are disclosed that can comprise, on a dry solids basis, 25 to 75 percent by weight of certain starch derivatives and 25 to 75% primary external plasticizer. The starch derivatives can be chemically modified starches that range in molecular weight from 100,000 to 2,000,000. The high levels of plasticizer in the films give excellent film flexibility and integrity. The films are also resistant to penetration by water, oil and/or grease.

  • Patent number: RE39069
    Abstract: The present invention provides a simple and improved multi-layered osmotic device (1) that is capable of delivering a first active agent in an outer lamina (2) to one environment of use and a second active agent in the core (5) to another environment of use. Particular embodiments of the invention provide osmotic devices in which the first and second active agents are similar or dissimilar. An erodible polymer coat (3) between an internal semipermeable membrane (4) and a second active agent-containing external coat (2) comprises poly(vinylpyrrolidone)-(vinyl acetate) copolymer. This particular erodible polymer results in an improved multi-layered osmotic device possessing advantages over related devices known in the art. The active agent in the core (5) is delivered through a pore (6) containing an erodible plug (7). The osmotic device (1) can be coated by a final finish coat (8).
