  • Patent number: 9132096
    Abstract: The present invention relates to a composition comprising pharmaceutical active ingredients which are susceptible to, or have potential for, abuse. The invention provides an oral pharmaceutical composition comprising a first population of beads and a second population of beads. The first bead population comprises a pharmaceutically active ingredient susceptible to, or having the potential for, abuse. The second bead population comprises a gelling agent and a coating substantially surrounding the gelling agent, but containing no pharmaceutically active ingredient. The first bead population and the second bead population are physically separable, but visually indistinguishable to the naked eye. Upon ingress of water into the second population of beads, the gelling agent is caused to swell forming a viscous mass inhibiting or preventing the extraction of the active ingredient.

  • Patent number: 8329217
    Abstract: A dosage form that provides a controlled release of at least two different active agents is provided. Particular embodiments include a dosage form that provides therapeutically effective levels of a first active agent and a second active agent in a mammal for an extended period of time following oral administration. An osmotic device containing a bi-layered core is provided. The osmotic device provides a dual controlled release of both drugs from the core. The layers of the core are in stacked, substantially concentric or substantially eccentric arrangement.

  • Patent number: 8323691
    Abstract: Rapid and accurate determination of the formulation orientation of multi-layer capsule-shaped tablets with respect to different internal formulation layers proximate to the opposite narrow and rounded ends of the tablets is required. By including an appropriate color scheme in multi-layer osmotic tablets, detection of the formulation orientation is achieved by detecting the color at a spot location on a side of the tablet corresponding to one or another formulation layer or to one or another interface of two formulation layers depending on the formulation orientation of the tablet.

  • Publication number: 20120301547
    Abstract: A paliperidone double-layered osmotic pump controlled release tablet and the preparation method thereof are disclosed. The double-layered osmotic pump controlled release tablet comprises a rigid membrane, a push layer, a drug layer, an isolation layer and an aesthetic coating, wherein the rigid membrane contains a semi-permeable polymer, a porogen and/or a plasticizer and has one or more drug release orifices on one end, the push layer comprises an expanding material, an osmotic agent, a binder, a colorant and a lubricant, the drug layer contains a pharmaceutically active ingredient, a hydrophilic polymer, an osmotic agent, a colorant, a lubricant and an antistatic agent, the isolation layer is located between the inner surface of the rigid membrane and the push layer, and contains a hydrophilic polymer. The paliperidone double-layered osmotic pump controlled release tablet shows an increasing drug release rate at early stage and keeps a constant drug release rate at later stage.

  • Patent number: 8293799
    Abstract: The osmotic devices of the present invention include a single core comprising a salt of a drug and an osmotic salt, wherein the drug salt and the osmotic salt have a common ion. The release rate of the active drug is reduced, and the release profile of the active drug is modified, from a first order release profile to a zero order, pseudo-zero order, or sigmoidal release profile, by increasing the amount of the sodium chloride in the core of the device. In one embodiment the sodium chloride is used to modify a controlled release profile to a delayed and controlled release profile.

  • Patent number: 8252331
    Abstract: The osmotic devices of the present invention contain a unitary core comprising a salt of amantadine and an osmotic salt, wherein the two salts have an ion in common. The release rate of the amantadine is modified from a first order release profile to a zero order, pseudo-zero order or sigmoidal release profile by increasing the amount of the osmotic salt in the core of the device. The osmotic device includes a semipermeable membrane having a controlled porosity that can be adapted as needed to cooperate with the osmotic salt in providing a predetermined drug release profile. The osmotic salt need not be coated and it is in admixture with the amantadine salt.
