Abstract: Provided herein is a pharmaceutical composition comprising an antagonist, an agonist, a seal coat, and a sequestering polymer, wherein the antagonist, agonist, seal coat and at least one sequestering polymer are all components of a single unit, and wherein the seal coat forms a layer physically separating the antagonist from the agonist from one another. Methods for manufacturing such a pharmaceutical composition are also provided.

Abstract: The invention combines two different subunits with different release profiles in novel sustained-release oral dosage forms. In particular, the oral dosage forms include a subunit that comprises an opioid analgesic and a sustained-release material, wherein the dissolution rate in-vitro of the subunit, when measured by the standard USP Drug Release test of U.S. Pharmacopeia XXVI (2003) <724>, is less than about 10% within about 6 hours and at least about 60% within about 24 hours; less than about 10% within about 8 hours and at least about 60% within about 24 hours; or less than about 10% within about 12 hours and at least about 60% within about 24 hours; the dosage form providing a duration of therapeutic effect of about 24 hours.

Abstract: Provided herein is a pharmaceutical composition comprising an antagonist, an agonist, a seal coat, and a sequestering polymer, wherein the antagonist, agonist, seal coat and at least one sequestering polymer are all components of a single unit, and wherein the seal coat forms a layer physically separating the antagonist from the agonist from one another. Methods for manufacturing such a pharmaceutical composition are also provided.

Abstract: Described is a pellet composition comprising a core element comprising morphine sulfate, a filler and a binder, wherein the morphine sulfate, calculated as the anhydrous form, comprises about 50 wt % to about 85 wt % of the total weight of the core element; and a coating disposed on at least a portion of the core element, the coating comprising an insoluble matrix polymer which is insoluble at pH 1 to 7.5; an enteric polymer which is insoluble at pH 1 to 4 and soluble at pH 6 to 7.5; and an acid soluble polymer which is soluble at a pH of 1 to 4, wherein the ratio of the acid soluble polymer to the enteric polymer is 1.45:1 to 2.5:1 on a weight basis. Also described are dosage forms comprising the disclosed pellets.

Abstract: Provided herein is a pharmaceutical composition comprising an antagonist, an agonist, a seal coat, and a sequestering polymer, wherein the antagonist, agonist, seal coat and at least one sequestering polymer are all components of a single unit, and wherein the seal coat forms a layer physically separating the antagonist from the agonist from one another. Methods for manufacturing such a pharmaceutical composition are also provided.

Abstract: A sequestering subunit comprising an aversive agent and a blocking agent, wherein the blocking agent substantially prevents release of the aversive agent from the sequestering subunit in the gastrointestinal tract for a time period that is greater than 24 hours; a composition comprising a sequestering subunit and a therapeutic agent in releasable form, wherein, optionally, the mechanical fragility of the sequestering subunit is the same as the mechanical fragility of the therapeutic agent in releasable form; a capsule or tablet comprising a sequestering subunit and a therapeutic agent; and a method of preventing abuse of a therapeutic agent.

Abstract: Provided herein are pharmaceutical compositions comprising an antagonist, an agonist, a seal coat, and a sequestering polymer, wherein the antagonist, agonist, seal coat and at least one sequestering polymer are all components of a single unit, and wherein the seal coat forms a layer physically separating the antagonist from the agonist from one another. Methods for manufacturing such a pharmaceutical composition are also provided. Methods for treating pain using such compositions are also demonstrated.
